End mill holder Weldon with cooling channels SK 50 - 18 - 130Application: For mounting straight shank tools with lateral flat according to DIN 1835 form B (Weldon). Delivery: With clamping screw and O ring 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

High holding forces: increase by a factor of 3 to 5 compared to standard jaws

- display of absolute measuring value or percentage clamping force in relation to reference value

800 N/mm² after DIN

Mainly for external machining

For the coolant supply through the centre of HSK toolholders

With clamping screw and O-ring

For face machining

cross head retaining screw and cylinder head retaining screw for cutters with central coolant

Integrated pull-down mechanism

no adhesion occurs and the tool

A possible increase of axial force during the tapping process is reduced to a minimum

Advantage:
