Drill Bit for Metal Smart HSS Cylindrical 2 mm, 10 pcs (11-020)

Drill Bit for Metal Smart HSS Cylindrical 2 mm, 10 pcs is a set of high-speed steel (HSS) cylindrical shank drill bits designed for precise drilling in steel and non-ferrous metals. Each 2 mm bit in the 10-piece set is intended for small-diameter holes where accuracy and consistent results are required. The cylindrical shank is compatible with standard chucks on hand drills and drill presses, making the set suitable for workshop and repair tasks that demand controlled, repeatable hole making in thin plates, sheet metal, and small components.

Advantages

The HSS construction offers good wear resistance and heat tolerance for metal drilling at typical workshop speeds. The uniform 2 mm diameter across the set ensures consistent hole sizes for repeated operations. Cylindrical shanks provide reliable clamping in keyed and keyless chucks. Supplied as a set of 10, the bits allow for multiple replacement options during extended projects or for keeping spare tools on hand.

Suitable for

• Drilling small, precise holes in mild and alloy steels
• Working with non-ferrous metals such as aluminum, brass, and copper
• Use in hand drills and drill presses for maintenance and fabrication
• Model making, electronics enclosures, and DIY metal repair tasks

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical
• Diameter: 2 mm
• Quantity: 10 pieces per set
• Intended use: Metal drilling (steel and non-ferrous metals)

How to use

Secure the chosen 2 mm HSS bit in the drill chuck, ensuring the shank is fully seated and tightened to prevent slipping. Mark the hole position on the workpiece and, if needed, create a small center punch indentation to guide the bit. Apply consistent feed pressure and use appropriate drilling speed for the material—moderate speed for steel and higher speeds for softer non-ferrous metals. Use cutting lubricant when drilling steel to reduce heat and extend bit life. Clear chips regularly and avoid excessive side loads that can break small-diameter bits.

Usage recommendations

For best results, select drill speeds appropriate to the material and use a suitable cutting fluid when working with steel. Store the set in a dry place and replace bits at the first sign of excessive wear or chipping to maintain hole accuracy and reduce the risk of breakage.
