Accupro 784505 DA100 Collet Set 29 Pc 1/8 to 9/16 in

Product Description

The ACCUPRO 784505 is a 29-piece DA100 series double angle collet set covering a clamping range of 1/8 inch (0.1250 inch) to 9/16 inch (0.5625 inch) in 1/64-inch increments. Designed for DA100-style toolholders, this set provides a full range of collets for holding end mills, drills, reamers, and other round-shank cutting tools on CNC machining centers and manual mills. Total indicated runout (TIR) is rated at 0.02 mm, delivering the precision required for finish machining and close-tolerance work. The complete 29-piece assortment eliminates the need to source individual collets for a DA100 spindle setup.

This collet set is suited for machine shops, toolrooms, and production environments running DA100-compatible spindles. It covers the most common shank sizes used in general machining, from small-diameter tooling at 1/8 inch up through 9/16 inch for heavier-duty cutters. Machinists, CNC operators, and tool crib personnel who need a ready-to-use collet assortment for a DA100 toolholder system will find this set a practical one-purchase solution.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Power down and lock out the machine spindle before changing collets. Ensure the collet bore, toolholder taper, and collet nut are clean and free of chips or coolant residue before seating the collet. Torque the collet nut to the toolholder manufacturer's specification using the appropriate spanner wrench — do not use a hammer or improvised tools to seat or remove collets.
