Description

The Big Stiffy series 60-degree v-bit for CNC routers is the bit to use when you want your job done fast and clean. With a 1/4″ shank, it is the go-to v carving bit for home-based CNC’ers when it comes to larger projects. The ‘super-shear’ blade design is designed to leave exceptionally clean cuts at higher feeds rates. This is the v bit to use when your v-carved letters are wider than 1/4″ wide.

To see how effective your 90° Super-Shear bit is, watch this YouTube video of an amazing lion completely carved in 11 minutes using the same size 20 degree V bit!

Why is it called the Big Stiffy? Overall, the bit length is a bit shorter than most. 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. When 60-degree v bits are longer, they tend to cause ‘chatter’ (a rough surface finish caused by tool vibration and deflection)

This bit has a carbide blade brazed to a 4140 body.
