Save me cash and works great
I cnc route alot of signs for customer and v-carve near all of them. I went though alot of 90* bits.Then I found this... never going back to standard v bits. I have had to run my spindle about 20% faster to accommodate only 1 cutting edge. The finish is glass smooth on all types of wood I have used it with so far. After about 30 signs I had to rotate the carbide insert once.
