Note: l1 = max. clamping depth l2 = max. length adjustment range Delivery: With wrench 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

Toolholders suitable for induction-

safe clamping of parallel raw and sawn parts

With built-in tightening bolt All holders are made of forged steel

With securing screws and Tee-nuts

so the system is suitable for through-coolant feed

DIN 1835 form A+B+E and DIN 6535 form HB+HE

Integrated pull-down mechanism

Adaptive interface machine direction (ADINTMS): BMT non-driven turret interface -size BT65A

which can cause high frictional forces on the thread flanks
