If you are using a professional contractor, the different types of exercises on a daily basis in the course of your work, you'd probably already know what kind of drill you need for a specific task. But what about the person who does not work with every day tips. This person probably knows that requires a specific activity or task to use a drill, but can not be sure, is required over what kind of drill. Choosing the right drill can be a daunting task and there is really no surprisewith all types of exercises to choose from. We have:
Basic Exercises VSR Drill Drill / Driver Rotary Hammers Impact Drivers / Keys Impact Drills right angle drill Spade handle drill
Perhaps you have been looking for tips and other problems such as:
VSR What does it mean? What is the difference between SDS and spline drive? As the spindle size does not matter? What is the difference between the spindle and stuck without a key? What is a hexagonDrivers? Do I have a cordless drill or corded? What type of cordless battery is best? What is using the clutch?
He came several years ago, when first-hand drills around, there were not many ways out of brands to choose a drill. In practice, the exercises were all wire had entered all of chucks and rotated in one direction and speed. So the choice fell not too difficult. Just choose a brand that you like.
Things have certainlyhave changed over the years. There are now many opportunities to turn around the head of a person. There are more changes and innovations in the works, as I write this. While the scope of the cover of this manual is not able to penetrate any kind of existence, we will try to cover most. My goal in writing this article is to those who have difficulty deciding what kind of drill they need help, so let's get started.
The wire baseDrill
This is the simplest of hand-held drills. This is a simple drill with a speed and direction. It 'very good for metal drilling in wood, metal, plastic and soft. It is the ideal choice for applications such as drill to be used for driving screws. Since speed is not variable, and the drill with a higher speed, probably two strips the screw head or leave the screw head if you tried. Probably not many of thesetoday as their uses are rather limited.
VSR Drill
VSR stands for "variable speed, reversible." These exercises, both corded and cordless versions to come, as will most of all drill here. The top speed is varied the amount of pressure on the trigger. The farther the trigger, the higher the speed. There is also a switch, usually near the trigger that reverses the operation of the drill. As you can imagine, these differentAdvantages over the drill of basic cable. In addition to being able to perform all the basic functions of the drill string, giving a more suitable, although still limited ability to drive screws, bolts and small. Since the rate is variable, you get a chance to get into harder material without overheating the drill bit.
A disadvantage of this type of exercise is trying to maintain a certain rpm when the throttle is being very difficult. It takes some skill and a little 'getting used tobe used in order to be able to constantly drive screws without removing the head, driving the screw too deep or bending of the screw head. The reversible feature allows you to remove the screws, bolts and threaded back again out of print, if the drill is locked or jammed.
VSR Drill / Driver
The VSR drill / driver has all the features of a standard VSR drill with the added bonus of a lower speed / higher torque. Another feature usually found in theseDrill is an adjustable clutch. These are probably the most common types of everyday cordless drills are now on the market. The great advantage of the low speed / high torque setting is that now you can screws and bolts necessary delay in the low speed, without trying to keep the trigger in a drive certain position. The adjustable clutch to keep you from driving the screw too far, remove the screw head or break the screw head. The clutch will also prevent reaction torqueWhat happens if you try a little 'jam or a screw bottomed out and the drill to rotate in the opposite direction. In addition, you also get a higher torque at low speed adjustment range of the engine, that you missed, if it means using a standard VSR drill screws and torque more. These exercises usually have a slide switch that toggles between the two settings. Just in setting high speeds, functions as a VSR drill driver. In the low speed / high torque setting, the drilla driver for driving screws and small effective size. Some of these exercises can be set between 3 ° that the compromise between speed and torque in order to improve the speed / torque setting for the application.
The VSR hammer drill / driver
You must drill into concrete, stone or brick? If yes, then you should consider a hammer drill. This type of drill uses a hammer or pounding action as the drill rotates. The dramatic action of the bitWhat this exercise is to bite into the concrete, stone or masonry. If you try a non-hammer-type drills to use, we have difficulty in penetrating the hardened concrete, stone or masonry, and possibly overheat the bit, or something that would be trapped in matter. When drilling concrete, stone or brick, you also want to be safe and use a masonry drill bit. A little 'stone has been specially designed for drilling these materials. Depending on the material, and the drilluses the bit, you can usually expect to be able to practice effectively holes in concrete, stone or masonry to about the "diameter 1 / 2. VSR hammer drill / drivers are all the features of a drill VSR / drivers as well as function as a hammer drill to launch. With a switch to their versatility, hammer drill / drivers have become a popular choice among business professionals and do-it-yourself. would have some practical applications, to connect or holes Anchor ConcreteTAPCON screws for attaching components such as light posts and railings of concrete surfaces or devices connected to walls of concrete blocks, stone or brick. Today one of the most respected and valued professional drill / driver market is the DeWalt DC925KA.
