Recommended Speed and Feed Example If the recommended speed and feed is 50 m/min and 0.20 mm/ rev for a standard length holder, then the speed and feed using a 3XL holder in the same applicaƟon would be 37.5 m/min and 0.18 mm/rev. 50 • 0.75 = 37.5 m/min 0.20 • 0.90 = 0.18 mm/rev

Tool failure can cause serious injury. To prevent: - When using holders without support bushing, use a short T-A® holder to establish an iniƟal hole that is a minimum of 2 diameters deep. - Do not rotate tool holder more than 50 RPM unless it is engaged with the workpiece or fixture. Visit www.alliedmachine.com/DeepHoleGuidelines for the most up-to-date informaƟon and procedures. Factory technical assistance is available for your specific applicaƟons through our ApplicaƟon Engineering Team. WARNING
