Bosch 2607017154 HSS Twist Drill Bit Set 25-Piece TiN Coated Cylindrical Shank

This 25-piece HSS twist drill bit set from Bosch delivers precision drilling across metal, plastic, and wood. The titanium nitride (TiN) coating reduces friction and heat, extending bit life and enabling faster drilling. Each bit features a 118° point angle and cylindrical shank for secure chuck grip, making the set ideal for both cordless and corded drills.

Advantages

TiN coating provides a hard, wear-resistant surface that lowers friction, allowing higher drilling speeds and longer service life. The rolled manufacturing process ensures consistent flute geometry for efficient chip removal. The set includes 25 diameters from 1.0 mm to 13.0 mm in 0.5 mm increments, covering most common drilling tasks. A robust metal case keeps bits organized and protected.
