## Summary description

Irwin HSS cylindrical drill bit, 4 mm diameter, designed for drilling metal. Made from high-speed steel (HSS) for durability and heat resistance during cutting. Cylindrical shank suitable for standard chucks and drill presses. Intended for accurate through-holes and metalworking tasks in steel, iron and non-ferrous metals.

## Long description

Irwin HSS cylindrical drill bit 4 mm is engineered for precise drilling in metal. Constructed from high-speed steel (HSS), this 4 mm diameter bit offers heat resistance and wear performance suited to conventional metalworking. The cylindrical shank is compatible with standard chucks and drill presses, enabling straightforward installation and reliable concentricity for through-holes in steel, iron and non-ferrous metals.
Advantages
The high-speed steel material provides a balance of hardness and toughness that reduces edge wear and maintains cutting performance at elevated temperatures. The 4 mm diameter ensures controlled chip formation and accurate hole sizes, while the cylindrical shank simplifies clamping in bench drills and portable drills with standard chucks. The bit’s geometry is optimized for metal cutting to achieve cleaner hole walls and consistent penetration.
Suitable for
 Drilling through mild and medium-hard steels
 Creating holes in iron and cast iron components
 Working with non-ferrous metals such as aluminium and copper
 General metal fabrication and maintenance tasks
 Workshop use with drill presses and hand drills
Key specifications
 Material: high-speed steel (HSS)
 Diameter: 4 mm
 Shank type: cylindrical (straight) shank for standard chucks
 Intended application: metal drilling, through-holes
 Suitable materials: steel, iron, non-ferrous metals
How to use
Select a compatible drill chuck and securely clamp the cylindrical shank to minimize runout. Mark the drilling position and use a center punch for accurate starts on flat metal surfaces. Start at a low speed to establish the hole, then increase speed according to the material and drill press or handheld drill capability. Apply steady feed pressure and use cutting fluid or coolant for improved tool life and chip evacuation when drilling tougher steels. Retract periodically on deep holes to clear chips and avoid overheating.
Usage recommendations
For best results, match drilling speed and feed to the workpiece: lower speeds for harder steels, higher speeds for softer non-ferrous metals. Use cutting fluid when drilling steels to extend life of the HSS bit and improve surface finish. Inspect the bit for wear or chipping before use and replace when cutting performance degrades.
