Diamond Hole Saw Expert+ 12 mm, M14 shank, max 12,000 rpm

Diamond Hole Saw Expert+ 12 mm with an M14 shank is a compact cutting accessory designed for drilling precise round holes up to 12 mm in diameter in hard surfaces such as tile, ceramic, glass and thin stone. Intended for use with angle grinders and rotary tools that accept an M14 arbor, this hole saw supports high-speed operation up to 12,000 rpm and is suitable for renovation, tiling and installation tasks where clean, accurate holes are required.

Advantages

The diamond cutting edge provides fast, consistent cutting performance and extended life when used on abrasive materials. The M14 threaded shank ensures secure mounting to compatible angle grinders and rotary tools. Its small 12 mm diameter is ideal for creating neat openings for pipes, cables, anchors and fixture fastenings while minimizing material waste and the risk of cracking surrounding tiles.

Suitable for

• Drilling holes in ceramic and porcelain tiles
• Creating openings in glass panels and thin stone
• Installing plumbing and electrical fixtures where small-diameter holes are needed
• Renovation and tiling jobs using angle grinders or rotary tools with M14 arbor

Key specifications

How to use

Mark the hole position and secure the workpiece to prevent movement. Attach the diamond hole saw to a compatible tool with an M14 arbor and tighten according to the tool manufacturer’s instructions. Begin drilling at low speed to establish the cutting position, then increase speed up to the recommended maximum while maintaining steady, even pressure. Use water cooling or periodic pauses to reduce heat build-up and prolong the life of the diamond rim, and stop occasionally to clear debris from the cutting area.

Usage recommendations

For best results, use light to moderate pressure, keep the cutting area wet when possible to reduce dust and heat, and avoid forcing the tool. Wear appropriate personal protective equipment including eye protection, gloves and a dust mask. Verify tool compatibility with an M14 shank before use and follow the safety instructions of the angle grinder or rotary tool.
