This is a great bit for carving on my CNC machine. With the settings right when doing the layout, barely any sanding was required to carve these Christmas ornaments I made. I cut 60 of them, and the bit still seemed to work as well on the last one as it did on the first. This was surprising because these were cut from Mahogany and required a total about 20 hours of cutting. If you look closely at the picture, this bit was capable of adding the detail of the scarf on the snowman, which is impressive since the ornament is only 3 1/2 tall.
this is the third bit I've bought from spa tools they work great
Pro- As my first tapered ball end mill I was reluctant but immediately pleased and impressed with its rigidity and performance. I've run somewhere around 5 hours of detailed 3d finishing paths in oak and its holding its edge.
Great finish left by this cutter.
No cons at this point after using the bit in several types of wood.
I use this bit 2-3 times a week over the course of a year and it looks brand new and cuts like it too. Hint, I clean the bit after every use and it helps.
