KWB 258633 spirálfúró

Spiral cutting drill bit KWB 258633 is a single-piece HSS M2 spiral drill engineered for right-hand rotation. The drill features a 130° point angle with a special polished section, a reinforced core and shoulder, and a short spiral notch for extra robustness. Its Quick Cut spiral geometry produces small swarf and improves chip evacuation, making the bit suitable for cordless and corded machines and offering reliable performance across stainless steel, other steels, cast iron and cast steel.

Advantages

The drill offers enhanced heat resistance and optimal cutting performance, particularly in all types of stainless steel. Its special polished spiral and Quick Cut geometry reduce cutting forces and generate small chips for easier removal. Reinforced core and spiral shoulder increase durability and reduce breakage risk during heavy use. The cylindrical shank and right-hand cut ensure compatibility with standard chucks.

How to use

Secure the drill bit in the chuck of a cordless or corded drilling machine. Mark the drilling position and start at low speed to locate the point, then increase speed and apply steady pressure appropriate to the material. Use cutting fluid when drilling stainless steel or other hard alloys to improve cooling and extend tool life. Retract periodically to clear chips when drilling deep holes.

Recommendations

For best results in stainless steel and hard alloys, use cutting fluid, moderate feed rates and avoid excessive speed to prevent overheating. Inspect the bit before use and replace if the cutting edges show significant wear or chipping.
