Drill Bit Set DeWalt HSS for Metal, Cylindrical Shank, Sizes 1.5–9.5 mm (DT5913-QZ)

DeWalt HSS drill bit set with cylindrical shanks, covering fractional sizes from 1.5 mm to 9.5 mm, is designed for drilling a wide range of metals. The set groups common small-to-medium diameters useful for general metalworking tasks, maintenance, repair and workshop use. These high-speed steel (HSS) bits are suitable for handheld drills and drill presses where cutting speed, edge retention and wear resistance are needed for drilling into steel, iron and non-ferrous metals.

Advantages

The HSS material provides good hardness and heat resistance during metal drilling, helping to maintain sharp cutting edges and reduce premature wear. Cylindrical shanks ensure compatibility with standard drill chucks and allow easy bit changes. The included range of sizes from 1.5 mm to 9.5 mm covers common fractional diameters used in fabrication and repair, reducing the need to switch between multiple individual bits. The set’s construction supports consistent hole quality across repeated use in workshop and maintenance environments.

Suitable for

• Drilling holes in mild and alloy steels
• Maintenance and repair tasks in workshops and garages
• General metal fabrication and assembly work
• Use with handheld drills and drill presses

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical
• Diameter range: 1.5 mm–9.5 mm (fractional sizes included)
• Intended use: Drilling metal (steel, iron, non-ferrous metals)
• Compatibility: Standard drill chucks on handheld drills and drill presses

How to use

Secure the chosen drill bit in the drill chuck making sure it is properly centered and tightened. Select an appropriate cutting speed for the material being drilled—slower speeds for harder steels and higher speeds for softer metals. Apply steady, moderate pressure and use cutting fluid or lubricant when drilling steels to reduce heat buildup and extend bit life. After drilling, clear swarf and inspect the bit for wear before reuse.

Usage recommendations

For best results and longer tool life, use cutting lubricant when drilling steel, start with a pilot hole for larger diameters, and avoid excessive feed rates that can overheat the bit. Replace or resharpen bits showing significant wear or chipping to maintain hole quality and safety.
