- Cobalt-alloyed HSS (HSS-Co) โ improved red hardness and wear resistance for
drilling stainless steel, high-tensile and abrasive alloys.
- Fully ground construction โ precision ground flutes and diameter for
accurate, true-running holes and smooth chip evacuation.
- 135ยฐ split-point tip โ self-centring for reduced walking, faster penetration
and less need for centre punching on many jobs.
- Long service life โ withstands higher temperatures and heavy-duty use
better than standard HSS drills when used correctly with cutting fluid.
- Multi-material capability โ suitable for stainless (INOX), hardened/abrasive steels,
cast steel, non-ferrous metals and general steelwork.

£1.71£2.05 – £5.74£6.89Price range: £1.71£2.05 through £5.74£6.89 Excl. VATIncl. VAT
- Cobalt-alloyed HSS (HSS-Co) โ provides excellent heat resistance and hardness
for drilling stainless (INOX), high-tensile and abrasive steels where standard HSS fails quickly.
- 135ยฐ split-point tip* โ self-centring design reduces walking and enables
faster, more accurate starts with less need for centre punching.
- Longer life in tough materials โ 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 โ high manufacturing standards and precision grinding deliver
accurate, round holes with smooth chip evacuation.
- Multi-material performance โ 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 135ยฐ split-point or similar fast-start design โ see packaging for exact details.

- High speed steel (HSS) core โ tough, wear-resistant steel for clean, accurate holes in a wide range of materials.
- Titanium nitride (TiN) coating โ reduces friction and heat build-up for faster cutting and longer bit life compared with uncoated HSS.
- 135ยฐ split point* โ fast starting with reduced walking and less need for centre punching on many applications.
- Suitable for metal, wood & plastics โ ideal for mild steel, non-ferrous metals, alloy sheet, timber, MDF, and many plastics.
- Irwin trade quality โ engineered to meet the demands of professional users for reliability and durability.
*Point style varies by exact Irwin series โ many titanium-coated ranges feature a 135ยฐ split or similar fast-start point. Check pack for specifics.
