Accupro 784507 DA180 Collet Set 9 Pc 1/4 to 3/4 Inch

Product Description

The ACCUPRO 784507 is a 9-piece DA180 double angle collet set covering a capacity range of 1/4 inch to 3/4 inch in 1/16-inch increments. Designed for use in DA180-series toolholders, this set gives machining professionals a complete range of collet sizes in a single purchase. The set includes collets sized at 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, and 3/4 inch. Total indicated runout (TIR) is rated at 0.02 mm, supporting accurate workholding across the full capacity range. The set weighs 1.8 pounds and is suited for CNC machining centers, milling machines, and similar machine tool applications.

This collet set is intended for machine shops and production environments where DA180-series toolholding is standard. It suits both manual and CNC milling setups that require consistent, repeatable workholding across a broad range of shank diameters. The 1/16-inch size increments make it practical for shops working with a variety of tool shank sizes without maintaining a large individual collet inventory. Machinists, tool and die professionals, and CNC operators are the primary installers and users of this type of set.

Installation Notes

Collet installation and removal should be performed with the machine spindle fully stopped and energy isolated per lockout/tagout procedures. Use the appropriate collet wrench and toolholder nut for the DA180 series — do not substitute tools that may damage the collet taper or nut threads. Inspect collet bores and seating surfaces for chips or damage before installation. Proper seating of the collet in the holder is required to achieve rated TIR performance.
