Weldonfutter SK 40 DIN 69871

Surface chucks for Weldon shafts are suitable for gripping milling cutters with cylindrical shaft and side pulling faces per DIN 1835-B and DIN 6535-HB. The tool mount SK 40 DIN 6987 (new: DIN ISO 7388-1) is the interface between cutter spindle and tool. It stands out for its extremely tough construction and wide range of application, all the way from fine machining to heavy metal working. Gripping in the cutter spindle is accomplished with a draw bolt, which can be ordered separately. The tapered surfaces allow for centering, making it suitable for applications at rotation speeds of up to 12,000 rpms.
