Diamond core drill bit HOGERT HT7D286 35 mm for drilling hard materials

The Diamond core drill bit HOGERT HT7D286 35 mm for drilling hard materials is a circular diamond-tipped bit designed for creating clean, accurate holes in tile, ceramic, glass and natural or engineered stone. It is intended for use with compatible rotary drills and drill rigs and delivers controlled cutting with reduced chipping on brittle surfaces. The 35 mm cutting diameter makes it suitable for installations and repair tasks that require precise circular openings.

Advantages

The diamond cutting edge provides high abrasion resistance and consistent performance when drilling hard, brittle materials. Segmented diamond segments or continuous rims (depending on application) help maintain cutting speed while minimizing surface damage. The core design allows extraction of a clean plug and straightforward hole finishing. Compatibility with common rotary drills and drill rigs offers flexibility for both professional and DIY use.

How to use

Secure the drill bit to a compatible rotary drill or drill rig according to the tool manufacturer's instructions. Mark the center of the hole on the workpiece. Begin drilling at low speed to establish the cutting position, then apply steady, moderate pressure and increase speed as appropriate for the material. For brittle surfaces such as glazed tile or glass, use a backing support if possible to reduce breakout. Cool the bit periodically with water or a suitable coolant to extend diamond life and reduce dust; follow safety guidance for wet or dry drilling as applicable.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses and gloves. When drilling hard or brittle materials, start with low speed and light pressure, maintain cooling to prevent overheating, and support the workpiece to minimize chipping. Verify that the drill's chuck and arbor are compatible and securely tightened before operation.
