Electroplated diamond hole saws produce clean holes in glass, mirror, and tile when paired with proper technique and cooling.
Plumbers, glaziers, and tile installers drill holes for faucets, shower fixtures, and anchors in brittle materials that crack under impact. Carbide hole saws chip glass and glaze; electroplated diamond hole saws from Protec Tools expose sharp grit for controlled material removal without bond interference.
Material-Specific Approach
- Glass and mirror: Drill from the finished face with a guide jig and constant water cooling.
- Glazed ceramic: Start at low RPM through the glaze before increasing speed.
- Porcelain: Use a pilot guide plate; peck-drill through full thickness in stages.
Preventing Cracks and Blowout
Blowout occurs on the exit side when the bit breaks through. Place a sacrificial backer board behind the material and maintain light, consistent pressure throughout the cut.
Installer Checklist
- Select diameter including fixture clearance tolerance.
- Run at or below the manufacturer maximum RPM.
- Replace electroplated saws after 15–30 holes in porcelain.
- Keep separate saws for glass and tile to avoid cross-contamination.
Protec Tools electroplated hole saws are available in standard plumbing and electrical diameters with OEM packaging options.
