The 1/8″ down-cutting endmill bit (a.k.a. down bit, down cut bit, downcut bit) is the 2nd workhorse of CNC router bits when it comes to detail. It follows after the 1/4″ to do what the 1/4″ can’t reach.

There are 2 reasons you need this bit…

  1. The 1/8″ down bit removes what the 1/4″ leaves behind in pockets and around letters.
  2. It does the finish work for many projects.

The down-cut endmill is the king of CNC routers because it leaves super-crisp cuts at the top of the edges. Sanding is eliminated!

For these reasons, you want to make sure your 1/4″ down cutter is made right & built to last. That’s why these are made above industry standards and 100% tungsten carbide.

Carbide is what professional metal machinists use to make complex items like car engines. It stays sharp 50x longer than conventional CNC router bits.

You’ll want to include a collet with this bit if you do not have one. You can order that by clicking here.
