## Long description

The KWB COBALT HSS CO twist drill bit (MPN 248635, EAN 4009312486355) is a precision-ground, right-hand rotation drill designed for demanding drilling tasks in a wide range of materials. Made from HSS with 5% cobalt alloy, it has a bronze-coloured finish, a cylindrical shank and a 135° tip angle with cross-ground geometry to DIN 1412 C. The bit is self‑centering and made to industrial quality standards for high durability and heat resistance.
Advantages
This KWB cobalt HSS drill bit offers improved wear resistance and higher heat tolerance compared with standard HSS drills due to 5% cobalt alloying. The 135° tip and cross-ground cutting geometry provide precise centering and reduced walking on start, while the precision grind ensures consistent hole quality. The cylindrical shank fits standard drill chucks and the industrial-quality manufacture supports repeated use in tougher applications.
Suitable for
Drilling steel and alloyed steel
Drilling stainless steel grades A2 and A4
Drilling cast iron and cast steel

How to use
Secure the drill bit in a compatible drill chuck with a firm grip on the cylindrical shank. Select appropriate spindle speed and cutting lubricant based on the workpiece material (lower speeds and coolant for stainless steels and hard alloys). Start drilling with steady feed pressure to allow the self‑centering tip to locate the hole; withdraw periodically to clear chips when drilling deep holes. Follow standard safety practices including eye protection and secure workpiece clamping.
Usage recommendations
For best results, use cutting fluid when machining stainless steels, cast steel or other heat-sensitive materials, and reduce spindle speed compared with mild steel. Replace the bit if excessive wear or chipping appears to maintain hole quality and safety.
