Metal drill bit set DeWalt DT20620-QZ 10 pcs HEX 1/4

DeWalt metal drill bit set DT20620-QZ 10 pcs HEX 1/4 is a compact collection of ten metal-cutting drill bits with a 1/4-inch hex shank designed for use in drills and impact drivers that accept hex bits. The set is built for drilling through various metals and integrates a quick-change HEX connection that allows fast replacement of bits and compatibility with standard magnetic bit holders. The bits are organized to provide a straightforward selection for common metalworking sizes and straightforward on-site maintenance tasks.

Advantages

The DeWalt metal drill bit set offers robust construction for metal drilling tasks, a 1/4" HEX shank for secure fit in compatible chucks and bit holders, and a quick-change interface to speed up bit swaps. Its ten-piece assortment covers frequently used diameters for repair, fabrication and maintenance work, reducing downtime and the need to search for individual bits. The design is intended for reliable engagement with impact drivers as well as conventional drills that accept hex shanks.

Suitable for

• Drilling holes in steel, aluminium and other non-ferrous metals
• On-site repair and maintenance tasks
• Fabrication, assembly and machine-shop preparatory work
• Use with drills, impact drivers and magnetic bit holders that accept 1/4" hex shanks

Key specifications

• Number of pieces: 10
• Shank type: 1/4" hex
• Intended material: metal (steel, aluminium, other metals)
• Connection: quick-change HEX compatibility
• Compatibility: suitable for drills and impact drivers accepting 1/4" hex bits and magnetic bit holders

How to use

Select the appropriate drill bit size from the set for the metal and hole diameter required. Insert the 1/4" hex shank into the drill or impact driver chuck or magnetic bit holder until securely seated. Use appropriate cutting speed and moderate pressure for the metal type; apply cutting fluid or lubricant when drilling harder steels to extend bit life and improve chip evacuation. After use, wipe the bits clean and store them in their original case or designated holder to prevent damage and corrosion.

Recommendations

Wear eye and hand protection when drilling metal. For best results, start with a small pilot hole for large diameters, maintain steady feed rate, and use lubrication on harder alloys. Inspect bits regularly for wear and replace any that show dulling, chipping, or deformation.
