End mill workpiece revolution feed rate machining method air blow higher feed rates and 4 times longer tool life compared to competitor end mills ! ball nose, 3 flute, taper neck, for hardened materials 89 different sizes available. 9,600mm/min (0.3mm/t).

F [in/min] = n [rpm] fr [in/rev] = 1500 rev/min 0.004 in/rev. ≈ 6.0 in/min. note that these speed and feed values are guidelines assuming adequate (flooded) lubrication, workpiece stiffness and drill depth less than 3 drill diameters (0.75″).

a tool with a low flute count (2 to 3) has larger flute valleys and a smaller core. as with loc, the less substrate remaining on a cutting tool, the weaker and less rigid it is. a tool with a high flute count (5 or higher) naturally has a larger core. however, high flute counts are not always better.

Feed rate is calculated using the following equation: feed = n x t x z. n = number of cutting edges (flutes) t= chip load (chip per tooth) is the amount of material, which should be removed by each tooth of the cutter as it rotates and advances into the work. (mm per tooth) z= rpm, the speed at which the cutter revolves in the spindle.

Note: varying conditions can easily require adjustments. • feed equals .001 per revolution for every 1/16 of drill diameter, plus or minus .001 on the total. • speed equals 80 surface feet per minute in 100 brinell hardness material and the speed should be reduced 10 surface feet per minute for each additional 50 points brinell hardness.

the calculated speed is 2,064 rpm and the linear feed is 8.3 ipm. the thread diameter of a 9/16 thread is .562”, which is used for the inner and outer diameter in both adjustments. after plugging these values into the equations below, the adjusted internal feed becomes 2.8 imp, while the external feed becomes 13.8 ipm.
