With a wide range of projections available from standard-length to extended-length, you are sure to find the right tool holder for your application. Fitz-Rite end mill holders are precision ground to exceed industry standards with tapers held to AT-3 and bores concentric to the taper within .0002". Fitz-Rite's internal standards ensure superior spindle contact, enhanced ability to hold tight limits, and the best wear and corrosion resistance on the market. At Fitz-Rite, our end mill holders are designed with the user in mind. Designed for machines with coolant through the spindle, our coolant-thru holders deliver a continuous flow of coolant to the workpiece without the use of expensive coolant-thru end mills. Three coolant channels, angled toward the centerline of the cut, deliver coolant right where you want it, flushing chips and extending tool life. Our extended length end mill holders allow for milling in deeper and tighter spaces. All standard sizes available to ship same day.
