Diamond drill bit Smart SM-25-200 for porcelain, 20 mm

The Smart SM-25-200 diamond drill bit for porcelain, 20 mm, is designed for precision wet drilling of ceramic and porcelain tiles. The bit has a 20 mm cutting diameter and is intended for creating clean, accurately sized holes for fittings, pipes and fixtures when used with appropriate water cooling. It is compatible with standard drills that accept this type of diamond-tipped accessory and is intended for work where neat, chip-free holes in hard tile surfaces are required.

Advantages

This diamond drill bit provides precise, round holes in porcelain and ceramic tile thanks to its diamond cutting edge. Wet drilling with the Smart SM-25-200 reduces heat build-up and dust, which helps preserve the cutting edge and extends service life. The 20 mm diameter makes it suitable for many standard plumbing and installation openings while delivering smooth edges and minimal chipping when used correctly.

Suitable for

• Drilling holes in porcelain tiles for plumbing pipes
• Creating openings for fixtures and fittings in ceramic and porcelain surfaces
• Tile installation tasks requiring precise, clean holes

Key specifications

• Cutting diameter: 20 mm
• Intended material: porcelain and ceramic tiles
• Drilling method: wet drilling recommended
• Design: diamond cutting edge for hard tile materials

How to use

Secure the workpiece and mark the hole position. Use a standard drill compatible with diamond core bits and apply water cooling continuously during drilling to reduce heat and remove debris. Begin drilling at low to moderate speed, keeping the bit perpendicular to the tile surface; apply light, steady pressure and avoid forcing the bit. Once the hole is complete, withdraw the bit while the drill is running briefly to clear slurry, then stop and inspect the hole for clean edges.

Usage recommendations

For best results, use constant water flow and moderate drill speed, start with a guide or shallow pilot notch if needed to prevent slipping, and allow the bit to cool between extended cuts to prolong its service life.
