Spiral cutting drill bit KWB 258635 Right hand rotation 1 pc

HI-NOX HSS M2 spiral drill bit with right-hand cut and cylindrical shank, uncoated black finish. The tip has a 130° point angle with a specially polished section and a polished spiral with Quick Cut geometry designed to produce small swarf. The flute and core are reinforced and the short spiral notch is specially shaped for robust performance and optimal swarf evacuation. The tool is extremely heat-resistant and delivers reliable cutting performance, particularly in stainless steels, and is also suitable for all steel types, cast iron and cast steel. Supplied as a single spiral cutting drill bit (KWB 258635) for efficient drilling with cordless or corded machines.

Advantages

The KWB 258635 offers high wear resistance due to HSS M2 material and an increased core for stability. Quick Cut spiral geometry and polished cutting edges reduce cutting forces and improve chip control. The 130° point and refined cutting section enhance centring and reduce walking. Designed for robust use, the drill bit withstands higher temperatures and maintains cutting performance across a wide range of ferrous materials.

How to use

Secure the KWB 258635 in the drill chuck and tighten firmly. Select a suitable drilling speed for the material: lower speeds for stainless steel and harder materials, higher speeds for softer steels. Use steady, even feed pressure; avoid excessive force. For deeper holes, periodically withdraw the drill to clear chips and reduce heat buildup. When drilling stainless steel or other heat-sensitive alloys, consider pecking technique and use appropriate cutting fluid if required.

Recommendations

For best results, use cutting fluid when drilling stainless steel and maintain correct speed/feed settings for the material. Inspect the shank and cutting edges regularly and replace the bit when wear affects performance.
