Eliminate harmonic chatter and maximize surface finish quality during long-overhang internal machining with industrial-grade Boring Bar Stabilisers (anti-vibration dampening sleeves). Specially engineered with a heavy-duty cylindrical shank and slotted clamping sleeve, these specialized toolholders absorb high-frequency cutting vibrations associated with deep-hole boring operations. Equipped with dual high-tensile side clamping screws, they deliver uniform 360-degree radial clamping force along the boring bar shank, preserving insert cutting edges and enabling higher feeds and speeds in deep internal turning sequences.
