Diamond Hole Saw Lenox 35 mm – core drill bit for ceramics and tiles

Diamond Hole Saw Lenox 35 mm is a specialist core drill bit designed for creating clean, circular holes in hard surfaces. With a 35 mm cutting diameter and diamond-segmented edge, this hole saw is intended for use on ceramics, porcelain, ceramic tiles and similar stone-based materials. It is suitable for wet drilling setups to reduce heat and dust, and to ensure precise core removal for plumbing, electrical fittings and fixture installation tasks.

Advantages

The diamond cutting edge provides efficient material removal and long life when used on hard glazed and unglazed tiles. Its 35 mm diameter gives a standard size for common plumbing and electrical pass-throughs, while the core drill design reduces chipping and delivers smooth hole edges. Compatibility with wet drilling helps maintain performance by cooling the cutting segments and minimizing dust during operation.

Suitable for

• Drilling holes for plumbing pipes and fittings in ceramic and porcelain tiles
• Creating openings for electrical conduits and fixture mounting in tiled surfaces
• Cutting circular holes for ventilation or drainage outlets in stone-based tiles

Key specifications

• Cutting diameter: 35 mm
• Cutting material: diamond-segmented edge suitable for hard tiles
• Recommended drilling method: wet drilling to reduce heat and dust
• Intended materials: ceramics, porcelain, glazed and unglazed tiles, similar stone-based surfaces
• Design: core hole saw for clean core removal and reduced chipping

How to use

Secure the workpiece and mark the hole centre. Fit the hole saw to a suitable mandrel or arbor compatible with the drilling machine, and set up a steady wet feed (water cooling) to the cutting area. Start drilling at low speed to establish the pilot, then apply steady pressure and moderate speed while keeping the cutting edge cooled. Remove the core periodically if required to prevent clogging and inspect the hole edge for chipping. Follow the drill and tool manufacturer recommendations for speed and feed ranges.

Usage recommendations

Use with appropriate personal protective equipment (safety glasses, gloves) and a drill capable of stable torque. Prefer wet drilling to extend tool life and improve hole quality. Avoid excessive side load and overheating; allow the tool to cool between long runs. Test on a scrap tile if unsure about speed or pressure settings for a specific material.
