KWB 258660 jobbmenetes spirálfúró 1 db

HI-NOX HSS M2 spiral drill, sharpened with right-hand cut and cylindrical shank. The bit is uncoated (black appearance) and features a 130° point angle with a specially polished section and a polished spiral for improved chip formation and evacuation. Reinforced core, strengthened spiral shoulder and a specially shaped short spiral notch provide extra robustness and reliable chip removal. The drill is designed for high heat resistance and optimal cutting performance, particularly in stainless steels, and is also suitable for all steel types, cast iron and cast steel. It is intended for effortless, energy-saving drilling with cordless and corded machines.

Advantages

The drill offers a Quick Cut geometry for small swarf, reinforced core and spiral shoulder for increased stability, and a specially polished cutting and spiral section to reduce friction and improve chip flow. Its high heat resistance maintains cutting performance when drilling hard materials and extends service life under demanding conditions. The cylindrical shank ensures compatibility with standard chucks and the right-hand cut is suitable for conventional drilling operations.

How to use

Secure the cylindrical shank in the drill chuck and tighten firmly. Select an appropriate speed and feed for the material being drilled—lower speeds for stainless steel and harder alloys, higher speeds for softer steels. Use steady pressure and allow the drill to cut without excessive force. Retract periodically for deep holes to clear chips and reduce heat buildup. Use cutting fluid where appropriate to improve cooling and chip evacuation.

Recommendations

For best results when drilling stainless steel and hard alloys, use reduced speeds, moderate feed, and suitable cutting fluid; avoid prolonged idling under load to prevent overheating.
