Broca helicoidal para metal KWB 258632, 3,2 mm de diámetro, 65 mm de longitud

The KWB metal spiral drill bit with a 3.2 mm cutting diameter and 65 mm overall length is a straight-shank drilling tool intended for precise metalworking tasks. This drill bit is designed to create clean, accurate holes in steel, aluminium and other thin-walled metallic materials. Its geometry suits both hand-held and bench drills, enabling routine assembly, repair and workshop operations where consistent hole quality is required.

Advantages

The slim 3.2 mm diameter and 65 mm length provide access to confined spaces while maintaining rigidity for accurate drilling. The straight shank ensures secure gripping in standard chucks and the spiral flute efficiently evacuates chips to reduce clogging. The bit’s metal-cutting design gives predictable cutting behavior and long service life when used with correct speeds and cooling.

How to use

Secure the drill bit in the chuck of a hand-held drill or drill press, ensuring it is clamped straight and firmly. Select an appropriate drilling speed for the workpiece material (lower speeds for harder metals), apply steady axial pressure and maintain alignment with the intended hole. Use cutting fluid or coolant as needed to reduce heat, improve chip removal and extend bit life. Retract periodically for deep holes to clear chips and avoid clogging.

Recommendations

For best results, match drill speed and feed to the metal type, use a light cutting lubricant on steel, and avoid excessive side loading. Store the bit in a protective holder to keep the cutting edge sharp and inspect for wear or damage before each use.
