IMPORTANT: The speeds and feeds listed above are a general starting point for all applications. Refer to the Coolant Recommendation charts for coolant requirements to run at the recommended speeds and feeds. Factory technical assistance is available through our Application Engineering department. See adjustment examples above. Tool failure can cause serious injury. To prevent: - When using holders without support bushing, use a short T-A 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.
