Parlec C40BC-75SM600 Shell Mill Holder CAT40 6 in

Product Description

The PARLEC C40BC-75SM600 is a CAT40 taper shank shell mill holder designed for rigid, precise mounting of shell mill cutters in CNC machining centers. With a 6-inch projection from flange to nose end and a 3/4-inch pilot diameter, this holder positions shell mill cutters with the clearance and stability needed for face milling and shoulder milling operations. The lock screw thread size is 3/8-24, using a 75LS lock screw. Installation and setup are handled by CNC machinists and toolroom technicians working with CAT40-spindle vertical or horizontal machining centers.

This shell mill holder is suited for use in production and job-shop environments where shell mills in the 1-3/4 to 2-inch cutting diameter range are run. The 6-inch flange-to-nose projection makes it practical for applications requiring additional reach or clearance over fixtures and workpiece features. Through-coolant is not supported on this holder, so flood or mist coolant delivery must come from an external source rather than through the tool.

Key Features

• CAT40 taper shank for direct mounting in CAT40-spindle machining centers
• 6-inch projection from flange to nose end for extended reach applications
• 3/4-inch pilot diameter for accurate shell mill registration
• Accepts shell mills in the 1-3/4 to 2-inch cutting diameter range
• 3/8-24 lock screw thread with 75LS lock screw included
• No through-coolant - compatible with external flood or mist coolant systems

Compatibility

Designed for use with shell mills having a 3/4-inch pilot bore in the 1-3/4 to 2-inch cutting diameter range, mounted in CAT40-spindle machining centers. Uses a 75LS lock screw.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machining center spindle before mounting or removing any toolholder. Seat the CAT40 taper fully into the spindle and torque the drawbar or retention knob to the machine manufacturer's specification - do not rely on hand-tightening alone. Verify shell mill seating against the pilot and face before running the spindle.
