BOHRCRAFT Drill Bits – 1149 HSS-E Cobalt 5% Drill Bit Set, 3 Cutting Edges (4 / 5 / 6 / 8 / 10mm)

The BOHRCRAFT 1149 Drill Bit Set includes a selection of premium HSS-E cobalt (5% cobalt alloyed high-speed steel) drill bits with 3 cutting edges for smoother, faster, and more precise drilling. Designed for stainless steels (INOX), alloyed steels, cast steel, and other difficult-to-machine materials, these bits deliver outstanding heat resistance, wear resistance, and durability.

The 3-flute geometry ensures improved chip evacuation, reduced cutting forces, and cleaner hole quality compared to conventional 2-flute bits. This set covers the most commonly used sizes, making it versatile for workshops, fabrication, and professional machining.
