Techniks SYIC-22239-N CAT40XER20-6 Collet Chuck Tool Holder

The Techniks SYIC-22239-N CAT40×ER20-6 Collet Chuck Tool Holder is a high-precision tool holder that securely grips ER20 collets for milling, drilling, reaming, and tapping with extended reach in CAT40 CNC centers. Built for CAT40 (V-Flange) spindles, it features a 6 in (152.4 mm) projection length, 1.75 in (44.5 mm) body diameter, 2.50 in (63.5 mm) nose diameter, 2.69 in (68.3 mm) taper length, and an overall length of 8.68 in (220.5 mm) with a collet range of 0.5–14 mm (0.019–0.550 in). Made from hardened 8620 alloy steel and balanced to G2.5 at 25,000 RPM, the holder delivers a maximum runout of 0.0001 in (0.0025 mm) TIR and supports through-spindle coolant as well as CoolFLEX AD+B flange coolant systems. The SYIC-22239-N uses a Techniks PowerCOAT Nut (included) and is designed for precise tool holding in milling, drilling, reaming, and tapping, commonly used in aerospace, automotive, mold and die, and medical device manufacturing environments where rigid grip and minimal runout are essential.
