Drill Bit Dedra DED1529Q14 1.4 cm Diameter 90 mm Length

The Dedra DED1529Q14 drill bit has a 1.4 cm diameter and a 90 mm overall length, designed for creating clean, consistent holes in a range of common materials. Intended as a single-piece tool, this drill bit works with standard drill chucks and is described as compatible with wood, plastic, aluminium, brick and glass. Its dimensions offer a balance between reach and rigidity for both through-holes and shallow drilling tasks.

Advantages

The Dedra DED1529Q14 combines a relatively large 1.4 cm cutting diameter with a moderate 90 mm length to provide stable drilling performance. Compatibility with multiple materials reduces the need to change bits frequently, and the single-piece supply simplifies inventory for small projects. The design emphasises straightforward use in common handheld and bench drills.

How to use

Select a drill or driver with a compatible chuck capacity and set the correct rotational speed for the material you are working with. Secure the workpiece to prevent movement. For wood and plastic, moderate to high speed and light feed pressure are appropriate; for aluminium use moderate speed and steady pressure; for brick use a lower speed with firm, controlled feed. When drilling glass use a specialised technique: apply light pressure, use lubricant or water as a coolant, and start with a shallow pilot to avoid cracking. Withdraw the bit occasionally to clear chips or dust.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Match drill speed and feed to the material, and avoid excessive side force to preserve bit life. When drilling masonry or glass, consider using appropriate backing and cooling methods to reduce the risk of breakage. Store the bit dry and protected to prevent damage.
