Parlec C50-10SM8 Shell Mill Holder CAT50 1 in Pilot

Product Description

The PARLEC C50-10SM8 is a CAT50 taper shank shell mill holder designed for use on CNC machining centers requiring high-precision face milling setups. Built on a PC6 modular connection, it features a 1-inch pilot diameter, a 2.25-inch nose diameter, and an 8-inch projection from flange to nose end. Through-spindle coolant delivery is supported, though the Parlec 10LSC accessory is required to enable that function. The holder is balanced to 8,000 RPM and holds a Total Indicator Runout (TIR) of 0.005 mm, making it suitable for demanding production environments where concentricity and stability at speed are critical. Weighing 15 pounds, this is a substantial toolholder intended for large-format machining.

The C50-10SM8 is applied in horizontal and vertical CNC machining centers equipped with CAT50 spindles. The 8-inch flange-to-nose projection suits applications where extended reach is needed to clear fixtures, deep pockets, or large workpiece profiles. The PC6 modular interface allows the holder to accept compatible shell mill arbors for face milling, shoulder milling, and similar operations. Typical users include machining center operators and tooling technicians in job shops and production facilities running heavy-duty milling operations on ferrous and non-ferrous materials.

Key Features

• CAT50 taper shank for use with standard CAT50 spindle interfaces
• PC6 modular connection accepts compatible shell mill arbors
• 8-inch flange-to-nose projection for extended-reach milling setups
• Through-spindle coolant capable - requires Parlec 10LSC for coolant-through operation
• Balanced to 8,000 RPM for stable high-speed face milling
• TIR of 0.005 mm for precise concentricity in production applications

Compatibility

Designed for use with CAT50 spindle machines utilizing the PC6 modular connection standard. Through-spindle coolant functionality requires the separate Parlec 10LSC coolant-through accessory.

Installation Notes

Installation should be performed by a qualified machining center operator or tooling technician. Power down and lock out the machining center spindle before mounting or removing the toolholder. Verify the CAT50 taper and spindle pocket are clean and free of chips or debris before seating the holder. Confirm the lock screw thread size of 1/2-20 when selecting draw studs or retention knobs, and torque all fasteners per the machine tool builder specifications.
