Spiraalboor KWB 258640 rechtsdraaiend 1 stk.

Spiral cutting drill bit KWB 258640 is a single-piece HSS M2 spiral drill designed for right-hand rotation. The cylindrical shank drill features a 130° point angle with a special polished section and a polished spiral with Quick Cut geometry for small swarf. It has a reinforced core and spiral shoulder, a specially shaped short spiral notch and an extra-robust design for efficient swarf removal and high heat resistance. The bit delivers reliable cutting performance particularly in stainless steels and is also suitable for all steel types, cast iron and cast steel. It is intended for effortless and energy-saving drilling with cordless or corded machines.

Advantages

The HSS M2 material and reinforced core provide durability and wear resistance while the 130° point and polished Quick Cut spiral reduce cutting forces and produce small, manageable swarf. The extra-robust construction and specially shaped short spiral notch improve chip evacuation and stability. High heat resistance ensures performance under demanding conditions and the cylindrical shank fits standard chucks for easy use.

Key specifications

How to use

Secure the cylindrical shank in the drill chuck and clamp it firmly. Select appropriate speed and feed for the material being drilled—lower speeds for stainless steel and harder materials. Use steady, even pressure and allow the drill to cut without excessive force. Retract occasionally to clear swarf if drilling deep holes. Provide cooling or lubrication where applicable to extend tool life and improve hole quality.

Recommendations

For best results in stainless steel and other hard materials, use reduced speed, light steady feed and appropriate cutting fluid. Inspect the drill before use and replace when worn to maintain hole accuracy and safe operation.
