Spiralbor KWB 048700 1 stk. højreløbende

Twist drill bit KWB 048700 is a multi-material drill bit with tungsten carbide tips and diamond-ground cutting edges. The extra-hard Tungsten-Titanium-Carbide tips are high-temperature brazed for durability. The bit features an asymmetrical spiral and chip-removing flute geometry for efficient waste removal and reliable performance in rotary and impact drills. Copper-coloured ground surfaces make it suitable for work in masonry, marble, reconstituted stone, concrete, granite, brick, ceramics, various woods, plastics and acrylics, as well as alloyed and unalloyed steel, glass and crystal.

Advantages

The KWB 048700 offers long-lasting cutting performance due to its tungsten carbide-tipped, diamond-ground edges and high-temperature brazing. Its asymmetrical spiral improves chip evacuation which reduces clogging and increases drilling speed. The multi-material design allows one drill bit to be used across a wide range of materials, while the cylindrical shank ensures compatibility with standard chucks and holders.

Key specifications

How to use

Install the cylindrical shank into the drill chuck and tighten securely. Use the KWB 048700 with rotary or impact drilling modes as appropriate for the material. Start drilling at low speed to establish the hole, then increase speed while applying steady pressure. Periodically withdraw the bit to clear chips when drilling deep holes or dense materials. For glass or crystal, use light pressure and steady speed to avoid cracking.

Recommendations

Choose rotation and speed according to the material: lower speeds for hard materials (granite, ceramics, glass), medium speeds for concrete and stone, and higher speeds for wood and plastics. Use appropriate personal protective equipment, secure the workpiece, and allow the bit to cool between extended runs to preserve tip life.
