Accupro 784511 DA180 Collet Set 41 Pc 1/8 to 3/4 in

Product Description

The ACCUPRO 784511 is a 41-piece DA180 series double angle collet set covering a clamping range of 1/8 inch to 3/4 inch in 1/64-inch increments. Each collet in the set is machined to a total indicator runout (TIR) of 0.02 mm, delivering the concentricity required for precision milling, drilling, and reaming operations. The DA180 double angle design provides secure tool holding under both light finishing passes and heavier cutting loads. This set is installed and used by machinists and toolroom technicians working on CNC machining centers and manual milling equipment where consistent runout control is essential to part quality.

This collet set is suited for production and job-shop environments where a wide range of tooling diameters must be accommodated from a single collet system. The 41-piece assortment covers fractional inch sizes from 1/8 inch through 3/4 inch, including intermediate 1/64-inch steps such as 11/64, 13/64, 15/64, and 17/64 inch, giving technicians the flexibility to run a broad selection of shank diameters without purchasing individual collets separately. Applications include vertical and horizontal milling centers equipped with DA180-compatible spindles.

Key Features

• 41-piece set spans 1/8 inch to 3/4 inch in 1/64-inch increments for full fractional coverage

Compatibility

Designed for use with DA180 series double angle collet chucks and toolholders that accept the DA180 collet system.

Installation Notes

DA180 collets are installed by qualified machinists or toolroom personnel. Before changing collets, power down the spindle completely and confirm the machine is in an e-stop or lockout-tagout state per OSHA 29 CFR 1910.147. Seat the collet fully into the chuck before threading on the nut, and inspect each collet for chips or damage that could affect runout before use. Do not exceed the collet manufacturer's recommended RPM or clamping torque range for the collet series in use.
