Broca helicoidal KWB 258710 giro a la derecha 1 ud.

HI-NOX HSS M2 spiral drill bit, sharpened with right-hand cut and cylindrical shank, designed for efficient drilling in stainless steel, other steels, cast iron and cast steel. The bit has a 130° point angle with a special polished section and a polished spiral with "Quick Cut" geometry for producing small swarf. Reinforced core, strengthened spiral shoulder and a specially shaped short spiral notch make the drill extra robust and improve chip evacuation. The black/uncoated finish and high heat resistance support reliable performance when used with cordless or mains-powered drilling machines. The product corresponds to the KWB 258710 model and is supplied as a single piece.

Advantages

The drill bit offers optimized chip removal thanks to its Quick Cut spiral geometry and polished sections, delivering consistent cutting performance in stainless steels and other ferrous materials. A reinforced core and robust spiral shoulder increase durability and resistance to breakage under load. The 130° point angle and sharpened tip ensure easy penetration and reduced thrust force, which helps energy-efficient drilling with both cordless and corded machines.

How to use

Secure the drill bit in the drill chuck, ensuring the cylindrical shank is clamped firmly and runout is minimal. Select a suitable drill speed for the material (lower speeds for stainless steel and cast iron). Use cutting fluid when drilling stainless steel to reduce heat and improve chip evacuation. Apply steady moderate feed pressure; the 130° point and sharpened tip reduce required thrust. Clear chips regularly to avoid clogging the spiral notch.
