Vrták KWB 048630 1 ks pravotočivý

The KWB 048630 twist drill bit is a multi-material drill designed for right-hand rotation and versatile drilling tasks. It features tungsten carbide tips with extra-hard Tungsten-Titanium-Carbide, diamond-ground cutting edges and high-temperature brazing. The bit has an asymmetrical spiral and chip-removing geometry to support efficient waste removal and reliable cutting performance across a wide range of materials.

Advantages

Diamond-ground cutting edges and tungsten carbide tips deliver durable cutting performance and long life. High-temperature brazing secures the tip to the shank for increased strength. The asymmetrical spiral improves chip evacuation and reduces clogging during drilling. Ground surfaces and copper color finish add dimensional accuracy and resistance to wear. Suitable for both rotary and impact drills.

How to use

Fit the KWB 048630 twist drill bit into the drill chuck and secure it firmly. Select appropriate speed and drilling mode (rotary or impact) according to the material being drilled. Start drilling with steady pressure, allowing the asymmetrical spiral to evacuate chips. Withdraw periodically for deep holes to clear debris and avoid overheating. For glass or ceramic, use low speed and steady feed to avoid chipping.

Recommendations

Use suitable personal protective equipment (safety glasses, gloves) and clamp workpieces securely. Match drill speed and feed to the material: lower speeds for hard materials (glass, ceramics, granite), medium speeds for masonry and concrete, and higher speeds for wood and plastics. Replace the bit if cutting performance declines or tip damage is visible.
