## Summary description

Dedra DED1531 drill bit, 4 mm diameter, made of steel and designed for drilling glass and tile. Supplied as a single piece, this specialty bit is intended for precise holes in brittle surfaces where a standard masonry or wood bit is unsuitable. Suitable for manual or drill press use with appropriate speeds and cooling.

## Long description

Dedra DED1531 drill bit, 4 mm diameter, is a steel specialty bit designed for drilling precise holes in brittle materials such as glass and ceramic tile. Supplied as a single piece, this bit has a geometry intended to minimize chipping and cracking when used at appropriate speeds and with suitable cooling or lubrication. It is compatible with handheld drills and drill presses when the correct feed pressure and rotational speed are observed.
Advantages
The Dedra DED1531 offers a compact 4 mm cutting profile that provides accuracy for small-diameter holes in fragile surfaces. Made of steel, the bit combines rigidity with a tip shape optimized for brittle material, reducing the risk of surface damage. Supplied as one piece, it is ready for immediate use and is easy to mount in standard drill chucks. The simple construction supports stable drilling with minimal vibration when used correctly.
Suitable for
Drilling holes in glass panes
Making openings in ceramic or porcelain tiles
Light repair and installation tasks requiring small-diameter holes in brittle materials
Key specifications
Diameter: 4 mm
Material: steel
Intended materials: glass, tile (ceramic, porcelain)
Quantity: 1 piece
How to use
Secure the workpiece to prevent movement and protect surrounding surfaces. Fit the Dedra DED1531 4 mm bit into the drill chuck and tighten securely. Use low to moderate rotational speeds and apply gentle, steady pressure; excessive force or high speeds can cause cracking. For improved results on glass and tile, use a backing support beneath the workpiece and apply cooling or lubrication (for example, water) to reduce heat and clear debris. When the hole is complete, release pressure and allow the bit to clear before removing the drill.
Usage recommendations
Wear appropriate eye protection and gloves. Test drilling on a scrap piece when possible to determine optimal speed and feed for the specific material. Avoid impact drilling modes; use rotary-only settings to reduce the risk of chipping. If drilling multiple holes, periodically withdraw the bit to clear debris and reapply cooling.
