Metal drill bit DeWalt DT20616-QZ HEX 1/4" shank 10.0 mm

DeWalt DT20616-QZ is a 10.0 mm metal drill bit with a 1/4" HEX shank designed specifically for drilling into metal. The bit offers a straight drilling profile optimized for clean penetration of steel and other ferrous materials. Its 1/4" hexagonal shank is compatible with quick-change chucks and impact drivers that accept a 1/4" HEX interface, providing fast bit changes and secure retention during high-torque operations in workshop, construction and maintenance settings.

Advantages

The drill bit combines a 10.0 mm cutting diameter with a 1/4" HEX shank for broad compatibility with common power tools. Its straight flute and tip geometry are designed to maintain a steady drilling axis and reduce walking on metal surfaces. The hex shank ensures reliable grip in quick-change holders and impact-ready chucks, allowing efficient transfer of torque and minimizing slippage under load. The bit's design supports repeated bit swaps without additional adapter accessories.

Suitable for

• Drilling holes in mild and medium-hard metals such as steel and iron
• Use with quick-change chucks on cordless drivers and impact drivers
• Workshop metal fabrication and maintenance tasks
• Construction site fastening and through-hole preparation in metal components

Key specifications

• Cutting diameter: 10.0 mm
• Shank type: 1/4" HEX
• Intended material: metal (steel and similar ferrous materials)
• Drill profile: straight/standard twist for metalworking
• Compatibility: quick-change chucks and impact drivers with 1/4" HEX interface

How to use

Secure the 1/4" HEX shank in the quick-change chuck or impact driver following the tool manufacturer's instructions. Mark the drilling position on the metal surface and, if necessary, create a small center punch indent to reduce walking. Start drilling at low speed to establish the hole, then increase speed and apply steady pressure appropriate to the material thickness. Use cutting lubricant when drilling harder metals to extend bit life and improve chip evacuation. Withdraw the bit periodically to clear chips and avoid overheating.

Usage recommendations

For best results, use the drill bit with tools capable of delivering controlled torque and variable speed. Apply cutting fluid when working with harder steels, maintain firm, consistent pressure without forcing the bit, and replace the bit if signs of dulling or chipping appear to preserve hole quality and tool safety.
