## Long description

Irwin 10502402 is a single-piece twist drill bit with a 12.5 mm diameter designed for general-purpose drilling with handheld or bench drills. Manufactured to DIN 338 standards and ground to high quality, this drill bit features a reduced shank and a universal 118° point shape that supports accurate, guided cutting and effective chip evacuation via precision-ground flutes.
Advantages
The precision-ground cutting edges and ground flute deliver fast drilling and a clean finish while maintaining dimensional accuracy. The reduced shank allows the 12.5 mm diameter bit to fit a wider range of drill chucks, and the universal 118° point is optimized for drilling into plastics, soft metals and wood. Manufactured to DIN 338 standards, the tool provides consistent quality suitable for routine workshop and site tasks.
Suitable for
Drilling 12.5 mm holes in plastic components
Creating holes in soft metals such as aluminium or brass
Working with wood for joinery or through-holes
Use with handheld and bench drills where a cylindrical shank is required
Key specifications
Type: twist drill bit, single piece
Diameter: 12.5 mm
Overall length: 151 mm
Point angle: 118° (universal)
Shank: cylindrical, reduced shank design
Flute: precision ground spiral for fast chip removal
Standards: manufactured to DIN 338
Recommended materials: plastic, soft metal, wood
How to use
Secure the drill bit in the chuck of a handheld or bench drill, ensuring the reduced shank seats fully for concentric running. Select an appropriate rotation speed for the material: moderate speeds for plastics, higher speeds for soft metals with light feed, and medium speeds for wood. Begin drilling with steady, axial pressure and allow the precision-ground flutes to evacuate chips; retract periodically when drilling deeper holes to clear chips and avoid heat buildup. Use cutting fluid when drilling soft metals to extend tool life and improve finish.
Usage recommendations
For best results, match drill speed and feed to the material, keep the bit cool when working with metals, and inspect the cutting edges before use. Store the bit in a protective case to prevent damage to the precision ground edges.
