Spiral cutting drill bit KWB 258610 is an HSS M2 spiral drill designed for right-hand rotation. The single-piece cylindrical shank drill features a 130° point angle with a specially polished section and a Quick Cut spiral geometry that produces small swarf and facilitates chip evacuation. The drill has a reinforced core and spiral shoulder, a specially shaped short spiral flute and a robust design for heat resistance and stable performance. It is optimized for drilling stainless steel but is also suitable for all steel types, cast iron and cast steel, and works efficiently with cordless and corded machines.

Advantages

This KWB HSS M2 drill provides optimal cutting performance in stainless steels due to its heat-resistant material and polished cutting sections. The Quick Cut geometry and shortened spiral notch improve chip formation and evacuation, reducing effort and energy consumption. Reinforced core and robust construction enhance tool life and reliability during demanding drilling tasks.

Key specifications

How to use

Secure the drill bit in the chuck of the cordless or corded drill, ensuring the cylindrical shank is clamped firmly. Select appropriate speed and feed for the material being drilled—lower speeds for stainless steel and harder alloys. Use steady, even pressure without excessive force to allow the Quick Cut geometry to form and evacuate chips. Withdraw periodically for deep holes to clear swarf if necessary.

Recommendations

For best results when drilling stainless steel, use cutting fluid or lubricant and operate at reduced speed. Replace the drill if wear affects the polished cutting section or if chipping occurs; worn drills increase heat and reduce performance.
