With its 4-flute design and TiCN-coated HSS-E body, this end mill delivers steady material removal and good edge life under higher cutting speeds. The 30° helix and 12° rake angle optimize cutting forces and chip flow, helping maintain dimensional accuracy during roughing in a range of common metals. The flatted Shank provides secure seating in 12 mm tool holders, reducing run-out and improving stability in aggressive milling scenarios. The compact 26 mm length of cut enables precise entry into pockets and shoulders, while the 83 mm overall length offers reach for deeper cavities and ramping operations. This makes it a reliable, versatile choice for shops aiming to maximize productivity in free-machining steel, cast iron, and copper alloy applications.
