BOHRCRAFT Drill Bits – 1203 TURBO Step Twist Drill Bits, HSS-E Co5, for Steel

The BOHRCRAFT 1203 TURBO Step Twist Drill Bit is a high-performance cutting tool engineered for precision drilling in alloyed and unalloyed steels, stainless steels, and other tough materials. Manufactured from HSS-E Co5 (high-speed steel with 5% cobalt), it offers excellent heat resistance, durability, and cutting efficiency even under heavy-duty conditions.

The innovative TURBO step profile reduces drilling forces, improves centering, and allows for faster, smoother drilling with extended tool life.
