Twist drill bit Irwin 10502222, 6.5 mm diameter, 1 pc

Irwin twist drill bit model 10502222 with a 6.5 mm diameter is a single-piece cutting tool intended for general-purpose holemaking. Supplied as one drill bit, it fits compatible drills with a triangle shank and is suitable for workshop, repair and maintenance tasks where a 6.5 mm bore is required. The straight-fluted design supports effective chip evacuation when drilling common materials including metals, plastics, sheet metal and wood.

Advantages

The Irwin 6.5 mm twist drill bit offers predictable drilling performance across a range of materials and a compact overall length of 101 mm for good control in handheld and bench drilling operations. The triangle shank helps secure the bit in chucks or holders designed for non-round shanks, reducing slippage. Supplied as a single unit, it is convenient for occasional replacements or targeted maintenance work.

Suitable for

• Drilling holes in metal sheets and general metalwork
• Creating 6.5 mm bores in plastic components
• Workshop and maintenance tasks requiring a single replacement bit
• Drilling into wood for fittings and fasteners

How to use

Install the 6.5 mm Irwin twist drill bit into a compatible drill or holder designed to accept a triangle shank, ensuring it is clamped securely. Select an appropriate drill speed for the material being worked: higher speeds for wood and plastics, moderate speeds for general metals, and lower speeds for stainless steel. Apply steady, even pressure and allow the bit to cut without forcing; withdraw periodically to clear chips when drilling deeper holes. For through-holes use backing support where possible to reduce burrs on exit.

Usage recommendations

When drilling stainless steel or other hard alloys, use cutting fluid or coolant and reduced speed to extend bit life and maintain hole quality. For sheet metal, clamp the workpiece and support thin sections to prevent deformation. Replace the bit if cutting performance degrades or if visible wear or chipping appears on the cutting edges.
