BOHRCRAFT Drill Bits – 1149 HSS-E Cobalt 5% Drill Bits with 3 Cutting Edges

The BOHRCRAFT 1149 HSS-E Cobalt Drill Bits are professional-grade cutting tools designed for precision drilling in alloyed steels, stainless steels (INOX), cast steel, and other tough materials. Manufactured from HSS-E cobalt (5% cobalt alloyed high-speed steel), they deliver superior heat resistance, wear resistance, and durability under demanding conditions.

With a 3-flute/3-cutting edge geometry, these drill bits provide smoother cutting, faster chip removal, and improved hole quality compared to standard 2-flute designs. This results in cleaner holes, reduced vibration, and longer tool life.

Specifications:

• Brand/Series: BOHRCRAFT 1149
