IRWIN 10502220 drill bit Twist drill bit 1 pc(s)

IRWIN 10502220 is a single-piece twist drill bit with a 5.5 mm cutting diameter designed for general-purpose drilling in metal, sheet metal, plastic and wood. The Turbomax geometry favours high-performance drilling in sheet materials while maintaining effective cutting action in a range of common workshop substrates. The bit features a triangle shank for secure grip in compatible chucks and a total length of 93 mm, making it suitable for routine drilling tasks where a reliable HSS-style bit is required.

Advantages

The twist design provides efficient chip evacuation and consistent hole quality across different materials. Turbomax geometry enhances cutting speed and reduces heat buildup during drilling in sheet metal and similar thin materials. The triangle shank improves torque transfer and minimizes slippage in compatible holders. Supplied as a single unit, the bit is ready for immediate use in standard drilling and hand-held applications.

Suitable for

• Drilling holes in sheet metal and light-gauge steel
• General metalworking tasks in mild steel and non-ferrous metals
• Drilling plastic components and assemblies
• Workshop and on-site wood drilling for dowels and pilot holes
• Occasional drilling of stainless steel with appropriate coolant

Key specifications

• Type: Twist drill bit
• Cutting diameter: 5.5 mm
• Total length: 93 mm
• Shank type: Triangle shank for secure grip
• Recommended materials: Metal, sheet metal, plastic, stainless steel, wood
• Pack quantity: 1 piece

How to use

Mark the drilling point and secure the workpiece to prevent movement. Choose an appropriate drill or holder that accepts a triangle shank and clamp the bit firmly. Start at low speed to establish the cut, then increase speed as appropriate for the material. Apply steady, even pressure and allow the bit to do the cutting without forcing. Clear chips regularly to avoid clogging and overheating.

Usage recommendations

Use cutting fluid or coolant when drilling stainless steel and harder alloys to extend tool life and maintain hole quality. For sheet metal, use the Turbomax geometry at moderate speeds to balance cutting efficiency and control. Replace the bit if wear or chipping is evident to prevent poor hole accuracy and increased motor load.