Impact Drills
Think of a hammer larger, more powerful version of a hammer drill with an added bonus. It also works like a small jackhammer. These exercises are dedicated for the purposeDrilling and chipping concrete, stone and masonry. They are generally not designed for drilling in wood or other similar materials. Rotary hammers designed to use a little 'special slips in the chuck. The most common types are the SDS and spline drive. The type of drill bit that goes on. SDS drills are available in different sizes so you have the size drill to get your hit. If you want to practice many large holes with a diameter in concrete or stone, then thisthe type of dill that you need.
As mentioned earlier, this exercise also works like a small jackhammer. From a switch you can turn off the computer by moving the rotation, then put a little 'chisel and you're ready to go. During drills should not compete with a jackhammer full size, are very useful for many smaller jobs such as removing stones and ceramic tiles, stone blocks and removing the existing wall or ceiling construction, scrape Malta unwanted or paid, the chipping roughEdges of concrete, and removing excess cement from the concrete forms or other surfaces.
Traditionally, all rotary hammers Cordless batteries have been seen since they were not able to operate the energy required is a hammer drill. But everything changed with advances in lithium battery technology and design tools. The popularity of cordless rotary hammer drill is growing rapidly. Some cordless hammer drill rivals, and perhaps even exceedmeet their counterparts with cable. An example is the Bosch 11536VSR found in a control instrument of power that HGTVpro 1 / 2 "holes in the concrete faster than the tool of the drill is corded counterparts.
Impact Wrench / Impact drivers
Screwdrivers are quickly a hot topic among contractors and do-it-yourself and with all the added advantages of an impact driver, it's no wonder. If you have lots of long screws, anchor bolts, or take a lot of screws and bolts must be mountedfast and simple, so a driver has to impact you.
The driver has a serious impact VSR drill, until the time is needed as additional torque. This is when the impact kicks Do not confuse action with the action of a hammer drill hammer. The difference is that a hammer "pounding" on the tip laterally along the length of the drill, as shown in the chuck of the drill driver, the impact of impacts in a direction of rotation. The result is a huge increaseCouple. The effects of the screw also causes the screw to grab something less slippage, with the possibility of removing the screw head. As an added bonus, the amount of force the operator must apply for the tip to maintain the lives of a small slippage is greatly reduced, resulting in less user fatigue.
Screwdrivers have a quick-change bit holder for hex shank bits of acceptance, which are now being jointly developed by many other bits and inserts and socketDriver bits. This style bit support really makes a transition between the bits a breeze. Support This bit is the main difference between a driver and impact wrench. A key impact is a square to accommodate both 3 / 8 "or 1 / 2" sockets, depending on the model of the key impact.
Driver and Wrench have impact drill also provides a size advantage up to four times more torque than a comparable size VSR. This means that a smaller tool for a specific task that can be usedfurther reduces user fatigue, especially when working overhead. The small size also offers the opportunity to work in smaller rooms, and if the impact driver uses lithium-ion technology, the tool weight is further reduced.
This is a driver of special effects that stands out. Tools, tool a test of the magazine Commerce, 9 of the best key line of cordless driver impact of the 9081-22 Milwaukee was able to overtake the group when pushed up. This tool has sent 48 4 "longTimberlock screws in the field before it was a battery, there was no significant slowdown. Timberlock screws have a long screw with hexagonal head. They are usually used in outdoor applications such as gardens, fencing and construction of bridges used because they require no drilling. Just think of the time you can save by using a screwdriver and screws, no drilling required might think tanks.
Angle Drills
Corner drills, as the name implies, they feed at right angles to the positionBody of the drill. Angle drills are capable in tight spaces where other drills just do not get as between two closely positioned wall studs, which makes this exercise particularly useful for plumbers and electricians is to drill.
These exercises, both corded and cordless varieties, and a wide range of formats. The smaller right angle drills are suitable for orders of small and medium enterprises in the pines and other soft materials. Can handle the heavy models much more difficult jobMaterial thick oak. One thing to note when models should be more severe reaction torque. Thanks to the design of the drill at right angles, if the bit should remain locked, the drill body all turns into a diet that leads to potentially cause damage. And 'generally a good idea to get the drill floor against a wall stud or guardian. Some models are equipped with a torque limiter or clutch to prevent this occurrence. This model is equipped with a torque limiter, theMakita DA4031 [http://www.thetoolspot.us/Products/Makita/Makita-DA4031/MAKITA-DA4031.html]. The heavy-duty right angle drill was the overall winner of the test tools of Commerce of some of the top right-angle drills.
