Don't often do reviews but thought I would for these. Read other reviews about this type of drill and many are critical, saying drills blunt easily or are only suitable for softer materials. These are brilliant. With a small pilot hole they easily enlarge the hole in 3mm mild steel to any diameter with just a bit of lubricating oil. Much quicker and easier than conventional HSS drills. Best in a pillar drill but can be hand held as long as you prepare for the occasional kickback. If and when they blunt will definitely buy again. Well recommended.

Perfectas para perforar con diferente calibres. Las diferentes anchuras de cono permiten usarlas con diferentes profundidades. Lo he empleado con aluminio grueso y con chapa de acero y es demoledor. Para amantes del bricolage es imprescindible

Far cheaper than the DeWalt of similar design. Work very well. I can't speak to durability, because I haven't used them long enough. But, as of right now, they're worth every penny.

I use it in fine woodworking. It saves a lot of time on larger holes on sensitive pieces, by replacing the use of successive drill bits to approach the final size. Very pleased with its design detail and precision.

Amazingly big, fast and clean! I would suggest a face shield on steel studs though. Works great on thin and thick gauge studs so I assume stainless steel would be no different. It stays centered well too, even though I use a mid torque impact gun
