Milling arbors for screw-in cutters SK 50 - M8 - 169 - LB150

Milling arbors for screw-in cutters SK 50 - M8 - 169 - LB150Application: For mounting screw in cutters with thread. 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

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

For mounting straight-shank tools in collet chucks DIN 6391

To use for high speed cutting and high precision milling

d = 40/d = 60: For large diameter face mill cutters with four additional threaded holes according to DIN 2079

With built-in tightening bolt

low warpage hardened

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

lockable in different positions

LSCX = Clamping depth

critical factors for successful deep face grooving operations

For internal machining with boring bars
