Chipbreaker/Finisher Down Cut 3/8" Cut Diameter, 3/8" Shank, 1-1/8" Cut Length, 3" Overall Length

If you want very fast cutting speeds and work with natural woods (hard and soft), and you want a great finish at the same time, this is the end mill to use. The end mill appears similar to a roughing (hog) end mill, but doesn't exhibit as many serrations. The geometry will provide a flat surface


This is one of the best end mills for single pass (full depth) cutting at very high speeds. The chip load per tooth for the 3/8" cut diameter end mill is .019 to .021 (hard woods). The IPM for this end mill at 18000 RPM is: IPM = 18000 x 2 x .019 = 684 IPM. Helix angle 30 degrees.

Some Information about End Mills (Rotational Cutters) for CNC Machines
I receive a healthy dose of questions about end mills and which ones that I use. I usually respond with answers like, my end mill will probably differ from your end mill. So, what is this thing called an end mill anyhow? If you are new to CNC machining and routing, you may have never heard of the thing. I could imagine googling something like, "CNC bits". Using the terminology "bit" is not all that incorrect. Bits are commonly referred to as drill bits, but routers use router bits. If you're looking to cut various metals and composites, end mills are the tools of choice. However, end mills will also work on wood, depending on the type of end mill selected.
