Rego-fix 1111.04763 ER11 Collet 3/16 Inch

Product Description

The REGO-FIX 1111.04763 is an ER11 precision collet designed to hold 3/16 inch (0.1875 inch) round shank tooling in ER11-compatible collet chucks. It delivers a total indicated runout (TIR) of 0.0002 inches, supporting tight-tolerance machining applications where concentricity directly affects finished part quality. The overall length is 18mm and the overall diameter measures 11.5mm. This collet is installed by machinists and CNC setup technicians working on mills, machining centers, routers, and any spindle system fitted with an ER11 chuck.

This collet is suited for light-duty milling, drilling, reaming, and tapping operations using 3/16 inch shank tooling. The ER11 form factor is common in compact machining centers, benchtop CNC routers, and high-speed spindles where a small collet nose diameter is required. It is a direct-install replacement for worn or damaged ER11 collets of the same bore size in production and toolroom environments alike.

Key Features

• 3/16 inch (0.1875 inch) bore accepts standard round-shank tooling of that diameter
• 0.0002 inch TIR for high-precision, low-runout clamping
• 18mm overall length fits within standard ER11 chuck depth envelopes
• 11.5mm overall diameter conforms to the ER11 collet series profile
• Single-piece quantity allows targeted replacement without excess inventory

Compatibility

Designed as an OEM-style replacement ER11 series collet for use in any ER11-standard collet chuck accepting a 3/16 inch bore collet.

Installation Notes

Installation is performed by a machinist or CNC technician. Always power down and lock out the spindle before removing or seating a collet. Ensure the collet taper and chuck bore are clean and free of chips or coolant residue before seating. Tighten the collet nut to the chuck manufacturer's specified procedure using the correct ER11 spanner wrenches - never use makeshift tools that can damage the collet ring or chuck threads.
