Techniks/SYIC BT40 shrink-fit tool holder designed for cutting tools with a precise 1/2-inch shank. Part number 39114 provides a 90mm—or 3.54-inch—projection for high-speed CNC milling and extended-reach applications.
Shrink-fit clamping provides rigid, concentric tool retention without a conventional collet or side-lock screw. The holder is balanced to G2.5 at 25,000 RPM and rated for maximum runout of 0.0001 inch.
An unidentified used cutting tool and BT40 retention knob are installed and included as pictured.
