This 2 inch end mill works great and is great value. I found that the mounting screw countersink was too small for the screw that came with the mandrel. A standard socket head cap screw will do.
Very satisfied with the tool and its mandrel although the washer needed to attach the tool to the tool on the mandrel was not included. The clamp was on a spike but there was no washer or anything special. FYI, that's a 3/4" flat washer. Very happy with the cutting action of the tool once I installed it.
These tools never disappoint. Why pay more for the same quality. My insole broke at least twice due to inattentiveness and after a call to the SA with accusations, replacement parts were sent immediately. They take care of their customers like no other American company. I strongly recommend blaming the tools for this.
