High Speed Steel Drill Bits (HSS) is an important metal cutting tool made of high-speed steel material, mainly used for drilling and reaming. Its design structure is similar to traditional drill bits, but it has better performance through excellent materials, refined manufacturing processes, and excellent coating technology.
Material: HSS4241,HSS4341,HSS6542(M2), M35(cobalt 5%),M42( cobalt8%)
Diameter:0.5-13mm 13.5-28mm(Shrink shank drill, shank dia 13mm)
Surface Finishing: White, TIN coated, Rainbow Color, etc.
Process: :Fully Ground, Milled, Roll Forged, Roll&Polished
Stability: Due to the professional design of high-speed steel drill bits, they have stability during use, preventing rotation deviation and drill bit fracture.
