Diamond hole saw for porcelain stoneware GRAPHITE 40 mm (57H291)

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.
