Drill bit for metal Smart HSS cylindrical 3 mm, set of 10 (MPN 11-030)

Smart HSS cylindrical drill bit, 3 mm diameter, set of 10 pieces designed for drilling metal and metal alloys. These high-speed steel (HSS) bits are intended for creating precise small holes in thin to medium-thickness metal sheets and components. The cylindrical shank ensures compatibility with standard chucks in hand drills and drill presses, while the HSS material provides abrasion resistance and heat tolerance for general metalworking tasks.

Advantages

The set includes ten identical 3 mm HSS bits suited for repetitive drilling tasks and small production runs. HSS construction delivers a balance of hardness and toughness, improving edge retention during through-holes and reducing the risk of premature wear when cutting ferrous and non-ferrous metals. The straight cylindrical shank allows stable clamping in common drill chucks and simplifies bit changes. The 3 mm diameter supports precise drilling for fittings, fasteners, and component assembly operations.

Suitable for

• Drilling holes in thin to medium-thickness steel sheets and metal plates
• Creating pilot or clearance holes for screws, rivets, and bolts
• Small metal fabrication, repair, and maintenance tasks
• Use with hand-held drills and bench drill presses

Key specifications

• Material: high-speed steel (HSS)
• Tip/type: standard twist drill geometry for metal
• Diameter: 3 mm
• Shank: cylindrical (straight) shank for standard chucks
• Quantity: 10 pieces per set

How to use

Select the 3 mm HSS bit and secure it in the drill chuck ensuring proper alignment and tight clamping. Mark the drilling point on the workpiece and, if necessary, use a center punch to prevent wandering. Use cutting fluid or coolant when drilling thicker or harder metals to reduce heat and improve tool life. Apply steady, moderate feed pressure and maintain appropriate spindle speed for the material being drilled; slow down when penetrating harder alloys. After use, clean chips from the flutes and store the bits dry to prevent corrosion.

Usage recommendations

For best results when drilling steel, use a lubricant to extend bit life and reduce heat. Match drilling speed to material thickness: higher speeds for thinner non-ferrous metals, lower speeds for thicker or hardened ferrous materials. Inspect bits for wear and replace when cutting becomes inconsistent or the tip is chipped.
