High Performance Milling Chuck BT 50-20-95 JIS B 6339 (MAS-BT) HKS-system in wooden boxApplication: For mounting straight shank tools. All holders are made of forged steel Specific, low warpage hardened Surface hardened HRC 58~60 Hardening depth 0,8mm~0,9mm Taper angle tolerance < AT 3 according to DIN 2080 Surface roughness Ra < 0,4 m Tensile strength in the core of min. 800 N mm after DIN All functional surfaces fine machined

For mounting straight-shank tools in collets

With wrench

For internal machining with boring bars

For retaining screw DIN 6367

With drivers

Mainly for external machining

without a tool

length adjustment range

improves thread quality

The tapered tool holder is thus optimally

For mounting straight-shank tools

Coolant pressure up to max
