Borenset KWB 258806 6 stuks rechtsdraaiend

HI-NOX HSS M2 spiral drill, 130° point angle, right-hand cut, cylindrical shank, black/uncoated finish with a special polished section and "Quick Cut" geometry designed for producing small swarf. The drill features a reinforced core, strengthened spiral shoulder and a specially shaped short spiral notch for improved swarf evacuation. It is extra robust and extremely heat-resistant, providing optimal cutting performance especially in stainless steel, and is also suitable for all steel types, cast iron and cast steel. Designed for effortless and energy-saving drilling with cordless or tethered machines. Supplied as a set of 6 right-hand rotation bits (KWB 258806).

Advantages

The HI-NOX HSS M2 construction combines a reinforced core and polished spiral sections to increase tool life and stability. "Quick Cut" geometry reduces chip size for smoother drilling and improved evacuation. The 130° point angle and polished tip support precise centring and reduced axial thrust, while the high heat resistance maintains cutting performance at elevated temperatures. The cylindrical shank and robust build make the bits compatible with both cordless and corded drills.

How to use

Select the appropriate drill bit size for the task and secure it in the drill chuck with the cylindrical shank fully seated. Mark the drilling point and, if needed, use a centre punch for accurate starting. Start drilling at low speed to establish the hole, then increase speed according to material and bit size. Apply steady, even pressure and allow the drill to remove chips; do not force the bit. For stainless steel and other tough materials, use moderate cutting speed and consistent coolant or cutting lubricant to extend bit life and reduce heat build-up.

Recommendations

For best results in stainless steel and harder alloys, use cutting fluid, moderate speeds and intermittent pecking to clear chips. Store the set in a dry place and inspect bits before use for signs of wear or damage.
