Drill bit DeWalt DT20615-QZ HEX 1/4" shank 9.5 mm metal

Straight shank metal drill bit DeWalt DT20615-QZ with a 1/4" HEX shank and a 9.5 mm cutting diameter is designed for creating precise holes in metal. The bit fits into hex chucks and impact drivers that accept a 1/4" hex shank, providing a secure connection and improved torque transfer during drilling. Intended for workshop, construction and maintenance tasks, this drill bit offers consistent hole size and stable performance on a range of ferrous and non-ferrous metals.

Advantages

The straight 1/4" HEX shank ensures quick and secure tool changes and compatibility with hex adapters and impact drivers. A 9.5 mm cutting diameter gives a standard, easy-to-match hole size for fittings and fasteners. The bit geometry is optimized for metal drilling to reduce walking and allow steady penetration. Constructed to provide repeatable hole quality, it supports efficient workflow in professional and DIY environments.

Suitable for

• Drilling holes in steel, aluminum and other metals
• Workshop and fabrication tasks requiring a 9.5 mm hole
• Construction and maintenance where impact drivers or hex chucks are used
• Rapid tool changes with hex-shank-compatible systems

Key specifications

• Shank type: 1/4" HEX straight shank
• Cutting diameter: 9.5 mm
• Intended material: metal (ferrous and non-ferrous)
• Designed for use with: hex chuck adapters and impact drivers accepting 1/4" hex shank
• Application: through-holes and clearance holes in metal

How to use

Select appropriate drilling speed and apply steady feed pressure to avoid overheating the bit when drilling metal. Secure the workpiece and align the drill bit at the desired location; if needed use a center punch to prevent walking. Insert the 1/4" HEX shank into a compatible chuck or adapter until locked, then start drilling with controlled speed and intermittent backing out to remove chips. Use cutting fluid or coolant for improved tool life and cleaner holes when working with tougher metals.

Usage recommendations

For best results, use appropriate cutting lubricant and moderate drilling speeds based on the metal type. Replace the bit when wear affects hole quality, and store in a dry place to prevent corrosion.
