Tecnara 400-302-2 End Mill Tool Holder

The Tecnara 400-302-2 End Mill Tool Holder delivers rigid, precise retention for 5/16 in. (7.94 mm) shank end mills on CAT50 spindle interfaces, enabling accurate milling, drilling, slotting, and contouring on CNC centers. This solid holder uses a CAT50 taper, a 2 in. projection length, and a hardened alloy steel body secured by a side-Lock set screw, delivering high concentricity, reduced runout, and reliable tool clamping under production workloads. Compatible with vertical and horizontal machining centers and other CNC milling machines that use CAT50 interfaces, it functions as an OEM replacement component for production machining, tooling replacement, machine setup, and preventive maintenance in aerospace, automotive, mold and die, and general machining environments. Common replacements include Tecnara 400-302-4, Tecnara 400-302-6, and Techniks CAT50. In high-precision production environments, this holder helps maintain consistent machining performance by keeping end mills securely aligned throughout demanding milling, drilling, and contouring operations.
