* TiAIN Coated C3 Solid Carbide is stocked with a geometry ideal for gray cast iron applications. C2 grade and geometry is recommended for ductile and nodular cast iron applications. ** The speeds recommended for TiAIN coated tools are based on empirical data obtained under "Optimum Conditions". Inasmuch as many applications do not exhibit "Optimum Conditions", reductions in speed parameters may be required due to excessive tool wear generated in the application. The speeds and feeds listed above are considered a general starting point for all applications. Factory technical assistance is also available for your specific applications through our Application Engineering Team. Please have item number, hole diameter, depth, material grade, BHN hardness and coolant pressure information available when you call. Additional information such as part and machine rigidity, horsepower and thrust limits, vertical or horizontal spindle, revolving or stationary tool, flood or through holder coolant are also very helpful to our Application Engineers. Speed and feed reductions are recommended, with the speeds and feeds listed above, when using extended length T-A^® holders. This is due to the large depth to diameter ratio and chip evacuation requirements associated with deeper drill depths. As much as a 20% reduction in speed and a 10% reduction in feed is recommended. For additional information on horsepower and thrust please use AMEC's "Speed and Feed" slide charts.
