Twist drill bit Irwin 10502405 — diameter 1.4 cm, 1 pc

Irwin 10502405 is a single twist drill bit with a 1.4 cm diameter designed for general drilling tasks. Manufactured to DIN 338 standards with precision ground cutting edges and a ground flute, this drill bit delivers accurate holes and reliable chip evacuation. The reduced shank and cylindrical design allow use in drills that accept this shank type, and the universal 118° point geometry is suitable for drilling a range of common materials.

Advantages

The drill bit is precision ground to provide fast drilling and a smooth finish while the ground flute improves chip removal and dimensional accuracy during use. Compliance with DIN 338 ensures consistent geometry and performance. The universal 118° point shape and reduced shank increase versatility across different materials and chuck types, while the single-piece supply makes it convenient for replacement or one-off tasks.

Suitable for

• Drilling holes in plastic components
• Creating pilot or clearance holes in soft metals
• Woodworking tasks requiring clean, accurate holes
• General maintenance and repair work with compatible drills

How to use

Secure the drill bit in a compatible drill chuck ensuring the reduced cylindrical shank is firmly clamped. Select an appropriate rotational speed and feed for the material being drilled: lower speeds for metals, higher speeds for plastics and wood, and use steady, even pressure. For metal drilling, apply cutting fluid or lubricant where appropriate to extend tool life and improve chip evacuation. After drilling, retract the tool carefully to clear chips from the hole and inspect the hole for dimensional accuracy and surface finish.

Usage recommendations

Use personal protective equipment such as safety glasses and gloves when drilling. Match drill speed and feed to the material, and avoid excessive axial load to reduce wear. Store the drill bit in a dry place and protect the cutting edges to maintain performance.
