Drill Bit Irwin HSS cylindrical 5 mm (model 1863349)

Irwin HSS cylindrical 5 mm is a high-speed steel drill bit designed for creating precision holes in metal. The 5 mm diameter and two-flute geometry provide a balance between cutting speed and hole quality when working with steel, iron and non-ferrous metals. The cylindrical shank is compatible with standard chucks on handheld drills and drill presses, which makes this HSS drill bit suitable for routine workshop, fabrication and maintenance tasks.

Advantages

The high-speed steel construction offers good wear resistance and heat tolerance for drilling at moderate speeds without frequent dulling. The cylindrical shank ensures stable clamping in common three-jaw chucks and keyless chucks, reducing runout and improving concentricity. The 5 mm diameter allows accurate positioning for precision applications while remaining robust enough for general metalworking. The standard two-flute geometry evacuates chips effectively in many through-hole and pilot-hole situations.

Suitable for

• Drilling holes in mild and alloy steels
• Creating pilot and through holes in iron and cast materials
• Working with non-ferrous metals such as aluminium and brass
• Use with handheld drills and bench drill presses
• General workshop fabrication, maintenance and repair

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical (straight shank)
• Diameter: 5 mm
• Flute count: 2
• Intended use: metal drilling (steel, iron, non-ferrous metals)

How to use

Secure the drill bit in a properly sized chuck, ensuring the shank is seated squarely to minimize runout. Select an appropriate spindle speed and apply cutting lubricant when drilling harder steels or when producing deeper holes to reduce heat and improve tool life. Start with a steady feed rate and moderate pressure; withdraw the bit periodically on deeper holes to clear chips and prevent clogging. For small-diameter holes, use a center punch to mark the drilling point and maintain bit alignment throughout the operation.

Usage recommendations

Use cutting fluid for drilling stainless or difficult-to-machine alloys, and choose lower speeds for harder materials. Inspect the tip for wear before each use and replace the drill bit if chipping or significant dulling is present to maintain hole accuracy and safety.
