Sada vrtákov KWB 258819 19-dielna pravotočivá

HI-NOX HSS M2 spiral drills with a 130° point angle and special polished sections are supplied in a 19-piece set (KWB 258819) for right-hand rotation. The drills have a cylindrical shank and a black, uncoated finish. Their Quick Cut spiral geometry and reinforced core provide improved chip control and high heat resistance, making them suitable for cordless and mains-powered drilling machines.

Advantages

The drills feature a special polished cutting section and a Quick Cut spiral for producing small swarf and efficient chip evacuation. A reinforced core and reinforced spiral shoulder increase robustness and tool life under heavy loads. The 130° point angle with a polished tip improves centring and reduces walking. The black, uncoated surface retains heat resistance while maintaining cutting performance in stainless steels and other common engineering materials.

How to use

Secure the required drill bit from the 19-piece set in the chuck of a cordless or corded drilling machine. Set an appropriate spindle speed for the work material and, where possible, use cutting fluid when drilling stainless steel to extend tool life. Apply steady feed pressure and avoid excessive side loads. After drilling, clear chips from the flute before continuing with additional holes.

Recommendations

For best results in stainless steel, use moderate speeds and light to moderate feed pressure with intermittent pecking when drilling deep holes. Use appropriate personal protective equipment and clamp workpieces securely.
