Drill bit set AWTools AW METAL HSS M2 19 pcs 1.0–10.0 mm

AWTools AW METAL HSS M2 drill bit set contains 19 high-speed steel bits in metric sizes from 1.0 mm to 10.0 mm, designed for drilling metal and general-purpose workshop tasks. The set covers fine to medium hole diameters commonly required in maintenance, fabrication and DIY applications. HSS M2 material provides a balance of hardness and toughness suitable for drilling mild steel, sheet metal and other common ferrous and non-ferrous metals when used with appropriate speeds and coolant.

Advantages

The bits are manufactured from HSS M2 for wear resistance and thermal stability during higher-speed drilling. The set includes a broad progression of metric sizes to allow accurate hole selection without excessive step drilling. Straight shanks ensure compatibility with common chucks and holders, and the ground flutes deliver efficient chip evacuation and stable cutting action. The compact case keeps the bits organised for transport and storage.

Suitable for

• Drilling holes in mild steel, stainless steel (thin sections) and non-ferrous metals
• Workshop maintenance and repair tasks
• Metal fabrication and small-scale sheet metal work
• DIY projects requiring precise metric hole sizes

Key specifications

• Material: High-speed steel (HSS M2)
• Quantity: 19 pieces
• Size range: 1.0 mm to 10.0 mm (metric sizes, step progression)
• Shank type: straight shank for standard chucks
• Finish: ground cutting edges and flutes for chip removal

How to use

Select the appropriate drill diameter for the required hole and secure the workpiece with clamps or a vice to prevent movement. Fit the chosen HSS M2 bit into a suitable drill chuck and set the drill to the recommended speed for the material; use lower speeds for harder metals and larger diameters. Apply cutting fluid or coolant when drilling steel to reduce heat and extend bit life. Use steady, moderate feed pressure and periodically clear chips from the hole to maintain hole quality and prevent bit binding.

Usage recommendations

For best results, start with a pilot or centre punch for accurate hole positioning, and adjust drilling speed according to material hardness: higher rpm for small diameters and softer metals, lower rpm for large diameters and harder metals. Maintain sharp bits, replace worn drills, and use appropriate lubrication to maximise life and maintain clean hole edges.
