Drill bit for glass and ceramic Heller QuickBit CeramicMaster model 8212630070

The Heller QuickBit CeramicMaster drill bit is designed for drilling glass and ceramic tile surfaces with controlled precision. Intended for use with standard hand drills and drill presses, this bit provides a focused cutting action suited to fragile, glazed materials. The geometry and tip design reduce chipping and help maintain the integrity of tiles and sanitary ceramics during hole-making for fixtures, anchors, and fittings.

Advantages

The drill bit offers a pointed tip geometry and a cutting edge shaped to start accurately on smooth, slippery surfaces without wandering. Its construction balances rigidity and controlled cutting to minimize cracking and glazing damage. Compatible with common drill speeds and pressures used in tile work, the bit supports repeatable hole quality for fitting screws, anchors, or plumbing fixtures.

Suitable for

• Drilling holes in glazed ceramic wall and floor tiles
• Making openings in sanitary ceramics for fixture mounting
• Cutting small holes in glass panels and mirrors for hardware
• DIY repairs and renovations that require precise holes in brittle surfaces

Key specifications

• Intended material: glass and ceramic tiles
• Compatibility: hand drills and drill presses
• Tip type: precision point for starting on smooth surfaces
• Use case: controlled cutting to reduce chipping and cracking
• Typical applications: tile installation, sanitary fixture mounting, mirror and glass hardware

How to use

Mark the drilling position and secure the tile or glass on a stable surface to prevent movement. Start drilling at low speed with light, steady pressure to allow the tip to create a reliable starter groove; increase speed moderately only after the bit has started cutting. Use water or a suitable coolant when drilling ceramic or glass to dissipate heat and flush dust. Avoid excessive lateral force and sudden impacts that can cause cracks; release pressure periodically to inspect progress and adjust as needed.

Usage recommendations

Use protective eyewear and gloves when drilling brittle materials. For best results, clamp or support the workpiece, keep the bit cool with continuous water flow, and use low to medium drill speeds. When drilling near edges, support the opposite side to reduce the risk of chipping.
