Glass and Tile Drill Bit Heller QuickBit CeramicMaster 8212630030

Heller QuickBit CeramicMaster 8212630030 is a drill bit engineered for making precise holes in glass and ceramic tiles. Designed to work with handheld drills, this bit produces clean edges and minimizes chipping when used with appropriate drilling speed and steady technique. It is suitable for installation, plumbing, tiling and craft applications where controlled, accurate perforation of brittle surfaces is required.

Advantages

The drill bit features a ground tip profile and a hardened cutting edge that help initiate drilling on smooth, non-porous surfaces without excessive slipping. Its geometry reduces radial stress during penetration, which lowers the risk of cracking and chipping around the hole. The bit is compatible with standard drill chucks and is intended for use at recommended speeds for brittle materials, allowing reliable performance in manual drilling tasks.

Suitable for

• Drilling holes in ceramic wall and floor tiles
• Making openings in glass panes for fixtures and fittings
• Plumbing and sanitary installations requiring tile penetrations
• DIY and craft projects involving fragile materials

Key specifications

• Designed for use on glass and ceramic tile materials
• Shank compatible with standard handheld drill chucks
• Ground tip geometry for reduced slipping on smooth surfaces
• Hardened cutting edge to improve durability during tile drilling
• Intended for manual drilling at controlled speeds suited to brittle substrates

How to use

Mark the drilling position on the tile or glass and secure the workpiece to prevent movement. Start drilling at a low speed and apply light, steady pressure to allow the tip to score the surface before increasing speed slightly if needed. Keep the drill perpendicular to the surface to maintain a clean, round hole. For larger diameters, use progressive drilling or appropriate pilot steps to avoid excessive stress. If drilling through glazed tiles, reduce speed and pressure near the finish side to prevent blowout.

Usage recommendations

Use water or a suitable coolant to reduce heat buildup when drilling extended holes; avoid excessive lateral force and do not use impact/drill hammer modes. Always wear eye protection and secure tiles or glass to prevent slipping. Test on a scrap piece when possible to establish optimal speed and pressure for the specific material and thickness.
