When using the Extra Long 1/4″ Up-Cut End Mill, proper speeds, feeds, and cut depths are critical to achieving optimal performance and preventing breakage. Due to its 4″ overall length and the naturally brittle nature of solid carbide, this bit requires careful handling to avoid undue stress. Exceeding recommended parameters or pushing the bit too hard can lead to snapping, especially in demanding applications. Always consult your CNC’s guidelines and adjust for material type to ensure smooth, precise cuts and extend the life of your bit. Patience and precision are key to maximizing both performance and durability. This data serves as a general guidance only and do not warrant against bit breakage. These are conservative speeds and feeds due to the cut length on these tools Soft Woods/ Hard Woods RPM: 16,000RPM IPM : 40-55″ Max Cut depth per pass: 3/16″
