Drill bit Irwin HSS cylindrical 2 mm for metal, model 10502482

Irwin HSS cylindrical 2 mm drill bit for metal is a high-speed steel cutting tool designed for precise drilling of small-diameter holes in ferrous and non-ferrous metals. The 2 mm diameter and cylindrical shank make it suitable for use with standard chucks and bench or portable drills. Constructed from HSS material, the bit offers improved wear resistance and heat tolerance for typical metalworking tasks in workshops and on construction sites.

Advantages

The HSS composition delivers a balance of hardness and toughness that resists softening at elevated cutting temperatures, extending tool life during continuous metal drilling. The small 2 mm diameter enables high-precision hole placement and minimal material displacement. The cylindrical shank ensures straightforward clamping in common drill chucks, while the sharp point geometry reduces walking and improves centering on metal surfaces.

Suitable for

• Drilling small-diameter holes in steel and iron
• Precision drilling in non-ferrous metals such as aluminium and brass
• Workshop and general maintenance drilling tasks
• Light construction and fitting work requiring small holes

Key specifications

• Material: High-speed steel (HSS)
• Tip/geometry: Standard twist drill point suitable for metal
• Shank type: Cylindrical shank for standard chucks
• Diameter: 2 mm
• Intended use: Metal drilling (ferrous and non-ferrous)

How to use

Select an appropriate drill speed and feed for a 2 mm HSS bit when working with the chosen metal: lower speeds for harder steels, higher speeds for softer non-ferrous metals. Secure the workpiece and clamp the drill bit in a compatible chuck, ensuring concentric alignment. Use cutting fluid or lubricant for improved chip evacuation and reduced heat when drilling steel or other hard metals. Withdraw periodically to clear chips and avoid clogging the flutes.

Usage recommendations

For best results, use a center punch to mark the drilling point on the metal to prevent walking. Match drill speed to material hardness (e.g., 800–1500 RPM for small HSS bits in soft metals, lower for hardened steels), keep steady pressure, and apply cutting fluid when drilling harder metals to extend tool life and maintain hole quality.
