WIDIA Erickson Taper Face Contact Shank Tooling System BTKV40 Series Erickson Taper Face BT Contact Taper Tooling is manufactured from premium materials and to the latest JIS B 6339 specification standard with an AT3 7/24 Taper per IS0-1974. Controlled, increased flange thickness to the rear of the flange gains face contact between spindle and holder. The BTKV40 tools are prebalanced to a high specification that will perform effectively up to 20,000 RPM. For any applications higher than 20,000 RPM, WIDIA recommends that the complete toolholder assembly (toolholder, retention knobs, collets, hardware, and cutting tools) be balanced as one identity. JIS B 6339 7/24 taper. Standard M16 metric drawbar thread. High axial repeatability due to face contact. High radial positioning due to controlled, tighter drive key widths. All tools set to form AD coolant specification. Many can be converted to form B style. Maximum 20,000 RPM. Maximum 100 bar (1,500 psi) coolant pressure.
