Drill Bit Set KWB 044300 5 pcs Multi-purpose 3-8 mm

The KWB 044300 drill bit set contains five multi-purpose carbide-tipped bits with diameters 3, 4, 5, 6 and 8 mm. Designed to the ISO 5468 standard, these high-temperature brazed bits have laterally and vertically secured tungsten carbide plates and an asymmetrical chip-removing spiral profile. The set is intended for hammer-resistant drilling in concrete, masonry, natural and reconstituted stone, granite and limestone and is suitable for use in standard electric drills.

Advantages

Carbide tips brazed at high temperature and secured both laterally and vertically improve tip stability and lifetime. The asymmetrical ground spiral profile efficiently removes dust and debris from the hole. Chemical black finish reduces surface corrosion. The bits are produced to ISO 5468, offering consistent geometry for reliable performance in hammer and rotary drilling.

Suitable for

• Drilling holes in concrete and reinforced concrete (hammer mode)
• Masonry work: brick and block drilling
• Drilling into natural and reconstituted stone, including granite and limestone
• General purpose drilling with electric and hammer drills

How to use

Select the correct diameter for the required hole and mark the drilling point. Use an appropriate drill (standard electric drill or rotary hammer) and set it to hammer mode when working in concrete or masonry. Start drilling at low speed to establish the position, then apply steady pressure and increase speed as the bit enters the material. Periodically withdraw the bit to clear dust and allow cooling; for deep holes repeat this extraction to remove debris.

Usage recommendations

Use personal protective equipment (safety glasses, dust mask and hearing protection). Match drill type and mode to the material (use hammer function for concrete/masonry). Avoid excessive axial pressure and prolonged continuous drilling to prevent overheating; allow the bit to clear chips and cool between passes.
