## Summary description

Diamond core drill bit 30 mm by HOGERT, model HT7D285, designed for drilling precise 30 mm diameter holes in hard materials such as tile, ceramic, porcelain and stone. The diamond cutting edge ensures clean cuts and extended life. Suitable for use with rotary drills and drill stands for tasks in tiling, plumbing and electrical installations.

## Long description

The Diamond core drill bit 30 mm HOGERT HT7D285 is designed for drilling precise 30 mm diameter holes in hard surfaces such as tile, ceramic, porcelain and natural stone. Its diamond cutting edge provides efficient material removal and helps produce clean, chip-free holes with consistent diameter. The bit is intended for use with rotary drills and drill stands where controlled speed and steady feed deliver optimal results for installation and repair tasks.
Advantages
The diamond cutting segment delivers long life and maintains cutting performance in abrasive materials. A solid, rigid body helps minimize wobble and keeps hole tolerances accurate. The open segment design aids dust and slurry evacuation during wet drilling, reducing clogging and improving speed of cut. The 30 mm diameter is suited to common installation needs while the construction supports both handheld and stand-mounted operations.
Suitable for
Drilling holes in ceramic and porcelain tiles for plumbing and fixtures
Making service or access holes in natural stone and engineered stone
Installing electrical boxes or conduits through tiled walls
Creating openings for pipes and fittings in bathroom and kitchen renovations
Key specifications
Cutting diameter: 30 mm
Cutting material: diamond segment
Intended materials: tile, ceramic, porcelain, natural stone
Recommended drilling method: wet drilling for improved life and cooler cutting
Shank type: compatible with standard rotary drill chucks and drill stands
How to use
Secure the workpiece and, when possible, use a drill stand or guide to keep the bit perpendicular to the surface. Begin at low speed to establish a starting point, then proceed with moderate, steady pressure. For tile and stone, prefer wet drilling or continuous water feed to cool the diamond segment and remove slurry. Periodically withdraw the bit to clear debris and inspect the cutting edge. Do not apply excessive axial force; allow the diamond segment to cut at its designed rate.
Usage recommendations
Use appropriate personal protective equipment: safety glasses, gloves and dust protection. For best durability, perform most holes with water cooling, especially in dense or abrasive stone. Match drill speed and feed to the material—lower speeds for hard ceramics and stone, higher speeds for softer tiles. Inspect the bit before use and replace if diamond wear reduces cutting efficiency.
