If you’re looking for speed to rough out your CNC router projects, the long 1/4 roughing endmill CNC router bit is the one you want!!. We call it the ‘HOG’ here at IDC Woodcraft because it literally is a hog when it comes to removing material mind-blowingly fast from your CNC woodworking project.

With a whopping 3/4″ depth of cut per pass,  80ipm plunge rate (yes, I said plunge rate), 80ipm feed rate, and 80% step-over, this bit kicks serious ass when it comes to getting material removed, so you can follow up with your finishing bit to finish your job off.

But it’s not just a time thing. Making the roughing endmill CNC router bit your workhorse for major material removal on your CNC woodworking projects, you save a ton of wear and tear from your regular up-cut, down-cut, or compression router bits. You’ll only use them to do the finishing work.

That alone extends the life of your bits significantly, saving you money for replacements. At $35-ish bucks a pop, the long 1/4 roughing endmill will 100% save you some cash. Especially when it comes to hardwood.

What is the long 1/4 roughing endmill bit good for?

  • Guitar making
  • Keepsake box making
  • Cutting boards
  • Bulky 3D carvings
  • Table legs, like Victorian table legs or French table legs
  • Other thick woodworking projects when you need to remove a lot of wood from hardwood

Plainly put, the up-cutting long 1/4 roughing endmill bit is the CNC bit to use when you need to remove massive amounts of material!

It’s not designed to make a pretty cut. It is designed for speed!

    This bit allows me to rough out my projects 4 times faster than using a typical spiral upfeed bit. It literally pays for itself with shortened machining times. What can you do with the time you will save?
