Diamond drill bit Distar 17982091081, 8 mm diameter, for hard materials

Diamond drill bit Distar 17982091081 with an 8 mm diameter is designed for drilling hard materials. The tool features a diamond cutting edge that provides increased wear resistance and efficient penetration in materials such as concrete, natural stone and ceramic. It is intended for use with rotary drills and hammer drills where diamond tooling is required, delivering precise round holes and longer service life compared with standard carbide bits.

Advantages

The diamond cutting edge ensures consistent cutting performance and improved durability when working with dense, abrasive materials. The 8 mm diameter gives a compact size for precise holes while maintaining structural rigidity during drilling. Compatibility with common drill types allows straightforward use on-site or in workshop environments. The design reduces frequent bit changes and supports steady drilling speed and hole quality in demanding materials.

Suitable for

• Drilling holes in concrete and reinforced concrete (small diameter openings)
• Drilling natural and engineered stone
• Creating holes in ceramic tiles and porcelain
• Tasks requiring precise small-diameter holes with extended tool life

Key specifications

• Diameter: 8 mm
• Cutting material: diamond cutting edge
• Intended materials: concrete, stone, ceramic
• Tool compatibility: rotary drills and hammer drills suitable for diamond bits
• Primary application: drilling of hard and abrasive materials

How to use

Mount the drill bit securely in the drill chuck following the drill manufacturer's instructions. Use steady, moderate feed pressure and avoid excessive side load to preserve the diamond cutting edge. For best results when drilling dense materials, use water cooling or periodic withdrawal to reduce heat and clear debris if the bit and drill setup allow. Begin drilling at low speed to establish the hole, then adjust speed according to material hardness and drill capability. Keep the drill aligned perpendicular to the work surface to achieve a precise round hole.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. When drilling tiles or porcelain, place masking tape over the drilling point to reduce chipping. For reinforced concrete, proceed carefully to avoid overload; if encountering heavy steel reinforcement, stop and reassess with suitable rebar-cutting tools. Store the bit in a dry place and inspect the diamond edge before use to ensure consistent performance.
