    £1.71 £5.74Price range: £2.05£1.71 through £6.89£5.74 Incl. VATExcl. VAT

    • Cobalt-alloyed HSS (HSS-Co) – provides excellent heat resistance and hardness
      for drilling stainless (INOX), high-tensile and abrasive steels where standard HSS fails quickly.
    • 135° split-point tip* – self-centring design reduces walking and enables
      faster, more accurate starts with less need for centre punching.
    • Longer life in tough materials – withstands higher temperatures and heavy-duty use,
      significantly extending life compared with conventional HSS drill bits (when used correctly with cutting fluid).
    • True, precise holes – high manufacturing standards and precision grinding deliver
      accurate, round holes with smooth chip evacuation.
    • Multi-material performance – suitable for stainless steel, alloy and carbon steels, cast steel,
      non-ferrous metals and general steelwork      , plus many workshop tasks.

    *Point geometry may vary slightly by Irwin series; most Irwin cobalt ranges feature a 135° split-point or similar fast-start design – see packaging for exact details.

    • High speed steel (HSS) core – tough, wear-resistant steel for clean, accurate holes in a wide range of materials.
    • Titanium nitride (TiN) coating – reduces friction and heat build-up for faster cutting and longer bit life compared with uncoated HSS.
    • 135° split point* – fast starting with reduced walking and less need for centre punching on many applications.
    • Suitable for metal, wood & plastics – ideal for mild steel, non-ferrous metals, alloy sheet, timber, MDF, and many plastics.
