Value Collection 204-1602 ER16 Collet 0.0312 Inch

Product Description

The VALUE COLLECTION 204-1602 is an ER16-series collet designed to hold cutting tools and workpieces with a nominal grip diameter of 0.0312 inches (1/32 inch). It delivers a total indicated runout (TIR) of 0.0005 inches, making it well suited for precision machining operations where concentricity is critical. ER collets of this series are a standard workholding solution in CNC milling, drilling, and high-speed spindle applications. Installation and use are performed by machinists and toolroom technicians working with ER16-compatible collet chucks and spindle holders.

This collet is used in light-duty machining centers, CNC routers, and manual milling machines equipped with ER16 collet chucks. The 0.0312-inch bore accommodates small-diameter end mills, drills, reamers, and similar tooling commonly used in precision part production. It is a practical single-piece replacement or addition to an existing ER16 toolholding setup in both job-shop and production environments.

Key Features

• ER16 collet series for use with standard ER16-compatible chucks and holders
• 0.0312-inch (1/32 inch) bore diameter for small-diameter tooling
• 0.0005-inch TIR for repeatable, high-precision tool runout control
• Single-piece package quantity suitable for individual tooling builds or replacement
• Lightweight at 0.09 pounds for minimal spindle load contribution

Compatibility

Designed as an OEM-style replacement or supplemental collet for use with ER16-compatible collet chucks and toolholders in CNC and manual machining applications.

Installation Notes

Installation is performed by machinists or toolroom technicians. Before seating the collet, ensure the spindle and chuck are fully powered down and locked out per facility lockout/tagout procedures. Insert the collet into the ER16 chuck nut before threading onto the holder, and tighten to the chuck manufacturer's specified torque range using an appropriate ER collet wrench. Inspect the collet bore and seating surfaces for debris or damage before each use to maintain TIR performance.
