The IRW10502535 is an 8.5mm HSS Cobalt Drill Bit supplied in a pack of 5, offering a larger intermediate diameter for specialist applications in stainless steel and high alloy steels. This size is particularly useful for clearance holes for larger fixings, pilot drilling for tapping operations, and applications where precise sizing between standard diameters is essential. The 8.5mm diameter is commonly used in heavy engineering and fabrication environments. With 5% cobalt integrated throughout, these drill bits deliver outstanding heat and abrasion resistance, maintaining cutting performance even during extended use in demanding materials. The heavy-duty web construction provides exceptional strength and rigidity at this larger diameter, whilst the precision-engineered 135° split point ensures the bit starts drilling immediately without wandering, providing accurate hole placement with consistent results. Features and Benefits: • 8.5mm diameter ideal for clearance holes and larger fixings • Pack of 5 for professional workshop use • 5% cobalt for superior durability in tough materials • Heavy-duty web for enhanced strength and rigidity • Manufactured to DIN 338 Standards for guaranteed quality Specifications: Tip Diameter (mm): 8.5 Working Length (mm): 75 Overall Length (mm): 117 Pack Qty.: 5 Diameter: 8.5mm.
