WARNING

Tool failure can cause serious injury. To prevent: - When using holders without support bushing, use a short T-A Pro holder to establish an iniƟal hole that is a minimum of 2 diameters deep. - Do not rotate tool holders 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 department. email : engineering.eu@alliedmachine.com IMPORTANT: The speeds and feeds listed above are a general starƟng point for all applicaƟons. Refer to the coolant recommendaƟon chart for coolant requirements to run at the recommended speeds and feeds. Factory technical assistance is available through our ApplicaƟon Engineering department. For 7xD, 10xD, 12xD and 15xD holder lengths, see adjustment example above.
