Drill bit for metal Irwin HSS cylindrical 5.2 mm (10502283)

Irwin HSS cylindrical drill bit with a 5.2 mm diameter is designed for drilling clean, accurate holes in a variety of metal materials. Manufactured from high-speed steel (HSS), this solid-drill geometry provides resistance to wear and improved heat tolerance during continuous cutting of ferrous and non-ferrous metals. The cylindrical shank ensures compatibility with standard drill chucks and hand or bench drills used in workshops and maintenance environments.

Advantages

The HSS material delivers a balance of hardness and toughness for consistent drilling performance and longer tool life when compared to general-purpose carbon-steel bits. Its heat resistance reduces deformation and maintains cutting edge integrity at elevated temperatures. The 5.2 mm diameter offers a common, precise hole size for fittings and fasteners, while the cylindrical shank enables quick and secure mounting in standard chucks without special adapters.

Suitable for

• Drilling holes in sheet metal and metal panels
• Creating clearance or pilot holes for bolts, rivets and fasteners
• Workshop maintenance and machinery repair tasks
• Fabrication of metal components and light engineering work

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 5.2 mm
• Shank type: Cylindrical shank for standard chucks
• Intended materials: Ferrous and non-ferrous metals (sheet metal, pipes, components)
• Typical applications: Drilling, clearance and pilot hole production in metal

How to use

Secure the drill bit in a properly sized chuck so the shank is clamped firmly and runout is minimised. Select an appropriate spindle speed and feed rate for the specific metal being drilled — lower speeds for hard ferrous alloys, higher speeds for softer non-ferrous metals. Use cutting lubricant or coolant for improved chip evacuation and reduced heat in the cutting zone when drilling thicker or harder metals. After drilling, retract the bit carefully to clear chips and avoid scoring the hole walls.

Usage recommendations

For best results, start with a pilot hole when working on thicker material, apply steady pressure without forcing the bit, and use recommended cutting fluids for the metal type. Inspect the bit regularly for wear or chipping and replace when the cutting edge becomes dull to maintain hole quality and reduce risk of breakage.
