Drill bit Irwin HSS cylindrical 6 mm, model 10502490

Irwin HSS cylindrical 6 mm drill bit is a high-speed steel solid drill designed for drilling metal and other hard materials. The 6 mm diameter and cylindrical shank make it compatible with standard three-jaw chucks and bench-mounted drill presses. This drill bit is intended for tasks requiring accurate, clean holes in steel, cast iron and non-ferrous metals; it is suitable for workshop and industrial environments as well as maintenance and repair work.

Advantages

The high-speed steel construction provides good hardness and heat resistance for sustained drilling in metal without rapid wear. The solid one-piece design ensures concentricity and rigidity for precise 6 mm holes. The cylindrical shank allows quick mounting in conventional chucks and improves versatility across hand drills and drill presses. The cutting geometry is optimized for metalworking to reduce walking and improve hole finish.

Suitable for

• Drilling through mild and hardened steel
• Creating precise 6 mm holes in cast iron and non‑ferrous metals
• Workshop, maintenance and industrial repair tasks
• Use with hand drills and bench drill presses equipped with standard chucks

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 6 mm
• Shank type: cylindrical (round) for standard chucks
• Design: solid, one-piece construction
• Typical applications: metal drilling, maintenance and repair

How to use

Select the appropriate speed for the workpiece material and secure the workpiece firmly in a vise or with clamps. Fit the 6 mm cylindrical shank into a suitable chuck and tighten securely. Use cutting oil or lubricant when drilling steel and other metals to reduce heat and prolong tool life. Start at low speed to establish a center and then increase speed as appropriate, applying steady, moderate feed pressure until the hole is complete. Clear chips regularly to avoid clogging and overheating.

Usage recommendations

For best results when drilling steel, use a suitable cutting fluid and moderate speeds; replace the bit once signs of wear or chipping appear to maintain hole quality and safety.
