Sandvik Coromant 8107502 Modular Tool Holding Adapter HSK63A

Product Description

The SANDVIK COROMANT 8107502 is a modular tool holding system adapter designed for CNC machining centers and milling applications that use HSK63A spindle interfaces. It bridges the machine spindle to a C4 modular connection, enabling quick tool changes within a modular tooling system. The adapter features a 3.1496-inch projection and a body diameter of 1.5748 inches, making it suited for applications where precise axial reach and rigid tool coupling are required. Through-coolant capability is built in, supporting high-pressure coolant delivery directly to the cutting edge. This component is installed by machinists, tooling engineers, and CNC setup technicians.

This adapter is used in production and job-shop environments where HSK63A-spindle machines are paired with modular tooling systems using C4 connections. Typical applications include multi-axis milling, boring, and turning-center live tooling setups. The modular system size is 63 with a C4 modular connection, and the overall length is 3.9370 inches. It is well-suited for shops standardizing on a common modular tooling platform to reduce changeover time and increase tool inventory flexibility.

Key Features

• HSK63A taper interface for rigid, high-speed spindle connection
• C4 modular connection size for compatibility with Coromant Capto-style modular tooling
• Through-coolant capable for direct high-pressure coolant delivery to the tool tip
• 3.1496-inch (80.000 mm) projection for precise axial reach
• 1.5748-inch (40.000 mm) body diameter for stable clamping and low runout
• Sold individually, minimum order quantity of 1

Compatibility

Designed for use with HSK63A spindle interfaces and C4 modular tooling connections. Intended for CNC machining centers configured for modular tool holding systems using a size 63 modular platform with C4 coupling.

Installation Notes

Installation should be performed by a qualified machinist or tooling engineer. Power down and lock out the machine spindle before mounting or removing the adapter. Ensure all mating surfaces on the HSK63A spindle and C4 coupling are clean and free of chips or burrs before assembly. Torque the clamping mechanism according to the machine tool manufacturer specifications, not those of the adapter alone, and verify runout with a test indicator after installation.
