Accupro 586294 DA300 Double Angle Collet 9/64 Inch

Product Description

The ACCUPRO 586294 is a double angle collet in the DA300 series, designed for use in DA-style collet chucks on milling machines, machining centers, and CNC drilling equipment. This collet accepts a 9/64 inch (0.14060 inch) tool shank and delivers the clamping rigidity required for precision cutting and drilling operations. With an overall length of 1 inch and an outer diameter of 0.3750 inch, this collet fits the compact DA300 collet system. Machinists, toolroom technicians, and CNC operators install this type of collet when setting up end mills, drills, or reamers that match the collet bore size.

This collet is suited for light-duty to medium-duty machining applications where DA300-series toolholders are already in use. Typical installations include vertical machining centers, knee mills, and benchtop drill-mill machines in job shops, production facilities, and maintenance shops. It is appropriate for both ferrous and non-ferrous workpiece materials when the tool shank diameter matches the 9/64 inch bore specification.

Key Features

Compatibility

Designed as an OEM-style replacement or standard collet for DA300-series collet chucks accepting a 9/64 inch tool shank diameter.

Installation Notes

Installation is performed by machinists or toolroom technicians during toolholder setup. Always ensure the spindle is fully stopped and the machine is powered down before changing collets. Clean the collet taper, chuck bore, and clamping nut threads before assembly to ensure proper seating and runout performance. Do not exceed the chuck manufacturer's recommended torque range for the clamping nut, and inspect the collet for wear or cracking before each use.
