Drill bit Dedra DED1536 — Ø 1 cm, steel, for glass and tile, 1 pc

Dedra DED1536 is a 1 cm diameter steel drill bit designed for controlled drilling in glass and ceramic tile surfaces. Supplied as a single piece, this drill bit is intended for use in installation and repair tasks where precise hole sizing and careful material handling are required. The tool is compatible with standard rotary drills when used at appropriate speeds and with coolant or water to minimise heat build-up and reduce the risk of cracking in brittle materials.

Advantages

The steel construction provides durability and consistent shaping to maintain a steady cutting edge during repeated use on hard-surfaced materials. The 1 cm cutting diameter ensures accurate, standardised hole size for fixtures and fittings. Designed specifically for glass and tile, the geometry and material of the bit reduce chipping when used correctly with slow rotation and cooling. Supplied as a single unit, it is convenient for occasional repairs or as a replacement tool.

Suitable for (tasks / use cases)

• Drilling holes in glass panes for fittings or decorative elements
• Creating openings in ceramic or porcelain tiles during bathroom and kitchen installations
• Repair work where precise, clean holes in brittle surfaces are required
• Preparing mounting points for anchors, screws or small fixtures in tiled walls

Key specifications

• Material: Steel cutting body suitable for hard, brittle surfaces
• Diameter: 1 cm cutting diameter for consistent hole sizing
• Intended materials: Glass and ceramic tile
• Quantity: Single drill bit per package

How to use

Secure the workpiece to prevent movement and mark the drilling point. Use a rotary drill with adjustable speed; begin at low RPM to create a shallow guide and then increase slightly while keeping speed moderate. Apply a steady flow of water or coolant to the drilling area to dissipate heat and lubricate the cutting surface. Use light, even pressure—do not force the bit—to avoid cracking or chipping. After drilling, clean the hole and inspect the edges for any imperfections before fitting fixtures.

Usage recommendations

For best results when drilling glass and tile, use low to moderate drill speeds, continuous cooling (water), and minimal axial pressure. Wear eye protection and gloves, clamp or stabilise the workpiece, and practice on scrap material if uncertain about technique. Replace the bit if excessive wear or chipping of the cutting edge is observed.
