Dormer High Speed Cobalt Drill Bit, 89 mm Overall Length, 10.2 mm Shank Size A92010.2

Dormer A92010.2 High Speed Cobalt Drill Bit is a premium-grade tool engineered for demanding industrial and manufacturing applications requiring precision deep-hole drilling. It features a high-speed cobalt composition that offers exceptional hardness and resistance to wear, useful for drilling various materials with minimal tool degradation.

The drill bit has a total length of 89 mm with a cutting length (drilling length) of 43 mm, providing capability for deep hole machining up to three times the diameter of the drill size. Its cylindrical shank design with a diameter of 10.2 mm ensures secure chuck fitting and reliable torque transfer.

The parabolic flute design facilitates rapid chip evacuation to prevent clogging, allowing continuous and efficient drilling operations. The 3-flute helical configuration supports smooth material removal and reduces heat buildup, prolonging tool life.

Its bright uncoated finish helps decrease friction and heat generation, while the right-hand cutting direction and 130° drill point angle provide excellent centring for accurate hole placement and reduced thrust. The thicker web design enhances the structural integrity of the drill, significantly lowering the risk of breakage during heavy-duty use.

Manufactured to DIN1897 standards, this drill bit guarantees precision and consistent quality required in industrial, mechanical, fluid power, and tool-making environments. It is suitable for use in workshops, manufacturing plants, and maintenance settings where reliability and performance are critical.
