Drill bit Dedra DED1530 — 3 mm, steel, for glass and tile, 1 pc

Dedra DED1530 drill bit, 3 mm diameter, is a single-piece steel bit engineered for drilling small, precise holes in glass and ceramic tile. Designed for use on hard brittle materials where controlled penetration and minimal chipping are required, this drill bit fits standard rotary drills and is intended for applications where a narrow-diameter hole is needed for fixtures, fittings or glazing work. Use with appropriate drill speeds and cooling to preserve tip integrity and achieve clean edges.

Advantages

The steel construction provides strength for steady drilling while the small 3 mm diameter enables precise, minimally invasive holes. The geometry of the tip and shank is optimized for brittle surfaces to reduce cracking and chipping when used with correct technique. Supplied as a single piece, the Dedra DED1530 is convenient for one-off tasks or as a replacement bit in maintenance and installation kits.

Suitable for

• Drilling small holes in glass panes and mirrors
• Creating pilot or fixture holes in ceramic wall and floor tiles
• Precision tasks in glazing, bathroom and kitchen installations

Key specifications

• Diameter: 3 mm
• Material: steel
• Intended materials: glass, ceramic tile
• Quantity: 1 piece

How to use

Secure the workpiece and mark the drilling point. Use a rotary drill or drill press with a steady feed; start at low speed to establish the hole and increase speed moderately as appropriate for the material. Apply light, consistent pressure and avoid forcing the bit. Use water or a suitable coolant intermittently to reduce heat buildup and prolong tool life. If drilling glass, consider supporting the workpiece with padding to prevent vibrations and reduce the risk of cracking.

Usage recommendations

Operate with compatible drills at manufacturer-recommended speeds for glass and tile; use protective eyewear and gloves. For best results, use cooling and pause periodically to clear debris. Replace the bit if the tip shows signs of wear or if drilling quality deteriorates.
