## Long description

Irwin 10502403 is a single twist drill bit with a nominal diameter of 1.3 cm designed for general drilling tasks. The bit is precision ground and manufactured to DIN 338 standards with a reduced shank and a universal 118° point shape. It features ground cutting edges and a ground flute to ensure fast drilling, accurate hole placement and efficient chip removal when used in compatible drill machines.
Advantages
The precision ground cutting edges and ground flute provide fast penetration and accurate hole finishing. Conformance to DIN 338 standards and a reduced shank improve compatibility with a wide range of chucks and drill machines. The universal 118° point shape makes the bit suitable for varied materials, while the cylindrical shank ensures secure mounting and stable drilling performance.
Suitable for
Drilling holes in soft metals (aluminium, brass)
Drilling holes in plastics and composite materials
Woodworking tasks requiring clean entry and exit holes
General repair, maintenance and assembly operations
Key specifications
Type: Twist drill bit (spiral)
Nominal diameter: 1.3 cm
Overall length: 151 mm
Point angle: 118° (universal)
Shank type: Cylindrical, reduced shank design
Flute: Ground flute for efficient chip evacuation
Cutting edges: Precision ground
Pack quantity: 1 piece
How to use
Select a drill machine with a chuck compatible with the cylindrical reduced shank and secure the bit firmly in the chuck. Set the drill speed appropriate for the material: lower speeds for metals, medium speeds for plastics and higher speeds for wood. Align the bit perpendicular to the work surface, start drilling with light pressure to create a pilot indentation, then increase steady pressure until the hole is complete. Withdraw the bit periodically when drilling deep holes to clear chips and avoid overheating.
Usage recommendations
Use cutting lubricant or coolant when drilling metals to extend bit life and reduce heat buildup. For clean holes in wood and plastics, clamp the workpiece and consider using a backing board to prevent splintering on exit. Inspect the bit before use and replace it if cutting edges are worn or damaged.
