Dormer Solid Carbide Drill Bit 3.3 mm Size, 66 mm Overall Length, 6 mm Shank, Titanium Aluminium Nitride Finish R4633.3

Dormer R4633.3 solid carbide drill bit measuring 3.3 mm in diameter with an overall length of 66 mm is engineered to deliver high performance drilling in demanding materials such as stainless steels and heat resistant super alloys. This drill bit is a reliable tool for industrial, manufacturing, metalworking, and construction applications requiring precise and consistent accuracy.

The tool features a premium micrograin carbide substrate coated with titanium aluminium nitride (TiAlN) that provides excellent wear resistance and longer tool life. The 2-flute helical design with unique CTW™ flute construction ensures optimized chip evacuation and reduces cutting forces. Its 140° drill point angle and S-Shape 4-Facet split point with thin edge honing improves hole quality and reduces walking.

This drill bit supports coolant through functionality which helps maintain lower operating temperatures to extend tool life and improve machining efficiency. It has a 6 mm cylindrical shank that fits most standard drilling machines and is crafted according to DIN 6537 K standards. Manufactured in Brazil with stringent quality controls and designed for medium to high volume drilling requiring repeatability and precision.
