BOSCH 2607017152 Titanium Nitride-Coated High-Speed Steel Metal Drill Bit Set, 19 Pieces, 1–10 mm

The BOSCH 19-piece HSS-TiN metal drill bit set is a collection of twist drills for producing accurate holes in metal. Every bit uses high-speed steel with a titanium nitride coating, combining the base alloy and surface treatment across the set. It is intended for drilling steel, cast iron and other metals. The coating helps reduce friction and wear during drilling while increasing resistance to heat. Compared with uncoated standard bits, this construction is specified to provide a longer service life.

Each bit has a cylindrical shank for use with compatible electric drills and drill drivers. The selection is intended for professional metalworking and maintenance as well as workshop and DIY drilling tasks. Its spread of diameters supports jobs requiring more than one hole size without switching to another set. An included carrying case keeps the drill bits together between tasks. The compact storage format suits a workbench, tool cupboard or transport alongside a compatible drill.

• 1–10 mm size range progresses in 0.5 mm increments.
• 135° point angle helps each bit centre accurately and start drilling cleanly.
• DIN 338 N-type design specifies the drill bit geometry.
• 448 g total weight includes the set and its storage case.
• Plastic case provides a dedicated container for the complete drill bit selection.
