Step Drill HSS Co-M35 Cobalt

These are brand new easy to use 1/4″ hexagonal shank Step Drill HSS Co-M35 Cobalt Drill Bit for cutting into wood or metal thin plate or hollow section – up to 5mm thick . This Bit offers a SUBSTANTIAL increase in the wear resistance and oxidation aspect over the more common and cheaper HSS4241 and HSS6542 bits.

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.

Application:

Choose a clean dry surface and mark your intended spot. We recommend that you center punch the material to prevent ‘wandering’. Apply lubricant, and with your step drill located in your variable speed reversing drill – simply drill and tap your hole.

Also, failure to use lubricant and or drilling fast can radically reduce the life of the tool 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.

Bit is sutable for Aluminium, Hardy Board, PVC, Nylon, Mild Steel, Carbon Steel, Stainless Steel (304 and 316)
