Dormer High Speed Cobalt Spiral Flute Drill Bit 5 mm Shank Size, 132 mm Overall Length A9405.0

Dormer A9405.0 high speed cobalt spiral flute drill bit with a 5 mm shank size and 132 mm overall length is engineered for precise, deep hole drilling tasks in industrial and mechanical environments.

This drill bit is constructed from premium high speed cobalt material, providing exceptional hardness and heat resistance for prolonged tool life even under heavy-duty machining conditions.

The 10 spiral flutes feature a parabolic design, facilitating rapid chip evacuation and enabling drilling depths of up to 10 times the bit diameter without frequent pecking. The 130° special drill point angle enhances centring capability and reduces thrust force, improving drilling accuracy and operator efficiency.

The cylindrical shank features a bright, uncoated finish that ensures reliable gripping in drill chucks or holders. A thicker web design increases structural strength, substantially reducing the risk of drill bit breakage during operation.

Manufactured according to DIN 340 standards, this drill bit guarantees consistent quality, performance, and compatibility with industry tooling systems.

Ideal for demanding drilling applications across industrial manufacturing, mechanical workshops, fluid power maintenance, and general power tool operations, this drill bit delivers outstanding results on most materials requiring high precision.
