Dormer High Speed Cobalt Drill Bit, 3.5mm Shank Size, 70mm Overall Length, Helical 6-Flute, Cylindrical Shank, 130° A9003.5

Dormer A9003.5 High Speed Cobalt Drill Bit is a precision-engineered tool featuring a 3.5mm shank size and 70mm overall length. Constructed from high speed cobalt material, it delivers excellent durability and heat resistance for heavy-duty drilling applications.

This drill bit incorporates a helical 6-flute design with a bright uncoated finish to facilitate rapid chip evacuation and clean drilling. Its cylindrical shank type offers secure tool mounting, while the 130° drill point angle ensures superior centring and reduces axial thrust during operation.

Designed for right-hand cutting direction, this drill bit excels in machining deep holes up to six times its diameter without the need for peck drilling. The thicker web design enhances structural strength, minimizing the risk of breakage during demanding industrial use.

Manufactured to DIN338 standards, the A9003.5 model meets stringent quality requirements suitable for industrial, mechanical, construction, and manufacturing applications. It is widely used in metalworking and fabrication tasks requiring precision and robustness.
