## Summary description

The KWB COBALT HSS CO twist drill bit is designed for efficient drilling in various materials. It features a right hand rotation and comes in a blister package. Ideal for both professional and DIY use, this drill bit ensures durability and precision during operation.

## Long description

The KWB COBALT HSS CO twist drill bit is a precision-ground right-hand drill designed for demanding drilling tasks. Made from high-speed steel with 5% cobalt alloy, it has a bronze-coloured finish and a cylindrical shank. The tip angle is 135° with cross-ground geometry to DIN 1412 C for self-centering performance and reliable chip removal. The bit is intended for industrial use and engineered for high heat resistance when working with difficult materials such as steel and alloyed steel, stainless steel grades A2/A4, cast iron and cast steel, bronze and plastics.
Advantages
The 5% cobalt alloy increases red-hardness and wear resistance for longer tool life under high temperatures. Precision grinding and cross-ground DIN 1412 C geometry provide accurate, self-centering starts and consistent hole quality. The 135° tip reduces walking and improves performance in hard and stainless materials. Cylindrical shank and industrial build ensure compatibility with standard chucks and robust use in workshop and production environments.
Suitable for
Drilling in steel and alloyed steel
Stainless steel (grades A2 and A4)
Cast iron and cast steel
Bronze and non-ferrous metals
Plastics

How to use
Secure the cylindrical shank of the drill bit in a compatible chuck. Use suitable cutting speeds and feed rates for the material being drilled; lower speeds and steady feed are recommended for stainless steels and hard alloys to control heat build-up. Apply cutting fluid when machining stainless steel, cast iron and other heat-sensitive materials to extend tool life and improve chip evacuation. Clear chips regularly and avoid excessive pressure that could cause bit deflection or breakage.
Usage recommendations
For best results when drilling stainless steel or other hard alloys, use a well-maintained drill press or stable hand drill, keep speeds moderate, and apply appropriate coolant. Replace the bit when wear affects centring or hole quality.
