Drill bit set KWB 44800 — 4 pcs, sizes 5, 6, 8, 10 mm, right-hand rotation

KWB 44800 is a 4-piece drill bit set with right-hand rotation, supplied in a blister pack and including diameters 5, 6, 8 and 10 mm. The set is intended for general drilling tasks and presents a compact selection of common sizes for use with compatible electric drills. The bits are suitable for drilling into a range of materials when matched with the correct bit type and drill settings.

Advantages

The drill bits in this set feature tungsten carbide tips that are high-temperature brazed and secured both laterally and vertically for improved tip stability. An asymmetrical spiral profile promotes efficient chip removal, while the ground spiral and chemical black finish reduce friction and support durability under load. These characteristics make the bits hammer-resistant and suitable for demanding drilling into hard mineral materials when used with appropriate drill modes.

Suitable for

• Drilling into concrete and masonry
• Work on granite, natural and reconstituted stone
• Punching holes in limestone and similar mineral substrates
• General purpose drilling where right-hand rotation is required

Key specifications

• Set size: 4 pieces — 5 mm, 6 mm, 8 mm, 10 mm
• Tip material: tungsten carbide tipped
• Tip joining: high-temperature brazed
• Tip fixation: laterally and vertically secured carbide plates
• Spiral: asymmetrical profile with ground flutes for chip removal
• Finish: chemical black
• Compatibility: suitable for electric drills with right-hand rotation and hammer function where applicable

How to use

Select the drill bit size appropriate for the task and secure it in the drill chuck according to the drill manufacturer’s instructions. Use right-hand rotation and set the drill mode suitable for the material: rotary mode for softer substrates, rotary hammer mode for concrete or masonry. Apply steady pressure, allow the bit to remove material and withdraw periodically to clear chips. Maintain correct drill speed and coolant or intermittent operation when recommended for the substrate and drill type.

Usage recommendations

Use the bits with compatible drills and correct operating modes. Start with a pilot hole for large diameters, use appropriate safety equipment, and replace worn or damaged bits to maintain drilling performance and safety.
