Micro 100 ER16S-1 ER16 Collet Set 10 Piece Steel

Product Description

The MICRO 100 ER16S-1 is a 10-piece ER16 collet set designed for use in CNC machining centers, milling machines, and high-speed spindle applications. Each collet in the set is manufactured from steel and holds a Total Indicator Runout (TIR) of 0.0004 inches, making this set appropriate for precision work where concentricity directly affects surface finish and tool life. The set covers a clamping range from 0.054 inches to 0.375 inches, giving machinists coverage across a broad range of shank diameters without changing collet chucks. At 1.5 pounds, the set is compact and easily stored at the machine.

This collet set is suited for professional machine shops, tool rooms, and production environments running ER16-compatible spindles. It supports a wide range of cutting tools including end mills, drills, reamers, and taps within the covered diameter range. The ER16 series is a widely adopted standard in both light-duty CNC work and manual milling setups, making this set a practical addition to any tooling inventory where consistent, repeatable tool holding is required.

Key Features

• ER16 series collets compatible with standard ER16 collet chucks
• TIR of 0.0004 inches for precision tool holding and concentricity
• Clamping range from 0.054 inches to 0.375 inches across 10 collets
• Steel construction for durability under repeated clamping cycles
• 10-piece set provides broad diameter coverage in a single purchase

Compatibility

Designed for use with standard ER16 collet chucks and ER16-compatible spindle tooling systems.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians familiar with ER-style collet systems. Before changing collets, ensure the spindle is fully stopped and the machine is in a safe, locked-out state per shop safety procedures. Use the appropriate ER16 collet nut wrench and chuck wrench to seat and torque the collet nut; do not use makeshift tools that can damage the collet nut or chuck threads. Inspect collets regularly for wear, dings, or corrosion that could compromise TIR performance.
