Parlec C50-20SA6 Milling Machine Arbor 2in CAT50

Product Description

The PARLEC C50-20SA6 is a stub-style milling machine arbor designed for use with CAT50 taper spindles in horizontal and vertical milling operations. Built with a taper shank interface, this arbor accepts shell mills and face mills with a 2-inch bore diameter. The overall length is 9 inches, with a 6-inch projection from the spindle face and a shoulder-to-nut length of 5.25 inches. At 12 pounds, the C50-20SA6 is a solid, rigid tool holder intended for heavy milling applications where runout control and secure cutter retention are critical. It ships with three spacers and an arbor nut included.

This arbor is used in CNC machining centers and manual milling machines equipped with CAT50 spindle tapers, common in production shops, job shops, and industrial maintenance environments. The stub arbor design keeps the cutter close to the spindle nose, reducing overhang and improving rigidity during face milling, side milling, and slotting operations. Installation is performed by machining professionals and toolroom technicians working with large-bore shell mill cutters.

Key Features

• CAT50 taper shank for positive spindle engagement in standard CAT50 machining centers
• 2-inch arbor bore diameter accommodates standard shell mill and face mill cutters
• Stub style with 6-inch projection minimizes overhang and maximizes cutting rigidity
• 5.25-inch shoulder-to-nut length provides precise cutter positioning along the arbor
• Includes three spacers and an arbor nut for complete out-of-box setup
• 9-inch overall length suits a wide range of vertical and horizontal mill configurations

Compatibility

Designed for use with CAT50 taper spindle machining centers and milling machines accepting shell mill or face mill cutters with a 2-inch bore diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or removing the arbor. Inspect the spindle taper and arbor taper for nicks, chips, or contamination before seating; even minor debris can cause runout. Torque the retention knob or drawbar to the machine manufacturer's specification, and verify cutter seating and spacer stack before initiating a cut.
