Drill bit HSS Pro 13 mm, Irwin 10502361

Solid HSS Pro twist drill bit with a 13 mm diameter from Irwin, designed for metalworking and general-purpose drilling. Made of high-speed steel (HSS), the bit combines heat resistance and edge retention to maintain cutting performance when drilling steel, iron and similar metals. The straight flute, split point geometry and robust shank make it suitable for use in both hand-held drills and drill presses when correct speeds and cutting fluids are applied.

Advantages

The HSS Pro 13 mm drill bit offers precise hole-making with good wear resistance and reliable cutting life typical of high-speed steel tooling. Its ground geometry reduces walking on the workpiece and improves centring, while the solid construction delivers stable performance under moderate drilling loads. The bit can be resharpened to extend service life and is compatible with standard 13 mm chucks.

Suitable for

• Drilling holes in mild and medium carbon steel
• General metal fabrication and repair work
• Use in hand drills and bench drill presses
• Pilot holes and through-holes in thin to moderate material thicknesses

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 13 mm
• Tip style: split point / reduced walking
• Shank type: cylindrical, suitable for standard chucks
• Flute: 2-flute twist design for chip evacuation

How to use

Select an appropriate drilling speed for the material being worked—lower speeds for harder steels and higher speeds for softer metals. Secure the workpiece to prevent movement, mark the drilling location and, if required, start with a centre punch to improve centring. Use cutting fluid or oil when drilling metals to reduce heat and prolong the bit life. Apply steady, moderate feed pressure; if the bit overheats, pause to allow cooling or back out to clear chips.

Usage recommendations

For best results when drilling steel and iron, use suitable cutting lubricant, maintain correct spindle speed and avoid excessive axial force. Resharpen the bit when edge wear affects performance and replace when the geometry cannot be restored safely.