Spade Handle Drills
If spade handle drills are mentioned, you could probably think of mixing drywall compound. The mixture of drywall compound or similar substances is one of the most used applications spade handle drills. These exercises areDesigned with a low torque at high speed that is suitable for mixing with dry mud. Special Attacks mixer drywall can be used in feed for that purpose.
Although these exercises are very suitable for mixing dry mud and similar substances that require mixing, this is certainly not the only use for this type of drill. The pair aggressively for the production of these exercises make it ideal for drilling large holes in wood and other materials with spade bits, drill bits and hole sawsto as large as 5 "in diameter.
Many of these exercises are a rocker or a similar type of switch for rapid switching between forward and backward, reverse the jammed bits and mixing aid dried mud. In addition, these exercises are typically supported by an additional handle side and a handle of the spade in the control of the instruments.
Questions and answers related to perforation.
VSR What does it mean?
VSR stands for variable speed reversible. Drill with this function canoperate in forward and backward operation and variable speed. Most likely, the tip has a switch or push button to change the direction from front to back. In general, the speed varies in terms of how the trigger.
What is the difference between SDS and spline drive?
SDS and spline drive, refer to two types of technology bits used in rotary hammers. There really is no difference in performance of the two species, which will chooseJust one question, what kind of tip are your specific needs. There are different sizes of bits SDS, SDS, SDS + and SDSmax belong. Smaller hammers use SDS + or SDS bits, where more impact drill or bit hard SDSmax spline. As the name suggests, the bits of a spline spline drive, while the SDS bits are concave depressions in the well.
Why size matters spindle?
Chuck basically determined what the tip size can beUse according to the size of the tree drill. With the exception of impact hammers and drivers / keys, to use a particular type of food rather than do more typical hand drills with either a 3 / 8 "or 1 / 2" chuck. Most of your smaller drill "will use the chuck during heavy models typically have a 1 / 2" with a 3 / 8 Chuck. You can not put a drill with a "shank in a 3 / 8" 1 / 2 chuck, but you can get a little 'with an "attack on a 1 / 2" 3 / 8 spindle.
What is the difference between the wedge andKeyless chuck?
Years ago, all hand-keyed chuck. To move the food to the drill, you have a small instrument called a chuck key. Most 3 / 8 "and many spindles 1 / 2" Spindles are now varieties now without a key. Chuck, as the name suggests, not with a key. Instead, the food is designed so that a person bit easier to put food on hand. While no key is faster and easier to use, can not put an end to the bitso firm and so they have the same power company like chuck. This failure to maintain power have the potential to round shank bits slipping in the chuck. For this reason, there are many high-torque drill with heavy input Chuck.
What is a hex-driver?
A hex driver is just another name for an impact wrench. Hex refers to the type of support points used. These exercises use a hex-shank designed to slide into the bracket. This type of support while 'is alsochanging bits a breeze. Impact wrench, with a square on the opposite side to accommodate both 3 / 8 "or 1 / 2" drive sockets.
Do I have a cordless drill or corded?
This can be a difficult decision for some. The industry trend is increasingly on wireless technology. The first battery-operated drill on the market left much to be in power and duration to be desired. Over the, years wireless technology to the point that many cordless tools now improved with the competitionand also perform better in many cases, than their colleagues with cable. With the power and performance is always close to the same choice is basically the price. Are you ready to make some money and deal with the inconvenience of unplugging the power cord to save, or would you rather spend a little 'more and have complete freedom of movement? The choice is yours.
What type of cordless battery is best?
The machine tool industry is currently a tendency of lithium-ion battery. With allthe advantages of lithium ions, it is easy to see why. If you compare lithium ion, nickel-cadmium batteries, lithium-ion battery charges faster, runs longer, last longer constant power, weighs less and save more to pay. The disadvantage is that lithium-ion battery costs more. However, the price difference does not exceed the benefits received in the retention time of performance and cost.
What is using the clutch?
Most of the drill / drivers and hammers are adjustableCoupling. The clutch is typically used when driving screws, bolts or screws. The coupling is designed so that once a couple has certainly been reached, the clutch to slip and cause the rotation of the feed and turns no more. There are several reasons for this. One thing that will strip the screw head when the bit is rotating. Not two, one car you drive the screw too deep. Three reaction torque when the screw or nut at the bottom do not twist the wrist. Many exercises produce enoughReaction time to physical damage, when the clutch is not used. Many heavy-duty drill capable of large amounts of reaction time did not have a built-in adjustable clutch, or a built-in torque. One, finally, the clutch protects the motor from damage drill.
