Drill bit for metal Irwin HSS cylindrical 1 mm, set of 2

Irwin HSS cylindrical drill bits, diameter 1 mm, pack of 2 are precision tools designed for small-diameter metal drilling. Manufactured from high-speed steel (HSS), these bits are intended for creating clean, accurate holes in a variety of metals and metal alloys. The cylindrical shank fits standard drill chucks and makes them suitable for bench drills, hand drills and micro-drilling setups used in metalworking, electronics, jewelry repair and model making.

Advantages

High-speed steel construction provides a balance of hardness and toughness, enabling reliable cutting and improved wear resistance when drilling thin or small holes. The 1 mm diameter offers precision for fine tasks, while the set of two ensures a backup or pair for repetitive work. The cylindrical shank ensures compatibility with common drill chucks and simplifies replacement and setup.

Suitable for

• Drilling small-diameter holes in sheet metal and thin metal parts
• Precision work in electronics and circuit board enclosures
• Jewelry repair and detailed metal craft
• Model making and scale fabrication requiring fine holes

Key specifications

• Material: High-Speed Steel (HSS)
• Diameter: 1 mm
• Shank type: Cylindrical
• Pack contents: 2 drill bits
• Intended materials: Various metals and metal alloys

How to use

Secure the appropriate drill bit in a compatible drill chuck, ensuring the bit is centered and tightly clamped. Mark the drilling position on the workpiece and, if necessary, use a center punch to prevent walking. Start at low speed to establish the hole, then apply steady pressure and increase speed as appropriate for the metal being drilled. Use cutting lubricant for harder metals or prolonged drilling to reduce heat and extend bit life. After use, remove metal debris and store the bits in a dry place.

Usage recommendations

For best results when drilling metals, use a suitable cutting fluid, maintain moderate feed pressure, and avoid overheating by using intermittent drilling or backing off periodically. Replace or re-sharpen bits if performance declines to maintain hole quality and reduce risk of breakage.
