## Long description

Irwin 10502561 is a single-piece twist drill bit with an 8 mm cutting diameter, designed for drilling round holes in a range of materials. The bit features spiral (twist) geometry and is intended for use in handheld drills and drill presses for general drilling tasks where a single 8 mm bit is required. Constructed to meet demanding workshop needs, this Irwin twist drill bit combines core design features for stable drilling performance.
Advantages
The 8 mm Irwin twist drill bit offers high heat and abrasion resistance due to a cobalt-enhanced high-speed steel composition, improving durability during prolonged use. Its heavy-duty web construction increases strength at the bit core to resist breakage under load. The 135° split point geometry reduces bit walk and starts cutting immediately for more accurate hole placement. Manufactured to DIN 338 standards, the bit provides consistent geometry and dimensions suitable for precise drilling operations.
Suitable for
Drilling round holes with an 8 mm diameter in metal and other machinable materials
Use in handheld electric drills and drill presses
General workshop and maintenance drilling tasks requiring a single 8 mm bit
Key specifications
Cutting diameter: 8 mm
Geometry: twist (spiral) flute
Point angle: 135° split point
Material: high-speed steel with cobalt additive (approximately 5% cobalt)
Construction: single-piece, heavy-duty web
Manufacturing standard: DIN 338
How to use
Secure the Irwin 8 mm twist drill bit in the drill chuck and ensure it is centered and tightened. Select an appropriate drill speed for the material being drilled and apply steady, even pressure while keeping the drill perpendicular to the workpiece. For metal drilling, use cutting lubricant to reduce heat and prolong bit life. Withdraw the bit periodically to clear chips when drilling deeper holes, and reseat workpieces or clamps as needed to maintain stability.
Usage recommendations
For best results when drilling hardened or abrasive alloys, operate the drill at moderate speed with appropriate coolant or cutting oil, maintain steady feed pressure, and replace the bit if wear or chipping appears. Store the bit in a dry, protected holder to avoid damage to the cutting edges.
