BOSCH PRO Twist Drill Bit Set, Cobalt High-Speed Steel, 19-Piece

The Bosch Professional Stainless Steel 19-piece HSS-Co Twist Drill Bit Set is a metal-drilling accessory set for stainless steel and other steels. It contains dedicated twist drill bits rather than a mixed selection of drilling and driving accessories. The bits are made from high-speed steel with added cobalt, which improves heat resistance and durability during demanding metal-drilling work. The set is designed for clean, accurate holes where control in steel matters.

Each bit has a centring tip that establishes the starting point more precisely and reduces wandering as the bit begins to cut. The set is intended for rotary drills and drill/drivers, so it can be used with either tool type. The carrying case keeps the selection together for organised storage and transport between jobs. Intended users include construction workers, installers and maintenance professionals who regularly drill steel. The scope is specifically metal drilling, not a general mixed-accessory assortment.
