Parlec DA180-0390 Double Angle Collet DA180 25/64

Product Description

The PARLEC DA180-0390 is a double angle collet in the DA180 series, designed to hold round-shank tooling securely in compatible collet chucks used on milling machines, machining centers, and CNC equipment. It accepts workpieces and tool shanks with a nominal bore size of 25/64 inch (0.3906 decimal inch), with a minimum collet capacity of 0.3750 decimal inch and a maximum of 0.3906 decimal inch. The overall length is 1.639 inches and the overall diameter is 1.025 inches. Machinists and CNC operators install this collet when a close-tolerance, repeatable grip on round tooling is required at the spindle.

This collet is suited for production machining environments where the DA180 collet system is already in use. Typical applications include end mill holding, drill chuck replacement setups, and general-purpose tool clamping on vertical and horizontal machining centers. It is appropriate for both job-shop and high-volume production settings where consistent tool runout and grip force matter across repeated tool changes.

Key Features

• DA180 collet series with double angle design for secure, centered clamping
• Nominal bore size of 25/64 inch with a capacity range of 0.3750 to 0.3906 decimal inch
• Overall length of 1.639 inches for precise spindle seating
• Overall diameter of 1.025 inches compatible with DA180 series chuck bodies
• Compact, precision-ground body supports low tool runout in high-speed applications

Compatibility

Designed as a direct-fit collet for DA180 series collet chucks. Specific chuck model compatibility should be confirmed against the DA180 collet system specifications before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and the control placed in an appropriate safe state before collet or tooling changes. Collets should be inspected for wear, damage, or contamination before seating in the chuck body, as debris on the collet taper can affect runout and clamping force. Tighten the collet nut using the manufacturer-recommended spanner wrench for the DA180 system; do not use pipe wrenches or improvised tools that can damage the nut or chuck body.
