## Summary description

## Long description

The Irwin Twist Drill Bit 10502399 is a precision-ground metalworking drill with an 11 mm diameter (1.1 cm) supplied as a single piece for workshop and construction use. Manufactured to DIN 338 standards with a reduced shank and ground flute, this twist drill bit features a universal 118° point geometry and precision-ground cutting edges to deliver accurate holes and efficient chip evacuation across a range of common materials.
Advantages
Designed to meet DIN 338 requirements, the drill bit offers consistent dimensions and long-lasting cutting performance. The precision-ground cutting edges and ground flute ensure fast drilling, clean hole finish and improved centring, while the reduced shank provides compatibility with chucks that accept slightly larger shank diameters. The universal 118° point is suitable for general-purpose drilling, and the cylindrical shank gives stable clamping in standard drill chucks.
Suitable for
Drilling round holes in plastic components
Drilling soft metals such as aluminium and non-ferrous alloys
General-purpose drilling in wood and composite materials

How to use
Install the Irwin 11 mm twist drill bit securely in a compatible drill chuck and tighten according to the drill manufacturer's instructions. Select an appropriate rotational speed and feed rate for the material being drilled—lower speeds for harder metals and higher speeds for plastics and wood. Use steady, even pressure to avoid wandering; withdraw periodically on deeper holes to clear chips and reduce heat buildup. Ensure proper clamping of the workpiece and wear suitable personal protective equipment when drilling.
Usage recommendations
For best results, apply cutting fluid or lubricant when drilling soft metals to prolong tool life and improve surface finish. For plastics, use moderate speeds and reduced feed to prevent melting; when drilling wood, ensure stable workpiece support and use dust extraction if available.
