## Summary description

Irwin 10502562 is a single-piece twist drill bit with an 8.5 mm diameter designed for general drilling tasks. Suitable for use with electric and cordless drills, it provides straightforward holemaking in common materials. Use for wood, soft metals and plastics where an 8.5 mm bore is required; ideal for repair, assembly and construction jobs.

## Long description

Irwin 10502562 is a single-piece twist drill bit with an 8.5 mm diameter designed for general and demanding drilling tasks. Made from high-speed steel with 5% cobalt, this 8.5 mm drill bit offers increased heat and abrasion resistance compared with standard HSS bits. The 135° split point reduces bit walking and starts cutting immediately, while the reinforced web and cylindrical shank provide strength and stable mounting in electric or cordless drills. With an overall length of 117 mm, the bit is suitable for creating clean, precise 8.5 mm bores in a range of workshop and on-site applications.
Advantages
The Irwin 8.5 mm twist drill bit combines cobalt-enriched HSS material and a heavy-duty web construction to deliver enhanced durability and resistance to heat and wear. The 135° split point improves centering and reduces the need for pilot holes, minimizing slippage on smooth surfaces. Manufactured to DIN 338 standards, the bit provides consistent geometry and reliable performance when drilling alloyed steels, stainless steel and other metals, as well as wood and plastics for general tasks.
Suitable for
 Drilling 8.5 mm holes in alloyed steel and stainless steel
 Workshop repair and assembly of metal components
 On-site construction tasks requiring 8.5 mm bores
 Drilling in wood and plastics for fittings and installations
Key specifications
 Type: single-piece twist drill bit
 Diameter: 8.5 mm
 Overall length: 117 mm
 Material: high-speed steel with 5% cobalt
 Point angle and geometry: 135° split point
 Shank type: cylindrical
 Quantity: 1 piece
How to use
Secure the Irwin 8.5 mm twist drill bit in a compatible drill chuck, ensuring the cylindrical shank is clamped firmly. Select an appropriate drill speed for the material: lower speeds for stainless and hardened steels, medium to higher speeds for softer metals, wood and plastics. Use cutting fluid or lubricant when drilling metals to extend bit life and reduce heat, and apply steady, moderate feed pressure. Clear chips periodically to avoid clogging and overheating. For precise starts on smooth or hardened surfaces, consider using a center punch or pilot hole before drilling.
Usage recommendations
 Use cutting fluid and controlled speeds when drilling stainless or alloyed steels; allow the bit to cool between prolonged cuts to preserve the cobalt-enhanced HSS edge. For non-metal materials, moderate speeds and firm clamping will produce clean holes without excessive heat buildup.
