## Long description

Irwin Twist Drill Bit 8.5 mm (model 10502226) is a single-piece twist drill intended for general-purpose drilling in common workshop and construction tasks.

Key specifications
 Drill type: Twist drill bit, single-piece
 Diameter: 8.5 mm
 Overall length: 117 mm
 Shank type: Triangle shank
 Suitable materials: Metal, sheet metal, plastic, stainless steel (with coolant), wood
 Pack quantity: 1 piece
How to use
Secure the twist drill bit in a compatible chuck or holder that accepts a triangle shank, ensuring firm clamping to prevent slippage. Select an appropriate rotational speed for the material being drilled and apply steady, moderate feed pressure. For metal and sheet metal, use cutting lubricant to reduce heat and improve hole quality. When drilling stainless steel, use coolant and lower speeds to avoid work hardening. Withdraw the bit periodically to clear chips and prevent clogging.
Usage recommendations
Use appropriate personal protective equipment, clamp workpieces securely, and select correct speed and lubrication for the material. For extended life when drilling stainless steel or harder alloys, consider using specifically formulated HSS cobalt drills.
