## Long description

Diamond Hole Saw Expert+ 45 mm with M14 shank is a cutting accessory engineered for creating precise 45 mm holes in hard surfaces. Compatible with angle grinders and rotary tools that accept an M14 threaded shank, this hole saw is suitable for work on ceramic, tile, glass and natural or engineered stone. The tool is designed for use up to a maximum speed of 12,000 rpm and can be applied in wet or dry drilling depending on the specific material and working conditions.
Advantages
The diamond-edged rim provides consistent cutting performance and extended service life when working with abrasive materials. A robust M14 threaded shank ensures secure mounting in compatible grinders and reduces wobble during operation. Rated for up to 12,000 rpm, the hole saw supports both high-speed and controlled-speed applications. Its 45 mm diameter delivers accurate hole sizing for plumbing fixtures, conduits and glazed fittings, while compatibility with wet or dry methods adds application flexibility.
Suitable for
Cutting 45 mm holes in ceramic tiles for plumbing and sanitary installations
Drilling through glass and mirror panels for fixtures and fittings
Creating openings in stone or engineered stone for anchors and pipes
Use with angle grinders and compatible rotary tools for renovation and construction tasks
Key specifications
Cutting diameter: 45 mm
Shank type: M14 threaded shank for direct mounting in compatible tools
Maximum rotational speed: 12,000 rpm
Cutting edge: diamond-segment rim suitable for hard and abrasive materials
Suitable drilling methods: wet or dry depending on material and application
How to use
Secure the diamond hole saw onto an angle grinder or rotary tool with an M14 thread, making sure the shank is tightened and the tool is unplugged or the battery removed during fitting. Mark the center of the intended hole and start drilling at low speed to establish a guide; then increase speed gradually up to, but not exceeding, 12,000 rpm. For tiles and glass, a light steady pressure and intermittent cutting help avoid cracking. When drilling stone or other dense materials, moderate pressure with consistent feed rate ensures efficient cutting. If using wet drilling, provide a steady supply of water to the cutting zone to reduce heat and extend blade life. If dry drilling, allow short pauses to avoid overheating the diamond segments.
Usage recommendations
Wear appropriate personal protective equipment including eye protection, gloves and respiratory protection when generating dust. Select wet drilling where possible for extended tool life and cleaner operation, and always observe the maximum speed rating and the tool manufacturer's instructions for the host machine.
