Metal drill bit DeWalt DT20618-QZ HEX 1/4" shank 12.0 mm

DeWalt DT20618-QZ is a metal drill bit with a HEX 1/4" shank and a 12.0 mm cutting diameter designed specifically for drilling into a variety of metal materials. The bit combines a straight flute geometry and a robust body to maintain cutting performance under continuous use. The HEX 1/4" shank provides a secure fit in quick-change chucks, impact drivers and cordless drills, enabling faster bit changes and reduced slippage during use.

Advantages

The HEX 1/4" shank improves retention in holders and minimizes cam-out when used with impact and quick-change systems. The 12.0 mm diameter offers a balance between hole size and tool load for general metalworking tasks. The bit is manufactured to tight dimensional tolerances to provide repeatable hole size and consistent drilling behavior. Materials and heat treatment contribute to wear resistance and extended service life under workshop and on-site conditions.

Suitable for

• Drilling holes in steel and other ferrous metals
• Use with impact drivers, cordless drills and quick-change chucks
• Workshop and professional repair or installation tasks
• Applications requiring repeatable hole diameter and fast bit swaps

Key specifications

• Shank type: HEX 1/4" for secure quick-change fit
• Cutting diameter: 12.0 mm
• Intended material: metal
• Suitable tool types: impact driver, cordless drill, quick-change chuck
• Design focus: repeatable hole size and reduced slippage

How to use

Select a drill or driver with a compatible 1/4" HEX holder and secure the bit firmly in the chuck. Mark the drilling point and, if necessary, center-punch the metal to prevent wandering. Start drilling at a moderate speed with steady pressure; use cutting fluid or lubricant on harder steels to reduce heat and prolong bit life. Withdraw periodically to clear chips and allow cooling for consistent performance.

Usage recommendations

Use appropriate personal protective equipment, clamp workpieces securely, and select drill speeds and lubrication based on the metal type to maximize bit life and hole quality.
