Seco 00056663 Boring Head Taper Shank CAT40 Modular

Product Description

The SECO 00056663 is a CAT40 taper shank adapter designed to mount boring heads via a Graflex 5 modular connection. It provides a rigid, accurate interface between CAT40-spindle machining centers and modular boring head assemblies. Overall length is 4.27 inches, with a projection of 1.57 inches and a nose diameter of 1.75 inches. Coolant-through capability is built in, supporting through-spindle coolant delivery directly to the cutting zone. This adapter is installed by machinists and toolroom technicians on CNC horizontal and vertical machining centers equipped with CAT40 spindles.

This shank is suited for precision boring operations on CNC machining centers in production and job-shop environments. The Graflex 5 modular interface allows fast, repeatable head changes without removing the taper shank from the spindle. Typical applications include finish boring of bores requiring close dimensional tolerances on ferrous and non-ferrous workpieces. It is appropriate for both light and moderate material removal passes where rigidity and runout control are critical.

Key Features

• CAT40 taper shank for direct mounting in CAT40-spindle machining centers
• Graflex 5 modular connection for repeatable, tool-change-ready boring head interface
• Coolant-through design supports direct coolant delivery to the cutting zone
• 1.57 inches projection for reach clearance in typical boring setups
• 1.75 inches nose diameter provides a stable seating surface for the modular head
• 4.27 inches overall length suits standard boring head assemblies on vertical and horizontal machining centers

Compatibility

Designed for use with CAT40-spindle CNC machining centers and SECO modular boring head components using the Graflex 5 inside modular connection size.

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 the taper shank. Ensure the CAT40 taper and spindle bore are clean and free of chips or contamination before seating the shank. Verify the modular connection is fully engaged and torqued per the machining center and tooling system manufacturer guidelines before running the spindle.
