Metal Drill Bit Irwin IR HSS PRO TIN DIN 338 6.0 mm, 6.0-CYL

Irwin IR HSS PRO TIN DIN 338 6.0 mm, 6.0-CYL is a high-speed steel (HSS) metal drill bit with a titanium nitride (TiN) coating and a 6.0 mm cutting diameter. Manufactured to the DIN 338 standard with a cylindrical shank, this drill bit is designed for insertion into standard drill chucks and is intended for drilling into steel and a range of other metals. The TiN coating enhances surface hardness and reduces friction, contributing to extended tool life and more consistent cutting performance in metalworking applications.

Advantages

The TiN coating improves wear resistance and reduces heat buildup during drilling, resulting in longer service life compared with uncoated HSS bits. Conformance to DIN 338 ensures consistent geometry and reliable cutting behaviour, while the cylindrical shank provides compatibility with a wide variety of hand drills and bench drills. The 6.0 mm diameter offers a balance between rigidity and cutting speed, suitable for through-holes and pilot holes in metal components.

Suitable for

• Drilling steel and stainless steel (with appropriate speeds and coolant)
• Creating holes in non-ferrous metals such as aluminium and brass
• Workshop and maintenance tasks requiring repeatable, precise metal drilling
• On-site metal fabrication, repair, and installation work

Key specifications

• Material: High-speed steel (HSS)
• Coating: Titanium nitride (TiN)
• Cutting diameter: 6.0 mm
• Shank type: Cylindrical shank
• Standard: DIN 338 geometry
• Application: Metal drilling (ferrous and non-ferrous)

How to use

Select an appropriate drill speed and feed for the workpiece material and secure the workpiece to prevent movement. Install the 6.0 mm cylindrical shank into a compatible chuck and tighten securely. For steel and stainless steel, use cutting fluid or coolant to reduce heat and prolong tool life; for aluminium and softer metals, reduce cutting speed to avoid material binding. Apply steady pressure while keeping the drill perpendicular to the surface until the hole is complete, then withdraw the bit while running at low speed to clear chips.

Usage recommendations

Use moderate cutting speeds for stainless steel and higher speeds for mild steel and non-ferrous metals, always employing coolant when drilling hard or thick sections. Re-sharpening is possible but will alter the TiN coating; replace the bit when wear affects hole quality or concentricity.
