Solid carbide drills VHB 55505 DR20.
The tool programme has been especially developed for drilling different steels, high grade steels and cast iron materials. It offers a high productivity also for high feed rates and cutting speeds, by maintaining a very good drill hole quality and surface quality.
The tools can be adopted for milling and for turning machines and thanks to the universal design they can be adopted for almost all drilling operations.
The mounting shank is made to DIN 6535-HA, a subsequent application of clamping surfaces made to DIN 6535-HB (Weldon) or –HE (Whistle-Notch) is possible.
The tools are available in diameter range from 2,0 mm up to 20,0 mm, in the length 5xD. Up to diameter 10,0mm they are available in 1/10 gradations.
