Drill bit set Irwin 10502251 — 10 pcs, 2 mm diameter

Irwin 10502251 — 10 pcs, 2 mm diameter drill bit set is designed for precise small-diameter drilling with handheld and stationary drills. The set includes ten 2 mm bits manufactured to DIN 338 standards with precision-ground cutting edges and a universal 118° point for effective drilling across a variety of common workshop materials. Each bit features a cylindrical shank and ground flute geometry to support fast chip removal and consistent hole quality in plastics, soft metals and wood.

Advantages

The bits are precision ground for accurate cutting and smooth finishes, reducing the need for secondary deburring. A universal 118° point shape enables straightforward centering and reliable starts in many materials. Ground flutes improve chip evacuation and help maintain hole accuracy during extended use. Packaged as a compact ten-piece quadro pack, the set offers organized storage and quick access to spare bits for repetitive drilling tasks.

Suitable for

• Drilling small holes in plastic components
• Precision drilling in soft metals such as aluminum and brass
• Fine woodworking and trim work requiring 2 mm pilot holes
• General workshop and DIY applications where small-diameter holes are needed

• Intended materials: plastics, soft metals, wood

How to use

Select a properly sized drill chuck for the cylindrical shank and secure the bit tightly to avoid runout. Start drilling at low speed to establish the hole and then increase speed as appropriate for the material—lower speeds for metals, higher speeds for plastics and wood—while applying steady, moderate feed pressure. Use cutting fluid when drilling metals to extend bit life and improve finish. After drilling, retract the bit intermittently to clear chips and reduce heat buildup.

Usage recommendations

For best results, mount the bit in a well-maintained chuck and use appropriate rotational speed for the material. Keep the bits clean and store them in the supplied pack to prevent damage. When drilling metals, use lubricant and avoid excessive pressure to maintain edge life and hole quality.
