Syic SYIC-93124 Tool Holder

Syic SYIC-93124 HSK63AXSFC3/4-3.94 Tool Holder is a shrink-fit, HSK63A taper tool holder designed for high-speed CNC milling with through-coolant capability. It is sized for 3/4 in. tooling shanks and features a 3/4 in. bore and a 3.94 in. projection, enabling precise tool reach in tight cavities. The holder is balanced to 25,000 rpm and offers a total indicator runout (TIR) of 0.0001 in., ensuring concentricity at high speeds. It adheres to ANSI, DIN 6499, and ISO standards for HSK63A tooling systems and supports through-coolant delivery to the tooling interface for improved chip evacuation and tool life. This SYIC model (Mfr. 93124) is intended for precision milling applications using carbide end mills and other 3/4 in. shank cutters, providing repeatable tool changes when paired with compatible shrink-fit adapters and heat equipment. Through its shrink-fit design, it delivers rigid clamping with minimal runout, making it suitable for finishing passes, contouring, and high-speed milling where stability and accuracy are critical.
