Parlec DA100-0250 Double Angle Collet DA100 1/4 Inch

Product Description

The PARLEC DA100-0250 is a Double Angle collet in the DA100 series, designed to hold cutting tools and workpieces with a nominal shank diameter of 1/4 inch (0.2500 decimal inch). The collet provides a clamping range of 0.2344 to 0.2500 decimal inches, with an overall length of 1.437 inches and an overall diameter of 0.769 inches. Double Angle collets use a dual-taper contact geometry that delivers high gripping force and accurate tool concentricity, making them a reliable choice for milling, drilling, and tapping operations in CNC and manual machining environments. Machinists and toolroom technicians are the primary installers.

This collet is suited for use in DA100-style collet chucks mounted on CNC machining centers, knee mills, drill presses, and similar machine tool spindles. It is appropriate for light to medium material-removal operations where repeatable tool runout and secure clamping are required. The 1/4 inch capacity makes it a common fit for end mills, drill bits, and taps of that shank size in both production and job-shop settings.

Compatibility

Designed as a direct-fit collet for DA100-series collet chuck bodies requiring a 1/4 inch tool-holding capacity.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before inserting or removing a collet, ensure the machine spindle is fully stopped and locked out per the facility lockout/tagout procedure. Seat the collet fully into the chuck body before threading on the clamping nut, and torque the nut using the appropriate spanner wrench to manufacturer specification. Inspect collet bore and taper surfaces for chips or wear before each use, as contamination or damage will degrade clamping accuracy and increase tool runout.
