Drill bit 6 mm Dedra DED1571 — steel bit for stone, terracotta, glass, ceramic

Dedra DED1571 drill bit, 6 mm diameter, is a single-piece steel bit designed for drilling precise holes in hard, brittle materials such as stone, terracotta, glass and ceramic. Manufactured for use with compatible drills and rotary tools, this 6 mm steel bit offers a compact solution for tasks in construction, tiling, glazing and small repair jobs where accuracy and a clean hole edge are required.

Advantages

The Dedra DED1571 6 mm steel drill bit provides consistent hole quality in brittle materials thanks to its tough single-piece construction that reduces wobble during operation. Its 6 mm diameter is suitable for common fixing and fastening needs, and the bit’s material compatibility—stone, terracotta, glass and ceramic—makes it a versatile choice for specialist applications. The compact, single-piece design simplifies handling and installation into compatible chucks.

Suitable for

• Drilling holes for wall anchors in terracotta and masonry tiles
• Creating openings for fittings in ceramic tiles and sanitary ware
• Making precise holes in glass for glazing and fixtures (with appropriate drill speed and cooling)
• Small construction and repair tasks that require a 6 mm hole in brittle materials

Key specifications

• Diameter: 6 mm
• Material compatibility: stone, terracotta, glass, ceramic
• Quantity: 1 piece
• Construction: single-piece steel bit for use with standard drill chucks and rotary tools

How to use

Fit the Dedra DED1571 6 mm bit securely into a compatible drill chuck, ensuring proper tightening to minimize runout. Select a low to moderate drilling speed appropriate for brittle materials and, where applicable, use light pressure to avoid cracking. For glass and glazed ceramic, use slow speed and intermittent cooling or lubrication to reduce heat build-up. Begin drilling with a steady, controlled motion; avoid sudden force or lateral movement. After drilling, clear debris from the hole and inspect edges for chipping.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. When working with glass or glazed surfaces, secure the workpiece and consider using masking tape over the drill point to help prevent splintering. If drilling into masonry, start with a pilot mark and consider a low-speed, percussion-free approach to maintain bit integrity and hole quality.
