Each tool produces a clean chamfered hole in the material. Can be used on plate, bar, tube, or box section. Cutting fluid or drill lubricant is recommended (the type of fluid depends on the material being machined). As with all machining, it is best to go slow, keep the tool cool, and use LOTS of lubricant. They are industry fabrication quality and IMHO – one of the best hand tools around
Choose a clean dry surface and mark your intended spot. We recommend that you mark or center punch the material to prevent any ‘wandering’. Apply lubricant if necessary, and with your 8mm extra long drill bit located in your variable speed reversing drill – simply drill your hole.
Please understand that failure to use lubricant and or drilling fast can radically reduce the life of the 8mm extra long drill as a dull or burnt tip on the drill tap pretty much destroys the tool.. Injecting cold water while working, can effectively extend the service life of the drill bit.
