Dedra DED1535 is an 8 mm steel drill bit designed specifically for drilling clean, accurate holes in glass and ceramic tile. Supplied as a single piece, this specialty bit fits standard manual and powered drills and is intended for tasks that require controlled penetration of brittle surfaces without excessive chipping or cracking.

Advantages

The steel construction provides durability and consistent performance on hard, brittle materials. The 8 mm diameter offers a balance between strength and precision, enabling stable drilling while minimizing material stress. As a single-piece supply, the bit is ready for immediate use and easy to replace when worn.

Suitable for

• Drilling holes in glass panes for fittings or fixtures
• Making openings in ceramic wall and floor tiles for plumbing or electrical installations
• Creating precise holes for decorative hardware on tiled surfaces

Key specifications

• Diameter: 8 mm
• Material: steel
• Intended materials: glass, ceramic tile
• Quantity: 1 piece

How to use

Mark the drilling point and secure the workpiece to prevent movement. Start drilling at low speed, applying steady, light pressure to avoid cracking the glass or tile. If possible, use a backing support beneath the tile or glass edge to reduce exit chipping. For tiled surfaces, consider starting with a small pilot mark or using masking tape to help stabilize the bit. Periodically withdraw the bit to clear debris and allow cooling.

Usage recommendations

Use with a drill that allows speed control and consider water cooling or intermittent drilling when working on large or heat-sensitive tiles. Wear safety goggles and gloves, secure the workpiece, and avoid excessive side pressure to maintain bit life and prevent material damage.
