Metal drill bit HSS Titanium, Irwin, 13.0 mm

Irwin Metal drill bit HSS Titanium, 13.0 mm is a high-speed steel drill designed for accurate drilling in metal. The 13.0 mm diameter and titanium coating provide improved wear resistance and reduced friction compared with uncoated HSS bits. This drill bit is suitable for both hand drills and drill presses and is intended for drilling steel as well as other ferrous and non-ferrous metals in workshop and light repair environments.

Advantages

The titanium coating extends the service life of the high-speed steel core by reducing heat build-up and wear during cutting. The HSS substrate maintains sharpness and edge stability for consistent hole quality, while the 13.0 mm diameter offers a common size for through-holes and clearance holes. Reduced friction from the coating supports faster drilling and cleaner chip evacuation when used at appropriate speeds.

Suitable for

• Drilling holes in mild steel and stainless steel (thin to medium thickness)
• Creating clearance or through-holes for bolts and fasteners
• Workshop repair tasks and general metal fabrication
• Use with hand-held drills and bench drill presses

Key specifications

• Material: high-speed steel (HSS) with titanium coating
• Diameter: 13.0 mm
• Intended materials: ferrous and non-ferrous metals
• Mount type: straight shank suitable for standard drill chucks
• Typical applications: metal drilling, clearance holes, workshop repairs

How to use

Secure the workpiece and select an appropriate drilling speed for the metal type and thickness—lower speeds for harder materials and larger diameters. Use a properly tightened chuck and ensure the drill bit is perpendicular to the surface for accurate holes. Apply steady, moderate feed pressure and allow the bit to clear chips periodically. Use cutting fluid or lubricant to reduce heat and prolong bit life when drilling steel or stainless steel.

Usage recommendations

For best results, start with a small pilot hole when drilling thicker material, maintain correct rotational speed, and use cutting fluid to minimize wear. Regularly inspect the cutting edges for wear and replace the bit when edges dull or drilling quality declines.
