Broca KWB 048720 — broca helicoidal, giro a la derecha, 1 ud.

Drill bit KWB 048720 is a single twist drill bit with a cylindrical shank, designed for right-hand rotation and intended for use in most rotary and impact drills. The bit features tungsten carbide tipped, extra hard Tungsten‑Titanium‑Carbide tips with diamond-ground cutting edges and high-temperature brazing. Its asymmetrical spiral and chip-removing design support efficient waste evacuation across a wide range of materials, and it is finished in a copper colour with ground surfaces.

Advantages

The drill bit combines a tungsten‑carbide tip and diamond‑ground cutting edges for durable, precise cutting and improved wear resistance. High-temperature brazing ensures a secure tip-to-shank connection while the asymmetrical spiral enhances chip removal to reduce clogging during drilling. The cylindrical shank and standard twist geometry make the bit compatible with common chucks and suitable as a replacement or spare for general workshop and home use.

Key specifications

How to use

Fit the cylindrical shank into a compatible drill chuck and tighten securely. Select a suitable drill speed and apply steady pressure appropriate for the material being drilled. For masonry or concrete, use an impact function if available; for glass, ceramics or crystal, use low speed and steady feed with proper support to prevent cracking. Withdraw the bit periodically to clear chips when drilling deeper holes.

Recommendations

Use personal protective equipment (safety glasses and gloves) and clamp workpieces where possible. Match drill speed and feed rate to the material: higher speed for metals and plastics, lower speed with careful feed for stone, ceramic and glass. Replace the bit when cutting performance or edge quality decreases.
