This Big Stiffy series 3/4" ball nose router bit (3/8" inch cutting radius) for CNC routers is your all-purpose accent bit. And it is excellent for broader juice grooves on larger cutting boards.

Sometimes called a bull nose bit, when it comes to profile work on keepsake boxes, this offers the best of both worlds...speed with a good stepover rate. And, of course, it is good for accent work when carving those bigger signs on your CNC router. Cuts fast and clean.

Your biggest advantage is the 1/2" flat sidewall gives you the ability to run deeper cuts without leaving 'witness' lines on the project.

With a 1/4" shank, it is suited well to remove large amounts of material in a single pass. The 'super-shear' blade design is designed to leave exceptionally clean cuts at higher feed rates.

Why is it called the Big Stiffy? 2 reasons. The first is, that this bull nose bit has extra mass, which absorbs vibration you'll find in other large CNC bits. The second reason is, that the overall bit length is shorter than the standard bit. 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.

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

3/4 " ball nose

I have not used it yet. Although I'm sure it will work well with shallow projects, I would prefer a longer shank to be able to do deeper.
