Bosch 2609255063 HSS-R kierreporanterä 2 mm x 49 mm DIN 338 metallille

The Bosch 2609255063 is a roll-forged HSS-R twist drill bit with a 2 mm diameter, built for clean, accurate holes in unalloyed steel, alloyed steel, cast iron, stainless steel, and non-ferrous metals. Its 118° point angle and black oxide finish reduce friction and improve chip evacuation, while the cylindrical shank fits standard drill chucks. With a 49 mm overall length and 29 mm working length, it reaches into tight spots without sacrificing stability. DIN 338 compliance ensures consistent geometry and reliable performance across production runs.

Highlights

• HSS-R (High-Speed Steel, Roll-Forged) for durability and heat resistance
• 118° standard point angle for accurate centering and reduced walking
• Black oxide surface finish for improved wear resistance and corrosion protection
• Cylindrical shank for secure grip in keyed and keyless chucks
• DIN 338 standard for consistent quality and compatibility

In daily use

This bit excels in general metal drilling tasks—from thin sheet metal to medium steel sections. The 2 mm diameter is ideal for pilot holes, small fasteners, and precision work. The 29 mm working length provides ample depth for most applications while maintaining rigidity. Right-hand cutting rotation matches standard drill rotation. For best results, use cutting fluid on steel and stainless steel, and reduce speed on harder materials.
