Drill bit Dedra DED1538, steel, diameter 1.4 cm, for glass and tile, 1 pc

Dedra DED1538 is a single steel drill bit with a 1.4 cm diameter designed specifically for drilling into glass and ceramic tile. The bit features a hardened metal construction and a tip profile intended to create precise, controlled holes in brittle surfaces. It is compatible with manual and powered drills and is suitable for tasks that require careful handling to avoid cracking or chipping of glazed or transparent materials.

Advantages

The steel construction offers durability and consistent cutting performance when working with glass and tile. The 1.4 cm diameter allows for larger-diameter holes without the need for multiple passes, while the tip geometry reduces lateral slipping and helps maintain placement accuracy. Supplied as a single piece, this drill bit is easy to store and replace in common drill chucks.

Suitable for

• Drilling holes in ceramic wall and floor tiles
• Creating openings in glass panes and mirrors (with appropriate support)
• Installing bathroom fixtures such as towel rails and soap holders in tiled surfaces
• Small DIY projects requiring precise holes in brittle materials

Key specifications

• Material: steel
• Drill bit diameter: 1.4 cm
• Intended materials: glass, ceramic tile
• Quantity: 1 piece
• Compatibility: designed for use with manual and powered drills

How to use

Secure the workpiece to prevent movement and, for glass, provide backing support to reduce the risk of cracking. Fit the Dedra DED1538 drill bit into the drill chuck, ensuring it is tightly clamped and centered. Use a low to moderate rotational speed and apply steady light pressure; avoid excessive force or high speeds which can overheat the bit or damage the material. For glass and glossy tiles, consider using water as a coolant and lubricant to reduce heat buildup and to help clear debris from the hole. After drilling, inspect the hole edges and remove any loose fragments carefully.

Usage recommendations

For best results, mark the drilling point clearly, use a guide or masking tape to help prevent the bit from wandering, and operate the drill at low speed with constant cooling when working with glass or porcelain tiles. Wear eye protection and take care to support fragile pieces to avoid breakage.
