Step Drill Bits


Drill multiple size holes with the one bit! You can drill through plastics and un-hardened metals (such as aluminium or copper sheeting etc) up to 4mm thick! A great benefit of using the step drills is all you need to do to de-burr the hole is drill a little bit further so that the next size up touches the hole! Made from high speed stainless steel (HSS), they will last for a very long time.
Two sizes available:
4 - 12mm drill in 1mm steps - TD-2436
12 - 20mm drill in 1mm steps - TD-2438
