Drill bit for metal Smart HSS cylindrical 7.6 mm set of 5 (model 11-076)

Drill bit for metal Smart HSS cylindrical 7.6 mm set of 5 (model 11-076) are straight-shank high-speed steel (HSS) twist drills designed for drilling steel and non-ferrous metals. Supplied as a set of five identical 7.6 mm diameter cutters, these bits are suitable for use in handheld electric drills and drill presses for tasks that require accurate through-holes and mounting points. The cylindrical shank fits standard drill chucks and the HSS material provides hardness and wear resistance appropriate for general metalworking and maintenance jobs.

Advantages

These HSS drill bits offer a balance of cutting speed and toughness for drilling a variety of ferrous and non-ferrous metals. The straight cylindrical shank ensures secure gripping in a chuck without requiring adapters, while the uniform 7.6 mm diameter across the set simplifies tool selection for repetitive drilling tasks. Made from high-speed steel, the bits retain hardness at elevated cutting temperatures typical of metal drilling, which helps maintain drilling accuracy and tool life under normal workshop conditions.

Suitable for

• Drilling through-holes in steel and non-ferrous metal sheets and plates
• Creating mounting holes for fasteners and fittings
• Repair and maintenance tasks on metal components
• Light fabrication and metalworking projects requiring consistent 7.6 mm holes

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical (straight) shank compatible with standard chucks
• Drill type: Twist drill for metal
• Diameter: 7.6 mm
• Set quantity: 5 identical drill bits
• Intended use: Cutting/drilling in steel and non-ferrous metals

How to use

Select an appropriate cutting speed for the 7.6 mm HSS bit and the material being drilled; lower speeds are recommended for harder steels and higher speeds for softer non-ferrous metals. Secure the workpiece firmly and centre-punch the hole location to prevent walking. Fit the cylindrical shank into a properly tightened drill chuck on a handheld drill or drill press. Apply steady feed pressure, keep the drill perpendicular to the work surface for accurate holes, and withdraw periodically to clear chips when drilling deeper holes. Use cutting fluid or lubricant on steel to reduce heat and extend bit life.

Usage recommendations

For best results and longer tool life, use cutting oil when drilling steel, maintain correct spindle speed for the material, and avoid excessive side loads that can cause chipping. Inspect bits for wear or dulling before use and replace when accuracy or cutting performance declines.
