●[M2 HSS]: Cuts much cleaner holes and much easier than average step bits. In general, M2 has 50% more tungsten and 150% more molybdenum, both of which are key elements for improving durability. Our additional vacuum heat treatment and nitride surface hardness treatment make performance even better.
●[4 Spiral Flutes]:Provides super fast, smooth and clean cutting.
●[Easier | Faster | Cleaner]:With our high-precision CNC processing and multiple optimized design details over the years, our design cuts easily, quickly and cleanly, surpassing the average ones on the market.
●[Non-Stop]:With our polished steps and size guides, you can see the target hole size while drilling. No need to stop and check in the middle of drilling. Save time and hassle.
●[Heavy Duty]:Cuts holes on stainless steel, hardened metal, mild steel, galvanized steel, aluminum, copper, plastic, wood or anything that has similar or lower hardness to these materials. Up to 2.7mm thickness for stainless steel.
