Metal drill bit DeWalt DT20610-QZ 1/4" HEX shank, 7.0 mm cutting diameter

DeWalt DT20610-QZ metal drill bit is engineered for efficient drilling in metal with a 7.0 mm cutting diameter and a 1/4" hex shank compatible with quick-change chucks and impact drivers. The bit is designed to deliver consistent hole quality in a range of ferrous and non-ferrous metals while allowing fast bit changes and secure retention in hex-tool holders. Its geometry and shank form support steady torque transfer and reduce wobble during operation.

Advantages

The 1/4" hex shank enables rapid swapping in quick-change systems and improves grip under high-torque conditions. A 7.0 mm cutting diameter provides a common hole size for bolts, rivets and assemblies, and the bit's construction supports durability under workshop and on-site use. Compatibility with impact drivers expands application flexibility, and the bit's streamlined design aids accurate centring and straight drilling.

Suitable for

• Drilling through mild steel, stainless steel, aluminium and other metal sheets
• Installing bolts, rivets and threaded inserts requiring a 7.0 mm hole
• Use with quick-change chucks and 1/4" hex impact drivers for fast bit changes
• General metal fabrication, maintenance and on-site repair tasks

Key specifications

• Cutting diameter: 7.0 mm
• Shank type: 1/4" hex shank for quick-change systems
• Intended material: metal (ferrous and non-ferrous)
• Typical use: drilling holes for fasteners and assemblies
• Drive compatibility: standard 1/4" hex sockets and quick-change chucks

How to use

Secure the DeWalt 7.0 mm metal drill bit in a compatible quick-change chuck or 1/4" hex impact driver. Select an appropriate drilling speed for the material—lower speeds for harder metals and higher speeds for softer metals—and apply steady, moderate pressure. Use cutting fluid or lubricants when drilling harder steels to reduce heat and extend tool life. Back the bit out occasionally to remove chips and prevent clogging.

Usage recommendations

Wear appropriate personal protective equipment including eye and hearing protection. Match drill speed, feed pressure and lubrication to the metal type. For precise holes, pilot drill smaller diameters first when required and clamp the workpiece securely to avoid movement.
