## Summary description

Irwin 10502273 is a 10-piece drill bit set with each bit sized 4.2 mm in diameter. Designed for drilling tasks, the set provides multiple identical bits for consistent hole dimensions.

## Long description

Irwin 10502273 — 10 pcs, 4.2 mm diameter drill bit set provides a compact selection of identical twist drills for tasks that require consistent 4.2 mm holes. Each bit is precision ground and manufactured to DIN 338 standards with a cylindrical shank and a universal 118° point geometry, making the set suitable for general-purpose drilling in a range of common workshop and site situations.
Advantages
The set contains ten identical 4.2 mm bits packaged in a Quadro Pack for easy storage and transport. Ground-quality construction and precision-ground cutting edges ensure fast drilling and clean hole finishes, while the ground flute geometry promotes rapid chip evacuation and accuracy. Cylindrical shanks allow secure clamping in standard chucks and compatibility with many hand drills and drill presses.
Suitable for
 Drilling 4.2 mm holes in wood for joinery or fittings
 Creating holes in plastics for assembly or mounting
 Light drilling in soft metals such as aluminium for maintenance tasks
 Repetitive tasks where multiple identical bits reduce downtime
Key specifications
 Drill type: twist drill bits (set of 10)
 Diameter: 4.2 mm
 Overall length: 75 mm
 Point angle: 118° universal point
 Shank type: cylindrical shank
 Material/finish: ground-quality, precision ground cutting edges
 Flute: ground flute for fast chip removal and accuracy
How to use
Select an appropriate drilling speed and clamp the workpiece securely. Fit a 4.2 mm bit from the set into the drill chuck, ensuring the cylindrical shank is seated and tightened. Use steady, moderate pressure and allow the bit to cut rather than forcing it; retract occasionally on deeper holes to clear chips. For metal drilling, use cutting fluid or lubricant as appropriate; for wood and plastic, lower speeds often give cleaner results.
Usage recommendations
Use the Irwin 4.2 mm bits for routine maintenance, installation and light construction tasks. Match drill speed and feed to the material: higher speeds for wood and plastic, lower speeds with lubrication for soft metals. Replace bits showing wear or chipping to maintain hole quality and reduce risk of heat buildup.
