Agonizing; extremely distressing, unpleasant, or emotionally disturbing; having a severe effect on one's feelings. What a gut-wrenching loss for the young athlete, who poured her heart and soul into this match. Kids today are so desensitized that images of violence their grandparents would have found gut-wrenching now barely even register a response.
Automotive repair shops each have their own unique selection of tools, but almost all have one tool in common: the impact wrench. An impact wrench, which may also be called an air gun, air wrench, or torque gun, is a power tool that puts a high-torque output in the palm of your hand, without much work on your part. Rather than tightening a bolt by hand, which would not give you enough torque to ensure it was completely tight and safe, you can use an impact wrench to torque it and ensure it is tight. The wrenches have a socket wrench design, which is often used to repair automobiles and other heavy equipment. It can also be used in construction projects or product assembly when the products are large and heavy.
Great comparison test, better than the others I read online. I ended up buying the first gen Milwaukee, which is still a great gun. I used a co-workers and was impressed pulling lug nuts off a one-ton dump truck. I was able to get the gun, hard case, set of Milwaukee-branded impact sockets, two 5.0Ah batteries, the charger, gun nose protection boot, and Milwaukee LED worklight for $450. Too good a deal to pass up.
The fact that the Milwaukee 2763 Gen 1 high torque now has a stronger big-brother, but still finished 3rd deserves big kudos. In fact, receiving 86.1 points, it only misses 2nd by 0.3 points. While some others above suffered by finishing mid-pack, this is actually a plus for the Milwaukee. The difference is, the 2763 didn’t drastically fall short in any area, like the others. Even though the price is higher than several, with it’s 5-year warranty, features, and ergonomics, it’s still a great value.
If you find yourself working with automotive equipment (click here for cordless impact drivers or see these brushless impact drivers) or on mechanical based projects quite often, you likely know the benefits of having the best cordless impact wrench available on today’s market. Having such a pristine tool helps to make work an easier process and allows you to go about your day to day tasks with ease. You’ve probably been at the point in life before where you’ve had to settle for tools that were second best.
Was anemic at best, 500 ftlbs rating, apparently not on the one I purchased. The metal housing between the CH logo and the socket connection nub is forms sheet steel. Not a cast alum like on a normal impact hammer, so if you drop this more than 12'' onto concrete, it bends the thin metal housing and the tool no longer rotates. Either install padding and carpet in your garage, or look for another tool.
When a nut or a bolt head is in a recess below the surface of a bolted member, a socket wrench must be used; this is essentially a short pipe with a square or hexagonal hole and either an integral or a removable handle. Modern socket wrenches are made in sets, consisting of a number of short sockets with a square hole in one end that fits a removable handle and 8- or 12-point holes in the other end to fit various bolt and nut sizes. There are several types of handles and extensions, such as a T handle, screwdriver-grip handle, and a ratchet handle (see ratchet).
While pistol impact wrenches are bulkier, their grip style is more ergonomic to prevent strain on your hands, which in turn allows you to work for longer periods without fatigue. Some of these models can equip side handles which let you use your weight for greater leverage and to maintain a proper working angle. If you don’t need the special fit of an inline wrench, a pistol-style impact wrench is usually the ideal choice.
Many mechanics probably have the MAC Tools BWP151 in their tool arsenal, and rightly so. This is a very powerful impact gun, and it shows. In the end, the MAC BWP151 finished with 81.4 points in our shootout. In the power category, it and the DeWALT finished neck and neck, in 3rd and 4th place, so it delivers plenty of power. The MAC Tools impact should have done much better in our speed (repetitive power) testing, but it seemed to have a fraction of a second longer lag, from the time you pull the trigger until the gun starts.
Finishing in the Runner-Up position (2nd place) is the Ingersoll Rand W7150. The fact that this is nearly a 5-year-old tool deserves huge props for fighting past these other great entrants. It finished a solid 2nd in power testing and 3rd in repetitive power (speed) testing. It’s the lightest tool of the bunch, weighing only 6.88 pounds, with the 5.0 Ah battery intact.
Look for design enhancements, such as all-metal construction for the gear housing or high-strength plastic overmolds, which helps to prevent damage due to impacts or being dropped. Impact wrenches with brushless motors have fewer moving parts, which means that there’s less of a chance of components breaking down, and maintenance is easier to perform.
When compared to many other power tools, cordless impact wrenches are quite specialized in what they do. Large nuts and bolts may not need to be removed or tightened as often as smaller screws. But when you do need to adjust one, a cordless impact wrench will save you both time and energy. They can also loosen and tighten nuts and bolts much more accurately than hand tools such as sockets and ratchets, which is critical when it comes to working with larger bolts or on machinery.
In operation, a rotating mass is accelerated by the motor, storing energy, then suddenly connected to the output shaft (the anvil), creating a high-torque impact. The hammer mechanism is designed such that after delivering the impact, the hammer is again allowed to spin freely, and does not stay locked. With this design, the only reaction force applied to the body of the tool is the motor accelerating the hammer, and thus the operator feels very little torque, even though a very high peak torque is delivered to the socket. (This is similar to a conventional hammer, where the user applies a small, constant force to swing the hammer, which generates a very large impulse when the hammer strikes an object.) The hammer design requires a certain minimum torque before the hammer is allowed to spin separately from the anvil, causing the tool to stop hammering and instead smoothly drive the fastener if only low torque is needed, rapidly installing/removing the fastener.
