Accupro 784803 ER16 Collet 0.153 in Capacity

Product Description

The ACCUPRO 784803 is an ER16 series collet designed for use in CNC machining centers, milling machines, and other rotating spindle equipment that accept ER16 toolholders. With a decimal inch collet size of 0.153 inches and a minimum collet capacity of 0.141 inches, this collet provides secure clamping across that range. The overall length measures 1.063 inches (27 millimeters), keeping the tool assembly compact within the spindle. Machinists and toolroom technicians install this collet when setting up precision cutting or drilling operations that require consistent tool runout and reliable grip force.

This collet is suited for light to medium-duty machining applications in job shops, production facilities, and toolroom environments. The ER16 series is one of the most widely used collet standards in CNC routing, engraving, and small-diameter milling work. It fits any ER16-compatible collet chuck or toolholder, making it a straightforward replacement or addition to an existing tooling inventory. The 0.153-inch size is commonly used when running fractional or wire-gauge cutting tools at that diameter.

Installation Notes

ER16 collets are installed by machinists or toolroom technicians using an ER16 collet nut and compatible chuck body. Always ensure the spindle is powered down and locked out before inserting or removing collets. Seat the collet fully into the collet nut before threading onto the chuck to avoid cross-threading or uneven clamping. Inspect the collet bore and chuck taper for chips or debris before assembly to maintain runout accuracy.
