DRC3D 03.8xD6x24x66 thru coolant drill

Description

DRC3D 03.8xD6x24x66 is a high-performance 3xD through coolant carbide drill engineered for precision hole machining in hardened and difficult-to-machine materials up to 55 HRC. Designed for professional CNC drilling applications, this solid carbide drill provides excellent dimensional accuracy, cutting stability, and reliable performance in production environments.
Featuring a 3.8 mm drill diameter, 6 mm shank diameter, 24 mm flute length, and 66 mm overall length, the DRC3D provides a 3xD drilling capability suitable for accurate hole-making applications. Its through-coolant design delivers coolant directly through the drill to the cutting zone, helping control cutting temperature, improve chip evacuation, and maintain stable machining conditions during deeper-hole drilling.
The optimized carbide drill geometry supports efficient cutting and smooth chip evacuation while helping to reduce vibration and cutting resistance. This contributes to improved hole accuracy, consistent surface quality, and dependable tool performance. The solid carbide construction provides excellent rigidity and wear resistance for demanding machining operations.
The DRC3D 03.8xD6x24x66 is suitable for drilling hardened steels, tool steels, mould steels, alloy steels, and other suitable materials up to 55 HRC, depending on the workpiece condition and recommended cutting parameters.
Typical applications include die and mould manufacturing, automotive components, precision engineering, tool rooms, machine components, and general CNC machining. It is particularly suitable for VMC and CNC machining centres equipped with through-spindle coolant systems.
With its 3xD drilling capability, through-coolant technology, solid carbide construction, and 55 HRC machining capability, DRC3D 03.8xD6x24x66 provides accurate hole machining, efficient heat management, reliable chip evacuation, and consistent performance for demanding precision drilling applications.
