Drill Bit Smart HSS for Metal 9.3 mm — set of 5

Set of five Smart HSS drill bits with a 9.3 mm diameter, designed for drilling holes in metal. Manufactured from high-speed steel (HSS), these bits combine edge retention and heat resistance to perform reliably when cutting through steel and other common metals. The set is intended for workshop and maintenance tasks and fits handheld drills and drill presses for work on thin to medium-thickness metal sheets and profiles.

Advantages

High-speed steel construction ensures good wear resistance and maintains cutting performance at elevated temperatures. The 9.3 mm diameter provides a standardized hole size suitable for many fastening and assembly tasks. Sold as a set of five, the package offers multiple replacements for repetitive work or projects with several identical holes. Compatibility with both handheld drills and drill presses allows for flexible use in different work environments.

Suitable for

• Drilling holes in steel sheets and metal profiles
• Workshop maintenance and repair tasks
• Installation of fasteners and anchors requiring 9.3 mm holes
• Use with handheld electric drills and drill presses

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 9.3 mm
• Quantity in set: 5 pieces
• Intended material: Steel and common metals
• Tool compatibility: Handheld drills and drill presses

How to use

Secure the workpiece firmly and mark the drilling location. Choose an appropriate drill speed for the metal type and thickness—slower speeds for harder or thicker steel—to reduce heat build-up. Fit the 9.3 mm HSS bit into the drill chuck and ensure it is tightened. Use cutting fluid or lubricant where appropriate to extend bit life and improve chip evacuation. Apply steady pressure and allow the bit to cut at its own rate; withdraw occasionally to clear chips and cool the cutting edge. After drilling, deburr the hole as needed.

Usage recommendations

For best results, match drill speed and feed to the metal being drilled, use cutting fluid on harder steels, and replace worn bits to maintain hole quality. Store the bits in a dry place to prevent corrosion.
