CAT40 Tool Holders

CAT40 Tool Holders — New & Used

CAT40 tool holders are the industry standard for medium-to-heavy-duty milling and CNC machining. Designed for precision and balance, CAT40 holders deliver exceptional concentricity, vibration resistance, and tool life in both high-speed and general-purpose machining applications. Common configurations include ER collet chucks, end mill holders, shell/face mill arbors, tapping heads, and drill chucks—ideal for 3-axis, 4-axis, and 5-axis CNC mills.
