Parlec C40-50SF315-9 Shrink-fit Tool Holder CAT40

Product Description

The PARLEC C40-50SF315-9 is a shrink-fit tool holder adapter with a CAT40 taper shank, designed for high-speed CNC milling and machining center applications. It accepts a 0.5 inch bore diameter and delivers 3.15 inches of projection from the gauge line, with a 0.94 inch nose diameter and 1.85 inches of clamping depth. Through-coolant capability directs cutting fluid directly to the tool tip for improved chip evacuation and thermal control. The holder is balanced to 20,000 RPM, making it well-suited for high-speed machining operations. Machining shops, tool crib technicians, and CNC setup personnel are the primary users of this type of tooling component.

This shrink-fit holder is intended for use on CAT40-spindle vertical and horizontal machining centers in production shop and job shop environments. The 0.5 inch bore accommodates end mills, drills, and other round-shank cutting tools commonly used in steel, aluminum, and composite machining. Through-coolant routing supports high-pressure coolant systems where chip control and tool life are critical factors. The 3.15 inch projection length suits applications requiring clearance past part features or fixturing.

Key Features

• CAT40 taper shank for standard V-flange spindle compatibility
• 0.5 inch bore diameter with 1.85 inch clamping depth for secure tool retention
• 3.15 inch projection length for reach over part features or fixtures
• Through-coolant construction supports high-pressure coolant delivery to the cutting edge
• Balanced to 20,000 RPM for high-speed machining center use
• 0.94 inch nose diameter for reduced interference in tight-clearance setups

Compatibility

Designed as an OEM-style shrink-fit tool holder for CAT40-spindle machining centers accepting 0.5 inch shank cutting tools with standard V-flange drive.

Installation Notes

Shrink-fit holders require an induction heating unit to thermally expand the bore before tool insertion - do not attempt to press or hammer cutting tools into the bore. Power down and lock out the machine spindle before changing tooling. Confirm the tool shank diameter matches the bore specification exactly, as shrink-fit retention depends on precise interference fit tolerances. Always verify holder balance and runout with appropriate gauging before running at elevated spindle speeds.
