Used in CAT50 machining centers where the spindle does not provide internal coolant delivery, the Collis 73893 coolant-induced tool holder mounts via a CAT50 (V-flange) outside taper and accepts tooling through a VF50 inside taper with a 1-1/2-inch bore diameter. The holder body incorporates an external coolant connection fitting that delivers coolant through the assembly to the cutting tool, enabling through-coolant performance without modification to the machine spindle. Published specifications list a 5.75-inch projection and a 9.75-inch overall length. This configuration is designed for use with Weldon shank tools and annular cutters in applications requiring coolant delivery at the cutting zone. Collis Toolholder Corporation has manufactured precision toolholding products in Clinton, Iowa since 1912, and the 73893 is part of their coolant-induced holder series. The part number is partially visible on the body of the holder; identification as 73893 is based on the CAT50 taper interface confirmed by the operator and cross-referenced against the Collis published catalog, which lists 73893 as the sole CAT50 model in this coolant-induced holder series. Manual review of the full stamped part number is recommended before publishing.
