Dormer High Speed Cobalt Drill Bit 8.5 mm Size, 79 mm Overall Length A9208.5

Dormer A9208.5 High Speed Cobalt Drill Bit, size 8.5 mm with an overall length of 79 mm, is engineered for industrial and mechanical applications requiring high precision and durability. This drill bit is suitable for machining deep holes up to three times the diameter in a variety of materials, benefiting from the cobalt material composition for enhanced heat resistance during prolonged use.

The drill bit has a bright, uncoated finish and is equipped with three helical flutes designed to optimize chip evacuation, reducing the risk of clogging and increasing drilling efficiency. Its parabolic flute design allows for greater drilling depths without the need for intermittent withdrawal ('pecking'), enhancing workflow speed and tool longevity.

Its 130-degree special point geometry improves centring accuracy and reduces thrust force, which helps prevent bit walking and breakage. The thicker web design of this bit increases structural strength, minimizing breakage risk during demanding drilling tasks. The cylindrical shank provides secure fitting in standard drill chucks, ensuring reliable performance.

This drill bit conforms to DIN 1897 standards, underscoring its quality and precision manufacturing.

Ideal for industrial sectors such as metal fabrication, manufacturing, construction, and mechanical repair shops, this Dormer high speed cobalt drill bit performs reliably across a range of materials requiring precise, deep hole drilling.
