Accupro 587639 ER8 Collet 2.00mm 0.0787 Inch

Product Description

The ACCUPRO 587639 is an ER8 series collet designed for precision toolholding in CNC machining and manual milling applications. Sized at 2.00mm (0.0787 inches), it delivers a Total Indicated Runout (TIR) of 0.0100mm, making it suitable for high-accuracy work where concentricity matters. The overall length is 13.0mm and the overall diameter is 8.5mm. This collet is installed by machinists and toolroom technicians into compatible ER8 collet chucks on milling machines, lathes, routers, and engraving spindles.

This collet is suited for light-duty precision machining tasks in both production and job-shop environments. The 2.00mm bore accommodates small-diameter cutting tools, drill bits, and engraving bits. A minimum collet capacity of 1.5mm (0.059 inches) allows for slight variation in tool shank diameter within the clamping range. It is packaged individually and is a direct fit wherever ER8 collet chucks are specified.

Key Features

• ER8 collet series for use with standard ER8 collet chucks
• 2.00mm (0.0787 inch) nominal collet size for small-diameter tooling
• 0.0100mm TIR for high concentricity and precise tool positioning
• 13.0mm overall length with 8.5mm overall diameter
• Minimum collet capacity of 1.5mm (0.059 inches) for flexible clamping range

Compatibility

Designed for use with ER8 series collet chucks as an OEM-style precision toolholding collet. Specific chuck compatibility depends on the machine spindle and chuck manufacturer.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing the collet. Seat the collet fully into the ER8 collet nut before threading onto the chuck body, and tighten using the appropriate ER collet wrench to the chuck manufacturer specifications. Do not overtighten or use impact tools on collet nuts.
