De-Burring Tip, Enhanced Hole Saw Use and More

摘要

When cutting large amounts of EMT or rigid conduit, you can speed up the process by using a tapered drill when you need to de-burr the pipe. Pipes can be de-burred in no more than 5 seconds, and it's a great way to save time along with doing an excellent job of the de-burr. Those of us who use hole saws know that when the pilot bit passes through a metal surface and the hole saw teeth meet the surface at high speed, they dig in and twist, causing the pilot bit to bend or snap. However, you can use a fender washer as a clutch when the pilot bit passes through, so the teeth do not catch. If you don't have a washer available, you can set the drill on driver mode and adjust the clutch to setting 2, 3 or 4. If the hole saw teeth catch when the pilot bit passes through the metal, the clutch will go into action and save the pilot bit from bending or snapping. Then stop, set the selector switch back to drill and continue cutting your hole.
