## Summary description

Diamond hole saw GRAPHITE model 57H291, Ø 40 mm, designed for drilling precise holes in porcelain stoneware (gres). The tool features a diamond cutting edge for effective material removal and durability when cutting hard ceramic and stone-based tiles. Suited for installing fittings, pipes and cable passages in tile surfaces with rotary or drill press use and appropriate cooling.

## Long description

Diamond hole saw GRAPHITE 40 mm is designed for precise drilling in porcelain stoneware (gres). The tool features a continuous diamond cutting edge that enables efficient material removal on hard ceramic and stone-based tiles. It is intended for use with rotary drills and drill presses when making holes for fittings, pipes and cable passages in tiled surfaces and should be used with appropriate cooling to extend service life.
Advantages
The reinforced diamond cutting rim provides durable performance when cutting abrasive and hard glazed surfaces, while the solid steel body ensures stability and accurate hole geometry. The tool’s 40 mm diameter offers a balance between hole size needed for common plumbing and electrical fittings and control during drilling. When used with water or coolant and a steady drilling speed, the hole saw resists glazing and chipping for cleaner edges.
Suitable for
Drilling through porcelain stoneware (gres) and hard ceramic tiles
Creating holes for plumbing fittings and pipe penetrations
Making cable and conduit passages in tiled walls and floors
Use with handheld rotary drills or drill presses with appropriate cooling
Key specifications
Cutting diameter: 40 mm
Cutting edge: diamond continuous rim
Body material: steel
Recommended materials: porcelain stoneware (gres), hard ceramic, stone-based tiles
Intended mounting: compatible with standard drill arbors for hole saws
How to use
Secure the hole saw to a suitable arbor and mount it in a rotary drill or drill press. Mark the drilling location on the tile and begin at low speed to establish the cutting position. Apply light, steady pressure and maintain continuous cooling with water or a coolant to reduce heat and remove debris. Increase speed moderately only when the cutting rim engages evenly; avoid excessive torque or side pressure to prevent tile cracking. After cutting, withdraw the tool periodically to clear slurry and inspect the hole for completeness.
Usage recommendations
Use a drill with adjustable speed and consistent water cooling for best results; for large or thick tiles consider a drill press to maintain perpendicular alignment and reduce the risk of chipping.
