Dormer Solid Carbide Titanium Aluminium Nitride Coated Drill Bit 6.5mm Size, 79mm Overall Length, Cylindrical Shank R4586.5

Dormer R4586.5 solid carbide drill bit is engineered for accuracy and efficiency in high performance machining processes. With a 6.5mm drill bit size and a total length of 79mm, it is suited for precision drilling in a wide range of industrial and manufacturing applications.

The drill bit is made from high-quality solid carbide material, which offers excellent hardness and toughness, making it ideal for machining hard metals. The Titanium Aluminium Nitride (TiAlN) coating improves wear resistance and heat tolerance, enabling increased productivity and extended tool life.

This model features three helical flutes designed for optimum chip evacuation, allowing higher feed rates during operation. The drill point angle is 140°, optimized for reduced thrust force and improved centering. It supports coolant-through machining, enhancing cooling and lubrication directly at the cutting edge.

The shank is cylindrical and measures 8mm in diameter, compatible with standard tool holders. The cutting direction is right-hand, suitable for conventional drilling operations. Compliance with DIN 6535 HA and DIN 6537 K standards assures precise manufacturing tolerances and consistent performance.

This drill bit is ideal for applications in industries such as automotive manufacturing, aerospace, tooling, and general machining where reliability and precision are critical. Its robust design supports machining up to three times the diameter for versatile use cases.
