## Summary description

The KWB 052800 drill bit set includes 4 pieces with sizes 5mm, 6mm, 8mm, and 10mm. Designed for right-hand rotation, these bits are perfect for various drilling tasks, ensuring precision and durability. Ideal for both professionals and DIY enthusiasts.

## Long description

The KWB 052800 drill bit set contains four diamond-cut special carbide bits in sizes 5 mm, 6 mm, 8 mm and 10 mm. Each bit has a high tungsten carbide content with a homogeneous, fine-grained structure and a 120° tip angle. The bits are asymmetrically spiraled to optimise removal of dry drill cuttings and are finished in green. They are designed for right-hand rotation and recommended for use without impact at 800–1,000 rpm. Suitable for battery-powered and corded machines.
Advantages
Diamond-cut carbide edges and a high proportion of tungsten carbide provide increased wear resistance and maintain sharpness when drilling very hard materials. The asymmetrical spiral improves chip evacuation during dry drilling, reducing clogging. The 120° tip angle and high contact pressure ensure precise centring and efficient cutting in dense stone and masonry. A compact set of four sizes covers common hole diameters for demanding applications.
Suitable for
Granite and gneiss
Slate and basalt
Concrete and masonry
Glass and ceramics
Roof tiles and other hard materials
Key specifications
Set contents: 4 pcs — 5 mm, 6 mm, 8 mm, 10 mm
Tip angle: 120°
Material: diamond-cut special carbide with high tungsten carbide content
Spiral: asymmetrical for dry chip transport

How to use
Choose the appropriate drill bit size for the required hole and secure it in the drill chuck for right-hand rotation. Set the drill to a non-impact mode and start at low speed to establish a centre, then increase to the recommended 800–1,000 rpm. Apply steady axial pressure; the bits are designed for high contact pressure. Use dry drilling and periodically withdraw the bit to clear cuttings if necessary.
Usage recommendations
For best results, avoid impact or hammer mode, maintain the recommended rotational speed, and allow the drill bit to cool by intermittent drilling. Use suitable personal protective equipment (eye and hand protection) when working with stone, ceramics or glass.
