Drill bit Dedra DED1529Q04, 4 mm diameter, 64 mm length, for wood/plastic/aluminium/brick/glass

Single Dedra DED1529Q04 drill bit with a 4 mm diameter and overall length of 64 mm. Designed for drilling small-diameter holes in a variety of materials including wood, plastic, aluminium, brick and glass. Supplied as a single piece, this drill bit is intended for general-purpose tasks, repairs and installations where a compact, precise hole is required.

Advantages

The 4 mm cutting diameter and 64 mm length provide a balance between precision and reach for light- to medium-duty drilling. The geometry is optimised for clean entry and controlled drilling in both soft and harder materials listed, reducing chipping on brittle surfaces. Single-piece supply makes it convenient to carry for occasional use or to keep as a replacement in a professional toolkit.

Suitable for

• Drilling pilot and mounting holes in wood and composite materials
• Creating small holes in plastic and PVC for fittings and cable passages
• Drilling thin aluminium sections and light metalwork
• Making openings in brick for anchors and dowels
• Careful drilling in glass with appropriate technique and accessories

Key specifications

• Cutting diameter: 4 mm
• Overall length: 64 mm
• Suitable materials: wood, plastic, aluminium, brick, glass
• Pack count: 1 piece

How to use

Fit the drill bit into a compatible drill or driver with the correct chuck tightening. Use an appropriate rotational speed for the material: lower speeds for glass and brick, moderate speeds for aluminium and plastic, and medium-to-high speeds for wood. Apply steady, even pressure and avoid excessive force to prevent bit wandering or material damage. For glass and brittle masonry, use a depth stop and consider supporting the workpiece to reduce vibration. Withdraw the bit occasionally to clear chips when drilling deeper holes.

Usage recommendations

Use safety goggles and hearing protection when operating power tools. For drilling glass, use lubricant or water and start with a small pilot mark to reduce the risk of cracking. When drilling masonry, use a hammer or rotary hammer function only if the drill bit and tool rating permit; otherwise use a specialised masonry bit. Inspect the bit for wear or damage before use and replace if the cutting edge is dull.
