Lyndex-nikken 300-035 Round Collet 35/64 Inch

Product Description

The LYNDEX-NIKKEN 300-035 is a round collet designed for precision workholding in CNC machining and manual machine tool applications. It accepts a 35/64-inch bore diameter and features a 1.988-20 external thread for secure mounting in compatible collet chucks and closers. The overall length measures 3-3/4 inches. With a total indicator runout (TIR) of 0.0011 inches, this collet delivers the concentricity accuracy required for finish turning, milling, and grinding operations where part tolerance is critical. Machinists, toolroom technicians, and CNC setup personnel are the primary installers and users of this component.

This collet is suited for use in production and toolroom environments where repeatable workholding accuracy is essential. It is appropriate for both light and moderate-duty cutting operations on lathes, mills, and grinding machines equipped with a 1.988-20 threaded collet seat. The 35/64-inch capacity makes it a practical choice for holding bar stock, shafts, or tooling shanks at that specific diameter. Shops running close-tolerance work will find the 0.0011-inch TIR specification relevant to maintaining consistent part geometry across production runs.

Key Features

• 35/64-inch bore capacity for precise round workholding
• 1.988-20 external thread for secure chuck or closer engagement
• 0.0011-inch TIR for high concentricity accuracy
• 3-3/4-inch overall length suits standard collet chuck depths
• Round collet style compatible with a wide range of machine tool spindles

Compatibility

Designed as an OEM-style round collet for machine tool spindles and collet chucks accepting a 1.988-20 external thread with a 35/64-inch bore capacity.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The machine spindle must be fully stopped and all power isolated before collet installation or removal. Threads and collet seats should be cleaned and inspected for damage or debris prior to seating the collet. Do not exceed the rated bore capacity, as oversize workpieces will damage the collet and reduce concentricity.
