Product Description

Dormer A9204.2 high speed cobalt drill bit offers a 4.2mm shank size and an overall length of 55mm. This drill bit is specifically designed for precise and deep hole machining in a wide range of materials commonly found in industrial and mechanical environments.

Manufactured from high speed cobalt (HSCo), this drill bit provides excellent durability and higher heat resistance compared to standard drills, allowing for sustained performance during prolonged use.

It features 3 helical flutes with a parabolic design to facilitate rapid chip evacuation, enabling drilling depths up to three times the diameter without the need for pecking, enhancing efficiency and reducing downtime. The 130° special point geometry improves centring capability and lowers thrust, which aids in smoother operation and better hole accuracy.

The cylindrical bright (uncoated) shank with a 4.2mm diameter ensures compatibility with most drilling machines with a right cutting direction for general application versatility. Its thicker web design increases structural strength, significantly reducing the risk of drill breakage during heavy-duty machining tasks.

Compliant with DIN1897 standards, this drill bit is a reliable choice for workshop, manufacturing, HVAC, automotive, and fluid power applications where precision and durability are critical.
