Techniks SYIC-22243-N Tool Holder CAT40XER25-2.76 G:2.5 18000Rpm

High-precision CAT40 ER25 collet chuck tool holder designed for CNC milling, drilling, reaming, and tapping, delivering 0.0001 in TIR for exceptional concentricity and rigidity. The Techniks SYIC-22243-N supports ER25 collets with a 2.76 in (70.1 mm) projection and a 2.63 in (66.9 mm) gage length, a workpiece-side body diameter of 1.654 in (42 mm), a 1.65 in (41.9 mm) lock nut diameter, an overall diameter of 2.50 in (63.5 mm), and an overall length of 5.44 in (138.2 mm); capacity range 0.039–0.750 in (1–19.1 mm). Made from hardened 8620 alloy steel, it is balanced to G2.5 at 25,000 RPM and is capable of 18,000 RPM operation, with through-spindle coolant compatibility. The ER25 slotted PowerCOAT nut is included for secure clamping, making it suitable for high-speed precision tool holding in CAT40 vertical and horizontal machining centers, CNC milling machines, and OEM metalworking equipment. Common applications span aerospace, automotive, mold and die, medical device manufacturing, and general precision metalworking where minimal runout and superior rigidity are essential.
