® 17 Drill Inserts and Holders Recommended Speeds and Feeds Speed and Feed Recommendation Example: If recommended speed and feed is 61M/min and 0.20 mm/rev for a 3 x diameter or 5 x diameter holder, then the speed and fees using a 7 x diameter holder in the same application would be 48.8M/min and 0.16mm/rev. Example: 61 M/min - 0.80 = 48.8 M/min 0.20 mm/rev - 0.80 = 0.16mm/rev • The speeds recommended for AM200® 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 machie 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. Formulas: mm/min = RPM . mm/rev m/min = RPM - 0.003 - DIA RPM = M/min - 318.47/DIA .80 Multiplier for 7 x Diameter
