Dormer Solid Carbide Drill Bit 4.2 mm Size, 74 mm Overall Length, 36 mm Drilling Length, TiAlN Coated, Helical Flutes R4634.2

Dormer R4634.2 solid carbide drill bit is engineered for industrial and mechanical applications requiring high performance and process reliability. With a drill bit size of 4.2 mm and an overall length of 74 mm, it is ideal for precision drilling tasks. The drill bit features a helical 2-flute design coated with titanium aluminium nitride (TiAlN) for enhanced hardness and wear resistance, extending tool life under demanding conditions.

This drill bit includes coolant through capabilities, allowing effective cooling during operation, which maintains tool temperature and prevents overheating. The right cutting direction combined with a 140° drill point angle provides sharp and efficient penetration into stainless steel and heat-resistant super alloys, making it suitable for metalworking industries.

The shank is cylindrical with a diameter of 6 mm, compatible with standard drill chucks for versatile use. The drilling length of 36 mm allows precision hole depths with consistent accuracy. Manufactured in Brazil and meeting DIN 6537 K standards, this drill bit ensures reliable mechanical strength and dimensional stability.

Special features include CTW™ unique flute construction with a continuously thinned web and rolled heel design and an S-Shape 4-facet split point with precise thin edge honing for superior cutting and chip evacuation performance. The premium micrograin carbide substrate with TiAlN coating provides excellent resistance to wear and heat.

Applications include industrial machining, manufacturing, metal fabrication, and tooling operations requiring durable, high-precision drill bits capable of handling tough materials. This product is part of Dormer's FORCE M series designed to maintain high accuracy during large volume drilling operations.
