Diamond-tipped trepanation drill bits set, Evolution EVO-WT-KPL-S3 — 3 short pieces

The Evolution Diamond-tipped trepanation drill bits set EVO-WT-KPL-S3 includes three short hole saw bits designed for precise circular cutting in brittle hard materials. Each bit features a diamond or abrasive cutting edge suited to tile, ceramics and glass. The compact short-shank design provides stable handling and improved control in confined spaces. These bits can be used with wet or dry cutting methods depending on the material and recommended drilling practice.

Advantages

The short shank configuration reduces overhang and increases rigidity for more accurate hole cutting. Diamond-tipped cutting edges deliver consistent performance on hard and brittle surfaces, reducing chipping when used correctly. The set format supplies multiple sizes for varied applications and replaces the need to buy individual bits. Durable construction supports repeated use when cutting conditions and cooling practices are appropriate.

Suitable for

• Drilling holes in ceramic wall and floor tiles
• Cutting circular openings in glass and glazed surfaces
• Creating clean holes in porcelain sanitaryware and vitrified materials
• Installation tasks in confined or recessed spaces where a short shank is needed

Key specifications

• Set composition: three short trepanation (hole saw) bits with diamond/abrasive cutting edges
• Shank type: compact short shank for controlled drilling in tight spaces
• Cutting method: suitable for wet or dry cutting depending on material and cooling
• Material compatibility: tile, ceramic, glass and similar brittle hard surfaces
• Application: circular hole cutting (trepanation) for installation and repair tasks

How to use

Select the appropriate bit size from the set and mount it in a compatible drill or driver with a suitable chuck or arbor. Position the bit at the drilling location, start at low speed to establish a guide point, and apply steady, moderate downward pressure. For brittle materials, consider starting at an angle briefly or using a guide to prevent slipping, then bring the drill to perpendicular. Use water or a coolant for wet cutting to reduce heat and dust when recommended for the material; for dry cutting follow manufacturer guidance and limit running time to avoid overheating. After cutting, clear debris from the hole and inspect the edge for chipping; finish edges as required.

Usage recommendations

For best results, secure workpieces, wear appropriate eye and respiratory protection, and use controlled speed with light pressure. Employ water cooling on tiles, ceramics and glass to extend diamond life and reduce chipping; when dry cutting, allow intermittent pauses to cool the bit. Avoid forcing the bit—let the diamond edge do the cutting to prolong service life.
