Parlec ER32-0748 ER32 Collet 0.748 Inch Bore

Product Description

The PARLEC ER32-0748 is an ER32 series collet with a 0.748-inch bore capacity and an overall length of 1.574 inches. Designed for use in ER32-compatible collet chucks, it grips round workpieces and cutting tools during milling, drilling, and turning operations. The collet provides concentric clamping force across the bore range, making it a standard tool-holding component for CNC machining centers, manual mills, and lathes. Machinists, tool crib technicians, and shop setups rely on ER-series collets for repeatable, secure tool holding in production and job-shop environments.

This collet is suited for machine shops and manufacturing facilities running ER32 toolholding systems. It accommodates a minimum collet capacity of 0.7087 inches (18.0 mm), making it appropriate for near-maximum bore applications in the ER32 size range. Typical applications include holding end mills, drill bits, reamers, and other round-shank cutting tools where accurate concentricity and consistent clamping are required.

Key Features

• ER32 collet series for compatibility with standard ER32 chucks and tool holders
• 0.748-inch (19.00 mm) bore size for near-maximum ER32 capacity tool holding
• Minimum collet capacity of 0.7087 inches (18.0 mm) for the usable clamping range
• Overall length of 1.574 inches for correct seating in ER32 collet chucks
• Consistent clamping geometry supports repeatable tool runout in CNC and manual setups

Compatibility

Designed as a direct-fit replacement or additional collet for standard ER32 collet chucks and ER32-compatible toolholding systems.

Installation Notes

Installation is performed by machinists or toolroom technicians. Always ensure the spindle or chuck is fully stopped and the machine is in a safe, de-energized state before changing collets. Clean the collet taper and chuck bore before seating to prevent runout caused by chips or debris. Use the appropriate ER32 collet nut and spanner wrench to tighten to the chuck manufacturer's specified procedure - do not overtighten by impact methods.
