Broca helicoidal KWB 048680 — 1 ud., giro a la derecha

KWB 048680 twist drill bit, single piece with right-hand rotation, is a multi-material drilling tool with tungsten carbide tipped cutting edges designed for use in rotary and impact drills. The bit features extra-hard Tungsten-Titanium-Carbide tips with diamond-ground cutting edges and high-temperature brazing. Its asymmetrical spiral and chip-removing geometry provide improved waste evacuation across a wide range of materials including masonry, stone, concrete, ceramics, wood, plastics and metals.

Advantages

The drill bit combines tungsten carbide tips and diamond-ground cutting edges for extended hardness and cutting precision. High-temperature brazing ensures secure tip attachment, while the asymmetrical spiral improves chip removal and reduces clogging. Ground surfaces and a copper-colour finish indicate precision machining and durability suitable for both rotary and impact drilling modes. Sold as a single replacement or spare piece for compatible drills.

Key specifications

How to use

Select an appropriate drill and clamping system for the bit shank, set the drill to right-hand rotation and the proper speed for the material. Secure the workpiece, mark the drilling point and start drilling with steady pressure. For harder materials (masonry, stone, concrete, ceramic) use impact or hammer function if supported by the drill; for metals, wood and plastics use rotary mode and adjust speed to the material. Withdraw the bit occasionally to clear chips and avoid overheating.

Recommendations

Use appropriate personal protective equipment (safety glasses, gloves, dust mask) and cooling or intermittent drilling when working in metal or dense stone. Match drill speed to material hardness to prolong tip life and avoid excessive force that can damage the tip or workpiece.
