Is this a dedicated chamfer cutter?
It is an end mill with a specified outside-corner chamfer. Do not substitute it for a dedicated chamfering tool without checking the required geometry.
Does overall length equal cutting depth?
No. Overall length includes the shank. Use the maximum cutting depth for the fluted section and check projection and holder clearance separately.
What distinguishes the Weldon-shank version?
The Weldon shank is part of the holder-interface selection. Match its exact diameter and holder acceptance as well as the cutting geometry.
