The 17677D Thermogrip Tool Holder is a precision collet-style holder designed for machining operations where tool stability and tight run-out are critical. These holders are typically used in milling, drilling, and other CNC processes to securely grip cutting tools and maintain accuracy under load. While the exact specifications (such as shank size, clamping range, balance grade) are not provided on the IMS Supply page, Thermogrip holders are generally known for their high gripping force and thermal stability. Because detailed documentation is lacking, it would be advisable to request a datasheet or technical drawing from IMS Supply to confirm compatibility with your machine spindle and tooling.
