Parlec C50-50SF315-9 Shrink-fit Holder CAT50 0.5 in

Product Description

The PARLEC C50-50SF315-9 is a shrink-fit tool holder adapter with a CAT50 taper shank, designed for high-speed CNC machining centers that require precise, balanced tooling. The holder accepts a 0.5 inch bore diameter and provides a 3.15 inch projection from gauge line. Built-in through-coolant capability directs cutting fluid directly to the tool tip. With a nose diameter of 0.94 inches and a clamping depth of 1.85 inches, this holder delivers rigid tool retention suited for demanding milling and drilling operations. It is balanced to 15,000 RPM, making it appropriate for high-speed spindle applications. Machinists and tooling technicians working on production CNC equipment are the primary installers.

This adapter is intended for use on CAT50-spindle machining centers in production and job-shop environments, both in horizontal and vertical configurations. The shrink-fit design eliminates the mechanical components of collet or side-lock holders, providing high concentricity and grip strength. Through-coolant support makes it well suited for deep-hole drilling, reaming, and other operations where flood coolant at the tool tip improves chip evacuation and tool life. The 15,000 RPM balance rating accommodates high-speed machining strategies common in aerospace, automotive, and precision mold work.

Key Features

• CAT50 taper shank for direct mounting to CAT50 machining center spindles
• 0.5 inch bore diameter accepts standard shrink-fit tooling shank
• 3.15 inch projection provides clearance for deep-cavity and complex-workpiece access
• Through-coolant design channels cutting fluid to the tool tip for improved chip evacuation
• Balanced to 15,000 RPM for high-speed spindle compatibility
• 1.85 inch clamping depth for secure, high-rigidity tool retention

Compatibility

Designed as an OEM-style shrink-fit tool holder for machining centers equipped with a CAT50 taper spindle interface.

Installation Notes

Installation requires an induction shrink-fit heating unit to expand the bore before tool insertion; do not attempt to force tooling in or out without proper thermal equipment. Confirm the spindle and holder are fully powered down and the machine is in a safe state before changing tooling. Verify the tool shank diameter matches the 0.5 inch bore specification and that the coolant through-hole is clear and unobstructed before mounting. Follow the machining center manufacturer guidelines and applicable shop safety standards when handling heated components.
