Dormer Cobalt Steel Drill Bit 2.5mm Diameter, 57mm Overall Length, 10 Pieces A7772.5

Dormer A7772.5 cobalt steel drill bit set consists of 10 professional-grade HSCo jobber drill bits with a diameter of 2.5mm and an overall length of 57mm. This set is engineered for drilling higher tensile and tougher materials with precision and durability.

The drill bits feature a bronze surface treatment which provides excellent wear resistance, supporting applications within industrial, manufacturing, and mechanical sectors. With 4 helical flutes, the bits ensure efficient chip evacuation and maintain smooth operation during drilling.

Each bit is designed with a right-hand spiral cutting direction and a 135° drill point angle to produce cleaner holes with minimal walking. The cylindrical/straight 2.5mm shank type makes these bits compatible with most standard drill chucks.

Certified to DIN 338 standards, these cobalt steel bits are intended for demanding applications in metalworking, automotive, construction, and general industrial use. The drilling length of 30mm provides versatility for various machining tasks requiring precise hole depths.

This set of 10 bits originates from France, reflecting quality European manufacturing processes. Its robust design supports prolonged use and superior performance in professional environments.
