Drill bit Dedra DED1534 — 7 mm steel bit for glass and tile, 1 pc

Dedra DED1534 is a 7 mm steel drill bit designed for drilling clean, precise holes in glass and ceramic tile. The single-piece construction and geometry of the tip provide controlled cutting in fragile hard materials while remaining compatible with standard drill chucks. This bit is intended for tasks that require careful, accurate perforation where chipping and cracking must be minimised.

Advantages

The 7 mm diameter offers a balance between a compact hole size and sufficient clearance for many fasteners and fittings. Made of steel with a tip geometry optimised for glass and tile, the bit reduces the risk of surface damage and ensures more consistent hole shapes. Supplied as a single piece, it is simple to mount and use in a variety of handheld and bench drilling tools with standard chucks.

Suitable for

• Creating holes for fixtures in glass panes
• Drilling mounting points in ceramic wall and floor tiles
• DIY repairs involving fragile hard materials
• Installing glass fittings, handles and small brackets

How to use

Secure the workpiece and mark the drilling point. Fit the Dedra DED1534 7 mm bit into a drill with a standard chuck and set a low to moderate speed appropriate for glass or tile. Apply light, steady pressure and avoid lateral movement; allow the bit to penetrate gradually to prevent cracking. For ceramic tile, start at the glazed surface and keep the drill perpendicular. If necessary, use water or a lubricant recommended for tile drilling to reduce heat build-up and extend bit life.

Usage recommendations

Use protective eyewear and gloves when drilling glass or tile. Begin drilling with a starter technique—such as a small pilot mark or masking tape—if extra control is required. Do not use excessive force or high speed settings that can cause overheating or damage to brittle materials.
