Quantity:

Affectionately named "Big Balls" by other CNC'ers, the Big Stiffy series 1/2" radius ball nose bit (1" inch diameter) for CNC routers (also known as a "bull nose") is for bigger radius accent work when you want your job done fast and clean. With a 1/4" shank, it is suited well for large radius CNC woodworking projects 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.

This Big Stiffy series 1/2" radius ball nose bit (1" inch diameter) for CNC routers (also known as a "bull nose") is for bigger radius accent work when you want your job done fast and clean. With a 1/4" shank, it is suited well for large radius CNC woodworking projects to remove large amounts of wood 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 Ball Nose? 2 reasons. The first is, that this bit has extra mass, which absorbs vibration you'll find in other large CNC bits. This eliminates something called 'chatter'.

Chatter is marks left in the wood which looks a little wavy. Chatter needs to be sanded out. The extra mass of the 1-inch ball nose, or bull nose, is a big benefit when you want to reduce your post-project finishing on your CNC router project.

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, with these 2 unconventional changes in the 1-inch ball nose bit for CNC routers, the potential for chatter is almost eliminated.

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