Accupro 784882 ER16 Collet 0.219 Inch

Product Description

The ACCUPRO 784882 is an ER16 series collet designed for use in CNC machining centers, manual mills, and other spindle tooling applications that accept the ER16 collet standard. With a collet size of 0.219 inches and a minimum collet capacity of 0.188 inches, this collet provides a secure clamping range suitable for holding straight-shank tooling within that range. Weighing 0.05 pounds, the collet is compact and fits within the standard ER16 nut-and-chuck system. Machinists and tool-room technicians rely on ER-series collets for their repeatable runout performance and broad compatibility across ER16-compatible tool holders.

This collet is suited for light-duty to medium-duty cutting operations in ferrous and non-ferrous materials. It installs into any ER16-compatible collet chuck or collet block and is appropriate for use in production shops, job shops, and maintenance machining environments. The 0.219-inch decimal size accommodates specific shank diameters within its clamping range, making it a targeted replacement or addition to an existing ER16 collet set.

Installation Notes

Installation should be performed by a qualified machinist or tool-room technician familiar with ER collet systems. Before inserting or removing a collet, ensure the spindle is fully de-energized and at a complete stop. Seat the collet into the collet nut before threading the assembly onto the chuck body to prevent collet damage and ensure proper clamping force. Inspect the collet bore and chuck taper for debris or damage before each use to maintain runout accuracy.
