Parlec 5UMER32-SI014 ER32 Collet Set 14 Piece

Product Description

The PARLEC 5UMER32-SI014 is a 14-piece ER32 collet set designed for precision toolholding in CNC machining centers, milling machines, and drilling applications. The set covers a capacity range from 1/8 inch to 13/16 inch, giving machinists and toolroom technicians a broad selection of sizes in a single kit. Each collet in the set holds a Total Indicator Runout (TIR) of 0.0002 inches, supporting tight-tolerance work where concentricity directly affects surface finish and tool life. The ER collet system is one of the most widely adopted standards in production machining, and this set is built to that spec.

This collet set is suited for use in production and job-shop environments running ER32-compatible toolholders. Typical applications include end milling, reaming, drilling, and tapping operations on CNC vertical machining centers and manual knee mills. The 14-piece assortment spans the most commonly demanded shank sizes in the ER32 range, making it a practical bench stock for shops that run mixed tooling. Machinists, toolroom operators, and CNC setup technicians are the primary users of this type of set.

Key Features

• 14-piece set covering 1/8 inch through 13/16 inch capacity in the ER32 collet series
• 0.0002 inch TIR for high-concentricity toolholding in precision machining
• ER32 collet system compatibility, one of the most widely standardized toolholding formats in CNC machining
• Broad size assortment eliminates the need to source individual collets for common shank sizes
• Set weight of 15 pounds reflects solid construction throughout

Compatibility

Designed for use with ER32-compatible collet chucks and toolholders. Fits any machine spindle or holder built to the ER32 collet standard.

Installation Notes

Collet sets of this type are installed and serviced by machinists or CNC setup technicians. Before changing collets, ensure the machine spindle is fully stopped and the control is in a safe state. Collets should be seated properly in the holder before the retention nut is tightened using the appropriate ER32 spanner wrench. Inspect each collet for burrs, chips, or deformation before use, as contamination directly affects runout and can damage tooling.
