Parlec DA300-0250 Double Angle Collet DA300 1/4 Inch

Product Description

The PARLEC DA300-0250 is a double angle collet in the DA300 series, designed for use in CNC machining centers, milling machines, and toolholding systems that accept DA300-style collet chucks. It clamps round shank tooling with a nominal capacity of 1/4 inch, spanning a minimum capacity of 0.2344 inches to a maximum of 0.2500 inches. The overall length is 1.0 inches and the overall diameter measures 0.3750 inches. Machinists and toolroom technicians rely on this collet to hold end mills, drills, reamers, and similar round-shank cutting tools with repeatable concentricity during metal removal operations.

This collet suits production and job-shop environments where DA300 collet chucks are in service. It is appropriate for light to medium duty milling, drilling, and reaming on vertical or horizontal machining centers. The 1/4 inch capacity makes it a common choice for holding small-diameter end mills and drill blanks in general-purpose metalworking and tool-and-die applications. Installation is performed by qualified machinists or toolroom personnel during tooling setup or changeover.

Key Features

Compatibility

Designed for use in DA300-series collet chucks that accept the double angle collet format. Confirm chuck series and collet seat geometry before installation.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing collets. Inspect the collet bore and chuck seat for chips or wear before seating the collet. Do not exceed the stated maximum tool shank diameter of 0.2500 inches, as oversized tooling can damage the collet or reduce clamping integrity.
