Twist drill bit Irwin 10502397 — diameter 10 mm, 1 piece

Irwin twist drill bit 10502397 with a 10 mm diameter is a single-piece, precision-ground tool designed for general-purpose drilling with handheld and stationary drills. Manufactured to DIN 338 standards, this twist drill offers a cylindrical shank and a universal 118° point suitable for a wide selection of materials. The ground flute and precision-cutting edges ensure fast drilling, accurate hole placement and a clean finish for routine workshop tasks where a reliable 10 mm hole is required.

Advantages

The drill is ground for high concentricity and consistent performance. Precision ground cutting edges reduce cutting forces and improve hole quality, while the ground flute promotes efficient chip evacuation and reduces clogging. Compliance with DIN 338 standards and a cylindrical shank make the bit compatible with most chucks and provide predictable mechanical properties and dimensional accuracy.

Suitable for

• Drilling 10 mm diameter holes in plastic components
• Creating holes in soft metals such as aluminum and brass
• General woodworking tasks requiring a 10 mm bore
• Routine workshop and maintenance drilling with portable or bench drills

How to use

Select an appropriate drill speed and feed for the work material and secure the workpiece before drilling. Fit the cylindrical shank into a compatible drill chuck and tighten firmly. Start drilling at low speed to establish a pilot entry, then increase speed according to material recommendations. Use light, steady pressure; withdraw occasionally to clear chips if drilling deep holes. After use, clean chips from the flute and store the bit in a protective holder to maintain the ground cutting edges.

Usage recommendations

Use coolant or compressed air when drilling soft metals to extend tool life and improve chip removal. For plastics, use lower speed to avoid melting; for wood, ensure stable clamping to prevent tear-out. Inspect the cutting edges periodically and replace the bit when wear degrades hole quality.
