Dormer High Speed Cobalt Drill Bit 1.59 mm, 76 mm Overall Length, 1.6 mm Shank, Spiral Flute, Cylindrical Shank A9401/16

Dormer A9401/16 High Speed Cobalt Drill Bit, size 1.59 mm with 76 mm overall length, is designed for industrial and manufacturing drilling applications demanding precision and durability.

This drill bit features a parabolic flute design with 10 spiral flutes that provide rapid chip evacuation, enabling drilling of deep holes up to ten times the diameter with improved efficiency. The 130° special point geometry enhances centring capability and reduces thrust force required during machining.

Constructed from high speed cobalt material, the bit delivers excellent heat resistance and longevity when drilling various materials. The cylindrical 1.6 mm shank assures stable mounting in drill chucks or machines.

The bright uncoated finish ensures smooth operation with reduced friction. Manufactured in Brazil as per DIN340 standards, the bit stands out for structural strength due to a thicker web design lowering drill breakage risk.

High speed cobalt material provides excellent heat resistance and wear life. Ten spiral flutes facilitate quick chip removal and prevent clogging. Parabolic flute design allows deeper drilling without pecking. 130° drill point angle aids in precision centring and reduced thrust.

Cylindrical shank for firm holding in various drilling equipment. Bright, uncoated finish assures high cutting performance. Thicker web design enhances structural strength and durability. Suitable for industrial, manufacturing, and mechanical workshop use.

Produced according to DIN340 standards ensuring quality assurance.

This Dormer drill bit is essential for precision drilling in mechanical workshops, manufacturing plants, and fluid power tool applications requiring accurate hole sizes and efficient metal cutting.
