This undercut end mill is great for all of the same operations as a standard flat end mill, but with other benefits. For hybrid printing and milling operations, the undercut allows vertical sidewalls to be milled from bottom up while leaving a few print layers at the top for the next additive step. For low stiffness setups, the undercut also helps to minimize chatter on deep cuts. The 45 degree angle at the top of the undercut allows for back chamfer operations. This is extremely useful for breaking edges on thru bores and other features on the bottom surface of parts.
