Electroplated Diamond Drill Bits for Porcelain Tile and Glass Openings

How electroplated diamond drill bits help create clean holes in porcelain tile and glass.

Electroplated diamond drill bits carry a single diamond layer on a steel tube, giving a sharp cutting edge for porcelain tile, glass and similar brittle sheets. Protec Tools supplies electroplated diamond drill bits for installers and OEM brands that need clean openings with controlled chipping.

Best-Fit Applications

Porcelain and ceramic tile plumbing openings
Glass and mirror hole cutting with proper cooling
Thin hard materials where sintered bits feel too aggressive
Handheld or drill-press work with light feed pressure

Operating Tips for Buyers

Start at a low angle or use a guide to prevent skating.
Use water or approved coolant to clear debris.
Avoid heavy feed that strips the diamond layer early.
Match bit diameter and shank to the drill chuck.

Electroplated bits are not always the longest-life option on thick reinforced materials, but they excel when edge quality matters. Importers should specify diameter range, shank type, wet or dry preference and target materials when requesting private-label production.
