Dormer Solid Carbide Drill Bit, 4.2mm Diameter, 66mm Overall Length, 24mm Drilling Length, Titanium Aluminium R4674.2

Dormer R4674.2 solid carbide drill bit with a diameter of 4.2mm, an overall length of 66mm, and a drilling length of 24mm. This drill bit features a titanium aluminium nitride (TiAlN) coating applied to a premium micrograin carbide substrate, offering superior wear resistance and longer tool life under demanding industrial conditions.

The bit has 2 helical flutes designed for efficient chip removal and cooling, enhanced by the coolant-through capability, supporting high-performance drilling. The cylindrical shank of 6mm diameter offers optimal grip and compatibility with a range of power tools.

The cutting geometry includes a 140° drill point angle with an S-shape 4-facet split point providing precise thin edge honing and a strong outer corner design for accuracy and durability. The design complies with DIN 6537 K standards ensuring dimensional consistency.

This drill bit is engineered specifically for drilling stainless steels and heat-resistant superalloys, making it ideal for industrial machining, manufacturing, construction, and automotive applications requiring process reliability and high accuracy. The right-handed cutting direction facilitates smooth penetration and chip evacuation.

Manufactured with high precision engineering and coated with TiAlN for enhanced heat and wear resistance. Designed for high volume drilling with stable dimensional accuracy and process reliability. Coolant-through system reduces heat and improves tool life during continuous use.

Suitable for demanding industrial, manufacturing, and metalworking applications. Compliance with international standard DIN 6537 K guarantees quality and performance. Origin Brazil ensures superior manufacturing standards for solid carbide products.
