## Long description

The Diamond hole saw Dedra H1240 92 x 75 mm is a circular cutting tool with a diamond edge designed for creating precise openings in hard surfaces. Intended for professional and DIY use, this hole saw is engineered to work with compatible drills and drill stands to produce clean, long-lasting holes in ceramic, porcelain, glazed tiles, natural stone and similar materials. Its diamond cutting segment provides abrasion resistance and maintains cutting performance when used with appropriate drilling technique and cooling.
Advantages
This hole saw delivers accurate circular cuts with minimal chipping on brittle materials due to the diamond cutting rim. The construction supports effective material removal and consistent hole diameter, helping to reduce rework. It is suitable for wet drilling which extends tool life and improves cutting speed when cooling and lubrication are applied. The tool fits standard arbor attachments used in drill setups, enabling straightforward replacement and compatibility with common drilling equipment.
Suitable for
Drilling holes for plumbing fixtures through ceramic and porcelain tiles
Creating openings for electrical boxes or conduit in tiled walls
Cutting precise holes in natural stone, marble and granite countertops (with appropriate drill setup)
Tile installation and repair work requiring clean circular cuts
Key specifications
Cutting diameter: 92 mm
Overall length / cutting depth: 75 mm
Cutting edge: diamond-segment rim for hard, brittle materials
Material compatibility: ceramic, glazed tiles, porcelain, natural stone and similar substrates
Intended use: handheld drills and drill stands with compatible arbors; suitable for wet drilling to reduce heat and wear
How to use
Mount the hole saw on a compatible arbor and secure it in the drill chuck following the drill and arbor manufacturer’s instructions. Mark the drilling point, start at low speed to establish the pilot contact, then increase speed as appropriate while maintaining steady pressure. For ceramic, porcelain and stone, use continuous cooling with water to keep the cutting edge cool and to remove debris; pause periodically to clear slurry if necessary. Maintain firm, even pressure without forcing the tool to avoid cracking or chipping the workpiece. After cutting, clean the hole and inspect edges before installing fixtures.
Usage recommendations
Use with a drill stand or guide when precise perpendicular holes are required. Operate with water cooling for longer life and better cutting performance. Select appropriate safety equipment such as eye protection, gloves and dust control.
