GRAPHITE drill bit for glass and glaze, cylindrical carbide tip, 5 mm

GRAPHITE drill bit for glass and glaze, cylindrical carbide tip, 5 mm is designed for precise drilling in brittle materials such as annealed glass, ceramic tiles and glazed surfaces. The cylindrical carbide tip ensures focused cutting action and helps minimise chipping around the hole edge. The 5 mm diameter provides a balance between control and material removal, making the bit suitable for small through-holes and pilot holes in repair and installation tasks.

Advantages

The carbide tip maintains sharpness and abrasion resistance when working with hard, brittle surfaces. The cylindrical tip geometry delivers a stable cutting path and reduces the risk of cracking compared with standard twist bits. The 5 mm shaft is compatible with a wide range of drill chucks and supports both hand drills and drill presses. Overall design supports consistent hole size and improved finish in glazed and glass materials.

Suitable for

• Drilling holes in glass panels and panes for fixtures and fittings
• Creating openings in glazed ceramic tiles during installations or repairs
• Pilot holes for anchors or small fasteners in brittle surfaces
• Hobby and craft projects involving glass and glazed materials

Key specifications

• Diameter: 5 mm
• Tip material: carbide
• Tip geometry: cylindrical
• Recommended use: glass and glazed ceramics
• Shaft compatibility: standard drill chucks

How to use

Mark the drilling point and secure the workpiece to prevent movement. Start at low rotational speed and apply light, steady pressure; avoid forcing the bit to prevent cracking. For glass, consider introducing a small angle at the start or use a guide to maintain bit position. Use intermittent drilling with short breaks to allow debris removal and cooling. Finish the hole by easing pressure as the bit breaks through to minimise chipping.

Usage recommendations

Use a drill with adjustable speed and set a low RPM appropriate for brittle materials. Apply cutting lubricant or water to reduce heat and flush away glass or ceramic dust. Wear eye protection and secure the material on a padded, stable surface. For tempered glass, consult material specifications as drilling may not be possible.
