The Big Stiffy series 90-degree v-bit CNC router bit with 1/4 shank is larger, and cuts deeper, than the typical 90 deg v bit. The extra body size lets you maximize your carve time while also leaving a clean cut.
With a 1/4" shank, it is the go-to 90 deg carving bit for home-based CNC'ers when it comes to larger projects when you are large v carves and chamfers on your CNC router woodworking projects. The 'super-shear' blade design is designed to leave exceptionally clean cuts at higher feed rates. This is the v bit to use when your v-carved letters are wider than 1/4" wide.
To see how effective your Big Stiffy 90-degree v-bit is, watch this YouTube video of a very large CNC router project completely carved in 11 minutes using the same size 120-degree V bit. The 60 deg grooving bit is designed to give you the exact same performance.
Why is it called the Big Stiffy? Overall, the bit body has more mass and has a slightly shorter shank. This little design modification keeps your bit stiffer during cuts, which gives you a 50% improvement in your surface finish. In other words, the potential for chatter is virtually eliminated.
