## Long description

Right hand cut, type N twist drill bit made from HSS with 5% cobalt alloying. The precision-ground, bronze-coloured drill features a 135° tip angle and cross-ground geometry to DIN 1412 C for self-centering, cylindrical drilling.

Advantages
The kwb COBALT HSS CO drill bit combines cobalt-alloyed high-speed steel and precision grinding to provide enhanced wear resistance and thermal stability during high-speed or heavy-duty drilling. The 135° tip and cross-ground design ensure accurate, self-centering starts and reduced walking, while the cylindrical shank supports reliable clamping in standard chucks.

How to use
Secure the drill bit in a suitable chuck and select appropriate spindle speed and feed for the workpiece material. For stainless and alloyed steels, use lower speeds and moderate feed to avoid overheating; for cast iron and bronze higher speeds are acceptable. Use cutting fluid or coolant when drilling metals to extend tool life and improve chip evacuation. Apply steady pressure and allow the drill bit to cut without forcing to maintain accuracy and prevent damage.
Usage recommendations
For best results when drilling hard or stainless steels, use cutting fluid, moderate feed rates and reduced speed compared with mild steel. Replace the bit when wear affects centring or hole quality to maintain precision.
