Diamond drill bit for porcelain stoneware Smart 10 mm SM-25-100

Diamond drill bit Smart 10 mm SM-25-100 is designed for drilling precise holes in porcelain stoneware (gres). The 10 mm cutting diameter and a diamond cutting edge provide effective material removal and clean edges on hard glazed and dense ceramic surfaces. This drill bit is intended for use with rotary drills or drill presses when fitted with the appropriate adapter and cooling/low-speed technique to reduce wear and prevent damage to the workpiece.

Advantages

The diamond-edged tip ensures accurate, clean holes with minimal chipping on porcelain stoneware and other hard ceramics. Its robust construction resists wear during repeated use, while the 10 mm diameter offers a standard size for common fixtures and fittings. The bit performs reliably on glazed and dense surfaces where standard masonry bits would struggle, providing improved lifespan and more consistent results when used with correct cooling and feed rate.

Suitable for

• Drilling holes for plumbing penetrations in tiled walls
• Creating openings for fixtures such as anchors or sleeves in porcelain tiles
• Installing electrical boxes or conduits through ceramic surfaces
• Tile installation and renovation projects requiring precise small-diameter holes

Key specifications

• Cutting diameter: 10 mm
• Cutting edge: diamond-segment tip for hard ceramics
• Material compatibility: porcelain stoneware (gres), glazed ceramics
• Recommended tool types: rotary drill or drill press with suitable adapter
• Preferred drilling mode: low speed with coolant or intermittent feed to control heat

How to use

Mark the drilling position and secure the tile or workpiece to prevent movement. Start drilling at low speed and maintain a steady, moderate pressure without forcing the bit. Use water as coolant or periodically lift the bit to allow cooling; this reduces heat build-up and extends the diamond segment life. If using a handheld drill, consider a guide or template to keep the bit perpendicular to the surface. Finish the hole with gradual feed to avoid chipping the glazed surface.

Usage recommendations

Use low to moderate rotational speed, constant water cooling or intermittent wetting, and minimal axial pressure to maximize cutting performance and tool life. Select an appropriate adapter or chuck that ensures a secure fit and alignment between the drill and bit.
