Sandvik Coromant 6408301 CAT50 to Capto Taper Adapter

Product Description

The SANDVIK COROMANT 6408301 is a CAT50-to-Capto taper adapter designed to interface CAT50 spindle tooling with Capto modular connections on CNC machining centers. It features a C4 inside modular connection, a 60 mm projection, and a 40 mm nose diameter. Through-coolant capability allows cutting fluid to pass directly through the adapter to the tool, supporting deep-hole drilling and high-performance milling applications. The overall length is 161.80 mm. This adapter is installed by machinists and CNC tool crib technicians performing tooling changeovers or machine conversions that require bridging two different tooling standards.

This adapter suits CNC machining centers equipped with CAT50 spindles where Capto modular tooling is the preferred downstream interface. It is appropriate for both production shops and toolrooms transitioning tooling systems, and for facilities standardizing on Capto modular tooling across mixed-spindle equipment. The C4 Capto connection size is suited to medium-duty cutting applications including milling, boring, and turning on horizontal and vertical machining centers.

Key Features

• CAT50 outside taper interfaces directly with CAT50 spindle receivers
• C4 Capto inside modular connection enables use of Capto tool bodies downstream
• 60 mm projection provides clearance between spindle face and workpiece
• 40 mm nose diameter supports positive tool registration
• Through-coolant design delivers cutting fluid directly to the cutting edge
• Overall length of 161.80 mm accommodates standard reach requirements on vertical and horizontal machining centers

Compatibility

Designed for use with CAT50 spindle machines requiring a transition to Capto C4 modular tooling connections. Specific compatible machine models or replaced part numbers were not provided in the available data.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. The machine spindle must be fully powered down and the tool changer disabled before mounting or removing the adapter. CAT50 tapers must be cleaned and inspected for damage or contamination before seating the adapter, as surface defects will affect runout. Verify draw-bar pull force meets machine specifications and confirm through-coolant connections are properly sealed before resuming operations.
