Drill bit Irwin 10502492 HSS Pro Series Long 7 mm, high-speed steel, straight shank

Irwin 10502492 HSS Pro Series Long 7 mm is a high-speed steel drill bit designed for drilling metal, wood and plastics. The long flute construction increases cutting reach and improves chip evacuation for deeper holes. The straight shank fits standard drill chucks and the HSS material provides heat resistance and edge retention for repeated use in professional and DIY tasks that require accuracy.

Advantages

The long flute length enables deeper penetration without sacrificing rigidity, while optimized flute geometry helps clear chips efficiently to reduce clogging. High-speed steel construction ensures durability and heat tolerance during continuous drilling. The straight shank offers compatibility with most handheld and bench drills, and the 7 mm diameter provides a balance between material removal rate and hole precision.

Suitable for

• Drilling steel and non-ferrous metals
• Creating holes in wood and laminated boards
• Working with plastics and composite materials
• Deep-hole drilling where extended reach is required
• General workshop and on-site maintenance tasks

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 7 mm
• Shank type: straight shank for standard chucks
• Flute: long flute design for deeper cutting reach
• Recommended use: drilling in metal, wood and plastics

How to use

Secure the drill bit in a compatible drill chuck and tighten firmly. Select an appropriate rotational speed for the material: lower speeds for hard metals, moderate speeds for wood and higher speeds for softer plastics. Apply steady axial pressure and allow the bit to cut without forcing; retract periodically on deep holes to clear chips and avoid overheating. Use cutting fluid or lubricant when drilling metals to extend tool life and improve chip evacuation.

Usage recommendations

For optimal results when drilling metals, use cutting oil and moderate speed; when working with wood or plastics, run the drill at higher speed and ensure secure clamping of the workpiece. Inspect the bit for wear before use and replace if the cutting edges are rounded or damaged.
