<p>The <em><strong>Big Stiffy</strong></em> series 60-degree v-bit for CNC routers is larger, and cuts deeper, than the typical 60 deg v bit. The extra body size lets you maximize your carve time while also leaving a clean cut.</p> <p>With a 1/4" shank, it is the go-to 60 deg carving v-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.</p> <p>To see how effective your <em><strong>Big Stiffy</strong></em> 60-degree v-bit is, watch this <a href="https://youtu.be/L-mCsobn0nc">YouTube video</a> of a <strong>very large</strong> 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.</p> <p>Why is it called the <em>Big Stiffy</em>? Overall, the bit body has more mass and has a slightly shorter shank. This little design modification on your 60 degree v-bit  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.</p> <p><em>This bit has a carbide blade brazed to a 4140 body.</em></p>
