Lyndex 500-067 5C 1-3/64 in Round Collet

This is a new Lyndex 5C round collet, part number 500-067, sized to grip 1-3/64 inch (approximately 1.046875 in) round stock, confirmed by both the embossed face marking and the original box label. The 5C collet system features a 5/8-16 UN external nose thread, a 10-degree included taper angle, and a maximum workpiece capacity of 1-1/16 in for standard steel collets — this 1-3/64 size sits just above that standard range, placing it in the large-bore segment of the 5C series designed for larger-diameter bar stock and workholding applications. Constructed from hardened alloy tool steel with a ground bore, 5C collets of this type deliver runout accuracy typically within 0.0005 in TIR and are compatible with 5C spindle-nose lathes, collet chucks, indexing fixtures, and collet closers from manufacturers such as Hardinge, Royal, and equivalent 5C-standard equipment. Lyndex (now Lyndex-Nikken) is a recognized U.S. manufacturer of precision workholding and toolholding products; this collet ships new in its original factory box.
