Rego-fix 1111.05562 ER11 Collet 0.2188 in 7/32

Product Description

The REGO-FIX 1111.05562 is an ER11 collet designed for precision tool holding in CNC machining centers, milling machines, and high-speed spindle applications. It accepts a shank diameter of 0.2188 inches (7/32 inch) and holds a total indicator runout (TIR) of 0.0004 inches, making it suitable for close-tolerance work where concentricity matters. The overall length is 18mm and the overall diameter is 11.5mm. This collet is installed by machining technicians and toolroom professionals who require consistent, repeatable tool registration at the spindle.

This ER11 collet is used in applications where smaller spindle noses and compact tool holders are required, such as engraving, drilling, and light milling operations. The ER11 series is a widely adopted standard in both production and job-shop environments. It is suited for residential shop use as well as light industrial and commercial machining cells. Proper collet selection is determined by the shank diameter of the cutting tool being held.

Key Features

• ER11 collet series for compact spindle and tool holder applications
• 0.2188 inch (7/32 inch) bore diameter for precise shank fit
• TIR of 0.0004 inches for high concentricity and reduced tool runout
• 18mm overall length and 11.5mm overall diameter
• Single-piece package quantity - no minimum bulk purchase required

Compatibility

Designed as a standard ER11 collet compatible with ER11 collet chucks and tool holders that accept the ER11 series. Confirm spindle or chuck designation is ER11 before installation.

Installation Notes

Installation is performed by qualified machining technicians or toolroom personnel. Before inserting or removing the collet, ensure the spindle is fully stopped and the machine is powered down or placed in a locked-out state per applicable safety procedures. The collet should be seated fully into the collet nut before threading onto the chuck body. Do not exceed the recommended clamping torque range for the ER11 nut size - consult the tool holder manufacturer specifications for torque values.
