Metal drill bit DeWalt DT20614-QZ HEX 1/4" 9.0 mm

DeWalt DT20614-QZ HEX 1/4" 9.0 mm is a metal drill bit engineered for drilling in steel and other metals. It features a 9.0 mm cutting diameter and a 1/4" hex shank that fits quick-change chucks and impact drivers accepting hex shanks. The drill bit has a hardened tip and a precision-ground flute profile to promote consistent chip evacuation and improved wear resistance, supporting longer tool life during repetitive metalworking tasks.

Advantages

The hardened tip increases cutting durability and maintains edge integrity when working with various ferrous and non-ferrous metals. The precision-ground flute ensures efficient chip removal and reduces heat buildup during continuous drilling. The 1/4" hex shank provides secure bit retention in quick-change holders and impact drivers, minimizing cam-out and improving torque transfer. Overall construction is optimized for repeatable hole accuracy and extended service life under professional and DIY use.

Suitable for

• Drilling holes in steel, iron and other metal sheets and plates
• Use with quick-change chucks and 1/4" hex impact drivers
• Workshop, construction and maintenance metalworking tasks
• Repair, retrofit and fabrication projects requiring consistent hole quality

Key specifications

• Cutting diameter: 9.0 mm
• Shank type: 1/4" hex
• Material tip: hardened cutting tip
• Flute type: precision-ground flute for chip evacuation
• Application: designed specifically for drilling metal

How to use

Secure the drill bit in a compatible quick-change chuck or 1/4" hex impact driver, ensuring the shank is fully seated. Select an appropriate drilling speed for the metal type and thickness — lower speeds for harder steels and higher speeds for softer metals — and apply steady, moderate feed pressure. Use cutting fluid or lubricant when drilling thicker or harder metals to reduce heat and extend tool life. After drilling, retract the bit periodically to clear chips and prevent clogging of the flute.

Usage recommendations

For best results, pair the bit with stable clamping of the workpiece, appropriate cutting fluid for the metal you are working with, and torque-controlled drivers or drills. Inspect the tip periodically and replace the bit if excessive wear or chipping is observed to maintain hole quality and operator safety.
