## Summary description

GRAPHITE cylindrical carbide drill bit designed for drilling glass and ceramic glaze. Diameter 8 mm; solid carbide tip suited for brittle materials; cylindrical shank for standard chucks. Intended for precise through-holes and clean edges in glass tiles, glazed ceramics and similar brittle surfaces. Use with low speed, steady pressure and cooling or lubrication as recommended for brittle materials.

## Long description

GRAPHITE cylindrical carbide drill bit 8 mm is designed for drilling glass and glazed ceramics. The solid carbide tip and specific geometry are suited to brittle materials, enabling precise through-holes and smooth edges in glass tiles, glazed sanitaryware and other similar surfaces. The cylindrical shank fits standard chucks and allows stable clamping for hand-held and bench drills. For best results, use low rotational speeds, steady feed pressure and appropriate cooling or lubrication to reduce heat and prevent chipping.
Advantages
The solid carbide tip provides high hardness and wear resistance required for cutting brittle materials without rapid dulling. Cylindrical shank ensures compatibility with most drill chucks and stable concentricity during drilling. The tip geometry is optimised to minimise cracking and produce cleaner hole edges in glass and glaze. Available in an 8 mm diameter for medium-size holes commonly needed for fittings and fixtures.
Suitable for
 Drilling holes in glass tiles and glass panels
 Creating through-holes in glazed ceramic tiles and sanitaryware
 Precise installation holes for fittings in bathrooms and kitchens
 Workshop and renovation tasks involving brittle surfaces
Key specifications
 Diameter: 8 mm
 Tip material: solid carbide
 Shank type: cylindrical (straight) shank
 Intended materials: glass, glazed ceramics and similar brittle surfaces
 Typical use: through-holes with clean edges
How to use
Mark the drilling position and secure the workpiece to prevent movement. Start drilling at low speed with steady, moderate pressure; do not apply excessive force. Use cooling or lubrication, such as water, to reduce heat and wash away debris; intermittent drilling can help control temperature and avoid overheating. If possible, support the underside of the glass or tile to reduce the risk of cracking when breaking through. After drilling, clean the hole to remove any residue and inspect edges for chipping.
Usage recommendations
Use a drill with adjustable speed and a secure clamping system. Avoid high speeds and heavy feed rates—slow rotation and gentle pressure extend tool life and improve hole quality in glass and glaze. Always wear appropriate eye protection and follow safety guidance when working with brittle materials.
