Metal drill bit DeWalt DT20611-QZ HEX 1/4" 7.5 mm

DeWalt DT20611-QZ HEX 1/4" 7.5 mm is a metal drill bit designed for efficient drilling in steel and other metal materials. The 7.5 mm cutting diameter provides a compact, mid-range size for through-holes and pilot holes in metalworking. The 1/4" HEX shank enables fast, secure insertion into quick-change chucks and impact driver adapters, reducing slippage and improving torque transfer during drilling operations.

Advantages

The hardened steel construction and precise cutting geometry deliver consistent hole quality and extended tool life under normal metal drilling conditions. The HEX shank design ensures reliable grip in compatible chucks and holders, minimizing cam-out and enabling quick bit swaps. The bit’s compact length and 7.5 mm diameter make it versatile for a range of metal fabrication and maintenance tasks while remaining easy to handle in confined spaces.

Suitable for

• Drilling holes in mild steel, sheet metal and thin metal plates
• Creating pilot holes for tapping or fastening in metal components
• Maintenance and repair tasks requiring compact metal drill bits
• Use with impact drivers, drills and quick-change chucks that accept 1/4" HEX shanks

Key specifications

• Cutting diameter: 7.5 mm
• Shank type: 1/4" HEX
• Material: hardened steel suitable for metal drilling
• Intended use: drilling metal (sheets, plates, mild steel)
• Compatibility: quick-change chucks and drivers accepting 1/4" HEX shanks

How to use

Secure the drill bit in a compatible 1/4" HEX chuck or quick-change holder until it locks firmly. Mark the drilling position on the metal surface and, if necessary, use a center punch to prevent walking. Start drilling at low speed to establish the hole, then increase speed and apply steady pressure appropriate for the metal thickness. Use cutting fluid or lubricant when drilling harder steels to reduce heat and prolong bit life. Withdraw the bit periodically to clear swarf and avoid clogging.

Usage recommendations

For best results, match drill speed and feed to the metal type; use lower speeds for harder alloys and apply cutting fluid on thicker or harder materials. Inspect the bit before use and replace it if worn or chipped to maintain hole accuracy and prevent damage to the workpiece or tool.
