For example, most cordless drill/drivers produce about 50 foot-pounds of torque, and the average impact driver delivers about 125 foot-pounds. It employs both rotational force (torque) and short-burst concussive blows (impacts) to deliver an unparalleled amount of power. Unlike cordless drill/drivers and impact drivers, which excel at drilling holes and driving screws, the impact wrench is specially designed for tightening and loosening various hex-head bolts, nuts, and lag screws. ProMAXX Tool's ProCutter is one more example of our mission to provide technicians with tools and knowledge that make them more productive.What You Need to Know About Impact Wrenches How They Work Service leaders and General Managers are looking for more ways to become more productive. Technicians are under the gun to get trucks out of the service bay and back to work. The ProCutter will also remove burrs which can expose the remaining bolt to additional torque as it’s turned out – all in just five seconds. It will flatten the broken stud, giving a drill bit an even cutting surface and preventing the drill from walking and drilling off-center. Its blade and arbor design work to remove the partial thread left behind left from broken bolts. The ProCutter is designed to prepare the surface and threads that technicians will use to turn out the broken bolt. The ProCutter is the only product on the market that does that.” You’ve got to go in and clean the debris, corrosion and partial thread that is left behind. “The worst thing a technician can do is go in and try to turn out a bolt-on threads that were the reason for the break in the first place. “I’ve seen bolts broken off due to almost every factor you can think of,” said Del Rossa. Owner and President of ProMAXX Tool, Jeff Del Rossa, recommends the ProCutter a tool that consists of a cutting edge and an arbor and attaches to a ¼” drill chuck. This environment often leads to a partial thread being left behind in the softer aluminum of the head. When these bolts break, it’s because they are actually stretched, thus elongating the threads. When these bolts are heated to such high temperatures then exposed to cool water or moisture from the road or condensation, they can break under the slightest bit of tension. A notorious reason for breakage is the tremendous amount of heat bolts are exposed to, especially those on an exhaust manifold, adjacent to a turbo. What many technicians do not realize as they begin to turn an easy-out is that the state of the threads is what caused the bolt to break off in the first place – which unfortunately leads to an extractor broken off inside an already comprised bolt hole.īolts experience multiple environmental factors, all of which can lead to breakage. The other two options require the technician to leverage the existing threads to guide the remainder of the bolt out of the hole. Tapping the thread is a great option but does require some confidence, skill and patience to accomplish the job. They can weld on a nut, drill down the stud and tap the threads, or drill a pilot hole and use an extractor. When technicians are faced with this predicament there are a few options at their disposable. Whether working on commercial vehicles or maintaining a fleet vehicle, moisture, corrosion, heat and heavy loads can put major stress on bolts under the hood. Broken bolts happen – whether we like it or not.
