Drill Bit Long HSS Steel ALL SIZES
Extra Long Drill Bit Bits are easy to use for cutting into wood or metal – and they are long enough to do an Intermediate post – because (of course) you know to drill in from both sides…
Description
Drill Bit Long HSS Steel are easy to use for cutting into wood or metal thin plate or hollow section – and they are long enough to do an Intermediate post in 1 pass! (But we recommend coming in from each side with a template – simply meet in the middle)
Each tool produces a clean 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
Application: 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 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 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.
