PL BT (Dual Contact Holder)

PLBT is the designation for the BIG-PLUS BT taper, and BCV is the designation for the taper. Conventional steep taper tool holders are supported on a reference diameter called the gage line. FALCON tool holders are supported on the flange face, which brings remarkable improvement to rigidity. PLBT Tool Holder Provides More Rigid Clamping than the Standard BT Tool Holders. These holders enable the machining operation to achieve Higher Radial Rigidity. PLBT tool holders improve the Tool Life for a long period.

The tooling workpiece is balanced to 2.5G, up to 25000 RPM. The base material used in the manufacturing of PL BT dual contact holder is the Case hardened steel. The tensile strength in the chosen base material of the PL BT consists of core min. 950 N/mm² . The case hardened is converted into HRC 58 ± 2. Case Depth 0.8mm is achieved with Silver finish. The accuracy of 7:24 Taper Angle Class AT 3 is designed to achieve as per DIN 2080
