Accupro 587666 ER11 Collet 0.196 Inch 5.00mm

Product Description

The ACCUPRO 587666 is an ER11 series collet designed for use in CNC machining centers, milling machines, routers, and high-speed spindles that accept the ER11 collet system. It holds workpieces and cutting tools with a collet size of 0.196 inches (5.00mm) and a minimum collet capacity of 0.177 inches (4.5mm). The total indicated runout (TIR) is 0.02mm, providing the concentricity required for precision cutting operations. This collet is a standard component installed by machinists and toolroom technicians during tooling setup and changeovers.

The 587666 is suited for light-duty CNC routing, engraving, drilling, and milling applications where the ER11 collet standard is specified. The ER11 system is common in compact spindle units and benchtop CNC machines used in production and prototype environments. It accepts shank tooling in the 4.5mm to 5.00mm range, making it appropriate for small-diameter end mills, drill bits, and engraving tools. One collet is included per package.

Key Features

• ER11 collet series for compatibility with ER11 tool holders and spindles
• Collet size of 0.196 inches (5.00mm) with a minimum capacity of 0.177 inches (4.5mm)
• 0.02mm TIR for precision concentricity in high-speed applications
• Single-unit packaging suitable for direct replacement or tooling inventory

Compatibility

Designed as a standard replacement collet for ER11 collet holders and spindle systems that accept the ER11 collet standard.

Installation Notes

Installation is performed by machinists or toolroom technicians during spindle tooling setup. The spindle must be fully stopped and de-energized before inserting or removing collets. Use the appropriate ER11 collet nut and a calibrated torque wrench rated for the spindle specification — do not overtighten, as this can distort the collet and increase runout. Inspect the collet bore and mating surfaces for debris or wear before seating.
