SYIC extended-reach BT40 shrink-fit tool holder designed for 1/4-inch shank cutting tools. The slim 6-inch projection provides access to deep pockets, molds, cavities, and other difficult-to-reach machining areas.
Shrink-fit technology provides rigid, uniform tool clamping without a collet or set screw. The holder is balanced to G2.5 at 25,000 RPM for high-speed CNC machining.
An unidentified carbide ball-nose-style end mill and BT40 retention knob are installed and included as pictured.
