Broca helicoidal KWB 258645 giro a la derecha 1 ud.

HI-NOX HSS M2 spiral drill bit with right-hand cut and cylindrical shank, black/uncoated finish. The 130° point features a special polished section and the spiral has a polished "Quick Cut" geometry that produces small swarf. The design includes a reinforced core and spiral shoulder, a specially shaped short spiral notch and extra robust construction for optimal swarf removal and high heat resistance. The drill bit delivers optimal cutting performance particularly in all types of stainless steel and is also suitable for all steel types, cast iron and cast steel. It is designed for effortless, energy-saving drilling with cordless and tethered machines.

Advantages

The HI-NOX HSS M2 material and reinforced core provide durability and heat resistance during intensive drilling. The 130° polished point and "Quick Cut" spiral geometry reduce cutting forces and facilitate small, controlled swarf formation. The extra-robust construction and specially shaped short spiral notch improve chip evacuation and reduce the risk of breakage, enabling reliable performance in stainless steel, steels and cast materials.

How to use

Secure the cylindrical shank in the drill chuck and clamp firmly. Select a suitable drill speed and feed rate for the material being drilled (lower speeds for stainless steel and harder alloys). Use steady, moderate pressure and allow the drill to cut without excessive force. Withdraw the drill periodically for chip removal if necessary. For deeper holes, peck drilling or intermittent withdrawal helps maintain chip clearance and cooling.

Recommendations

When drilling stainless steel and other hard alloys, use cutting fluid or coolant to reduce heat and extend tool life. Start with a pilot hole for large diameters if appropriate, and avoid overheating by using appropriate speeds and intermittent drilling. Store the bit dry to prevent corrosion of the uncoated surface.
