Parlec DA100-0390 Double Angle Collet DA100 25/64 in

Product Description

The PARLEC DA100-0390 is a Double Angle (DA) style collet in the DA100 series, designed to hold round-shank cutting tools and workholding fixtures in compatible DA collet chucks. With a nominal bore size of 25/64 inch (0.3906 decimal inch) and an overall length of 1.437 inches, this collet delivers firm, concentric clamping across its full capacity range. Overall outside diameter measures 0.769 inches. Machinists and CNC setup technicians install DA collets during tool changes on milling, drilling, and tapping operations where the double-angle design provides secure, repeatable grip on tooling shanks.

This collet is suited for use in light-duty to medium-duty machining applications including drilling, reaming, and tapping in manual or CNC machine tool environments. The DA100 series fits DA100-designated collet chucks and tool holders. It accommodates tool shanks ranging from 0.375 inches minimum to 0.3906 inches maximum collet capacity, making it appropriate for 25/64 inch shank tooling commonly encountered in general machine shop work.

Key Features

• Double Angle collet design provides secure, concentric clamping for round-shank cutting tools

Compatibility

Designed for use with DA100 series collet chucks and tool holders that accept Double Angle collets. Verify chuck series designation before installation to confirm fitment.

Installation Notes

DA collets are installed and removed by qualified machinists or CNC toolroom technicians. Always power down and lock out the machine spindle before changing collets. Inspect the collet bore and the chuck taper for chips, burrs, or wear before seating the collet. Do not use a collet outside its rated capacity range, as under- or over-clamping a tool shank can result in runout or tool pullout during cutting.
