Micro 100 ER16-093 ER16 Collet 3/32 Inch

Product Description

The MICRO 100 ER16-093 is an ER16-series collet designed to hold cutting tools and workholding shanks with a 3/32 inch (0.0937 inch) bore diameter. It delivers a total indicator runout (TIR) of 0.0004 inches, providing the concentricity required for precise milling, drilling, and reaming operations. The collet seats into a compatible ER16 collet chuck and is tightened with a standard ER nut to clamp the tool shank securely. Machinists and toolroom technicians install this collet in CNC machining centers, manual milling machines, and drilling setups where accurate tool holding at small diameters is critical.

This collet is suited for light-duty and precision machining applications using tools with 3/32 inch shanks. Typical uses include small-diameter end mills, drill bits, reamers, and engraving cutters in both production and prototype environments. The ER16 series is a widely used standard in the machining industry, making this collet compatible with ER16 chucks across a broad range of machine tool brands and spindle configurations. It is appropriate for both shop production work and toolroom applications where runout control is a priority.

Key Features

• 3/32 inch (0.0937 inch) bore for small-shank cutting tools
• TIR of 0.0004 inches for high concentricity and accurate tool positioning
• ER16 series standard - fits any ER16-compatible collet chuck
• No through-coolant configuration - suited for dry and flood coolant setups that direct coolant externally
• Lightweight at 0.1 pounds, minimizing added mass on the spindle

Compatibility

Designed as a standard ER16-series collet for use with any ER16 collet chuck that accepts the ER16 collet form factor.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine spindle fully stopped and the machine powered down or in a safe locked-out state. The collet should be snapped into the ER collet nut before threading the nut onto the chuck body, then torqued with a properly sized ER collet wrench to the chuck manufacturer's specification. Inspect the collet seating surfaces and the chuck bore for chips or contamination before clamping. Do not use a collet that shows visible wear, cracking, or deformation, as this will compromise runout and tool security.
