Lyndex-nikken 800-006 R8 Collet 3/32 Inch Steel

Product Description

The LYNDEX-NIKKEN 800-006 is a steel R8 collet designed for use in Bridgeport-style and compatible vertical milling machines that accept the R8 spindle taper. This collet holds tooling with a 3/32 inch shank diameter and features a 7/16-20 drawbar thread for secure clamping. It is manufactured from steel for durability under repeated clamping cycles and machining loads. Total indicator runout (TIR) is rated at 0.0007 inch, supporting accurate tool positioning for precision milling work. Machinists and toolroom technicians are the primary users of this type of collet in manual and CNC knee-mill applications.

R8 collets are standard toolholding components in manual vertical mills found in job shops, maintenance facilities, and light manufacturing environments. This collet is suited for holding small-diameter end mills, drills, or other round-shank cutting tools in the 3/32 inch size. The R8 system is a friction-retained, self-releasing taper that uses a drawbar to lock the collet in the spindle, making tool changes straightforward for experienced machine operators.

Key Features

• 3/32 inch bore diameter for small-shank tooling
• R8 taper profile for Bridgeport-style vertical mill spindles
• 7/16-20 drawbar thread for positive spindle retention
• 0.0007 inch TIR for consistent tool concentricity
• Steel construction for long service life under repeated clamping

Compatibility

Designed as an OEM-style replacement or standard toolholding component for vertical milling machines equipped with an R8 spindle taper and a 7/16-20 drawbar thread.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before changing collets, power down the machine and bring the spindle to a full stop. Insert the collet into the spindle taper and engage the drawbar by hand before tightening with the appropriate wrench - do not overtighten, as this can gall the taper or damage the collet. Follow the machine manufacturer's drawbar torque guidelines and inspect the collet bore and taper for chips or wear before each use.
