Tool failure can cause serious injury. To prevent: - When using holders without support bushing, use a short T-A Pro holder to establish an initial 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 information and procedures. Factory technical assistance is available for your specific applications through our Application Engineering department : appeng@alliedmachine.com. WARNING IMPORTANT: The speeds and feeds listed above are a general starting point for all applications. Refer to the coolant recommendation chart for coolant requirements to run at the recommended speeds and feeds. Factory technical assistance is available through our Application Engineering department. For 7xD, 10xD, 12xD, and 15xD holder lengths, see adjustment example above.
