How to drill Stainless steel video
Stainless steel, high hardness - how easily can it be drilled with a hand power drill and a TTP Hard Drill Bit?

The work hardening effect when drilling stainless steel is the main cause of problems. Centre punching with conventional conical shaped punches can result in enough localized work hardening to make drill entry difficult. This can make the drill tip deflect or wander, glaze the surface and/or blunt the drill tip and result in drill breakages, particularly where small diameter holes are being drilled. During drilling it is essential to maintain the feed to cut through the work hardened layer generated as the metal is cut.

TIP:
Drill slowly and allow the bit to do the work. If you apply too much pressure, friction will cause your drill bit to redden with heat which in turn will blacken the stainless steel. The same will happen if you engage the drill to its full speed. The trick here is to find a happy medium, that "sweet spot" at which the drill, the bit and the metal cooperate fully.
