Tech Tip: Indexable Milling Lead Angle and Depth of Cut

Today we're going to talk about the effect lead angles have on the depth of cut. When choosing a lead angle for your indexable mill, it's important to remember that it will affect the tools depth of cut capability. If the insert size remains the same, your depth of cut will change when the lead angle changes. For example, if you use the same insert size in a 90-degree application and a 45-degree application, the depth of cut will decrease in the 45-degree application due to the insert sitting at a steeper angle.
