Drill bit Irwin HSS straight shank 4.1 mm for metal, model 10502212

Irwin HSS drill bit, 4.1 mm with a straight (cylindrical) shank, designed specifically for drilling metal. Constructed from high-speed steel (HSS) to provide hardness and temperature resistance during cutting operations, this bit delivers consistent performance for creating precise small-diameter holes in both ferrous and non-ferrous metals. The straight shank fits standard chucks in handheld drills and drill presses, making it suitable for workshop, repair and fabrication environments where accuracy and reliable edge retention are required.

Advantages

The HSS material offers good wear resistance and heat tolerance for sustained drilling in metal. The 4.1 mm diameter provides a balance between rigidity and accessibility for tight or detailed work. A straight shank ensures compatibility with a wide range of drill chucks and accessories, and the geometry of the cutting tip is optimized for clean entry and reduced walking on metal surfaces. The bit is compact and intended for controlled, precise drilling tasks.

Suitable for

• Drilling small-diameter holes in steel, aluminum, brass and other metals
• Use in handheld drills for on-site repair and maintenance
• Use in drill presses for workshop fabrication and repetitive drilling
• Pilot holes for screws, rivets or metal fasteners

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Straight (cylindrical) shank
• Drill diameter: 4.1 mm
• Intended application: Metalworking (ferrous and non-ferrous metals)

How to use

Secure the drill bit in the chuck of a handheld drill or drill press, ensuring the straight shank is fully seated and tightened. Mark the drilling point on the workpiece and, if necessary, use a center punch to prevent walking. Start at low speed to establish the hole, then increase speed and apply steady, moderate pressure appropriate for the material being drilled. Use short, controlled pecks when drilling thicker sections to clear chips and reduce heat build-up. After completing the hole, withdraw the bit while the tool is running briefly to clear remaining chips, then stop the machine and remove the bit.

Usage recommendations

For improved tool life and hole quality when drilling metal, use cutting fluid or lubricant, maintain proper drill speeds for the specific metal, and periodically withdraw the bit to clear chips and cool the cutting edge.
