Diamond Hole Saw for Porcelain Gres 83 mm GRAPHITE 57H299

Diamond Hole Saw for Porcelain Gres 83 mm GRAPHITE 57H299 is a drilling accessory designed for creating precise circular openings in hard tile materials such as porcelain and gres. The tool features an 83 mm cutting diameter and a diamond-segmented rim that enables controlled removal of tile material while minimising chipping when used with correct technique and adequate cooling. It is intended for use with compatible power drills and core drill holders for bathroom, kitchen and façade tiling tasks where clean pipe, fitting or cable pass-through holes are required.

Advantages

The diamond cutting edge provides high abrasion resistance and consistent cutting performance on dense ceramics. The 83 mm diameter matches common plumbing and conduit sizes, reducing the need for additional trimming. When operated with water cooling and steady feed, the hole saw maintains its shape and delivers smooth hole walls, which simplifies sealing and fixture installation. The design promotes efficient debris removal and stable steering during drilling.

Suitable for

• Drilling circular openings for pipes and fittings in porcelain and gres tiles
• Creating access holes for taps and shower fixtures during bathroom installation
• Making cable pass-throughs and service penetrations in tiled kitchen walls

Key specifications

• Cutting diameter: 83 mm
• Cutting material: diamond-segmented rim suitable for hard ceramics
• Intended materials: porcelain, gres and other dense ceramic tiles
• Recommended use with water cooling to reduce heat and extend tool life
• Compatible with standard core-drill arbors and rotary drills capable of controlled feed

How to use

Mark the center point on the tile and secure the workpiece to prevent movement. Start drilling at low speed to establish the cut, then increase to a moderate, steady speed while applying light, even pressure. Use continuous or intermittent water cooling to keep the diamond rim cool and to wash out debris; avoid dry high-speed drilling as this can overheat the segments and reduce life. If drilling through already-installed tiles, back the drill spindle out periodically to clear swarf and maintain visibility. After completing the hole, clean the edge and check for any minor chipping before fitting pipes or fixtures.

Usage recommendations

For best results, use with a drill that allows variable speed control and pair the hole saw with a proper core-drill arbor. Maintain steady feed, adequate cooling and avoid excessive lateral force. When drilling large-diameter holes in very hard gres, consider starting with a small pilot hole or using a guide to improve centring and reduce the risk of tile damage.
