* Uncoated CPM-T15 (Cobalt) or TiN coated CPM-M4 HSS is recommended for extended tool life at the speeds and feeds shown. ** The speeds recommended for TiAIN coated tools are based on empirical data obtained under "Optimum Conditions". 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. Multiply the uncoated universal speeds and feeds by 1.15 to 1.25, when using TiN Coated Universal Drills, for materials shown without an aesterisk. This will achieve a 30% to 50% increase in your penetration rate (IPM feed). For additional information on horsepower and thrust please use AMEC's "Speed and Feed" slide charts. WARNING: DO NOT RUN UNCOATED HSS AT THE COATED SPEEDS AND FEEDS SHOWN ABOVE.
