Parlec 5UMER32-0812 ER32 Collet 0.8125 Inches

Product Description

The PARLEC 5UMER32-0812 is an ER32 series collet designed for use in CNC machining centers, milling machines, and precision drilling applications. It accepts a collet size of 0.8125 inches (13/16 inch) with a minimum collet capacity of 0.773 inches, making it suitable for a range of tooling diameters within that span. The collet holds a total indicated runout (TIR) of 0.0002 inches, supporting tight-tolerance work where tool concentricity directly affects surface finish and part accuracy. The overall length is 1.574 inches. Machinists and toolroom technicians working in production or job-shop environments install this collet as part of an ER32 toolholder assembly.

This ER32 collet is used in shops running vertical or horizontal machining centers, lathes with live tooling, and drill-tap machines that use the ER32 standard. It is well-suited for high-speed spindle applications where low runout is required to maintain dimensional consistency across production runs. The 0.8125-inch size accommodates end mills, drills, reamers, and taps within its capacity range. It is appropriate for both ferrous and non-ferrous cutting operations in general manufacturing environments.

Key Features

• ER32 collet series for broad compatibility with ER32-standard toolholders
• 0.8125 inches (13/16 inch) collet size with a minimum capacity of 0.773 inches
• 0.0002 inches TIR for high-precision, low-runout tool clamping
• 1.574 inches overall length fits standard ER32 collet nuts and chucks
• Lightweight at 0.38 pounds, minimizing added spindle load

Compatibility

Designed as an OEM-style replacement or standard tooling component for machines equipped with ER32-standard collet chucks and toolholders.

Installation Notes

ER32 collets are installed by machining technicians and toolroom professionals. Before changing collets, power down the machine and follow lockout/tagout procedures per applicable shop safety standards. Seat the collet fully into the ER32 collet nut before threading onto the toolholder to prevent damage to the collet taper. Inspect the collet bore and toolholder taper for chips or contamination before assembly, as debris will directly degrade TIR performance.
