Dormer Solid Carbide Drill Bit 9 mm Size, 89 mm Overall Length, Titanium Aluminium Nitride Finish R4679.0

Dormer R4679.0 solid carbide drill bit is engineered for high performance and reliability in industrial environments, especially for drilling stainless steels and heat resistant super alloys. This drill bit features a solid carbide construction with a titanium aluminium nitride (TiAlN) coating, enhancing durability against wear and heat.

The drill bit has 2 helical flutes with a unique CTW™ flute construction that includes a continuously thinned web and rolled heel design, improving chip evacuation. It also has an S-Shape 4-Facet Split Point with precise thin edge honing and a robust outer corner design to ensure high accuracy and long tool life.

With a drill bit size of 9 mm, overall length of 89 mm, and drilling length of 47 mm, it is suitable for demanding drilling tasks. The cylindrical shank of 10 mm ensures secure grip in compatible drill chucks. The drill point angle is 140°, optimized for right-hand cutting direction. The coolant-through feature allows internal coolant feeding, reducing heat build-up and extending tool life during intensive drilling.

This drill bit conforms to DIN 6537 K standards and is manufactured in Brazil, utilizing premium micrograin carbide substrate combined with TiAlN coating for superior performance in industrial machining, metalworking, and manufacturing processes.
