Use Any Sized Bit With Your Makita / Dewalt Router (Shapeoko)

About: Hello, I'm Bruce. I'm a student in Belgium. I have a wide variety of interests: electronics, computers, technology, ... In my spare time I spend a lot of time on: projects, exploring the internet, cycling. ...

I got a desktop CNC router from Carbide 3D a shapeoko XL, with it came a few American sized router bits that won't fit the regular European Makita or Dewalt routers without an adapter. Somewhere on the internet I read about using an ER11 Colet as an adapter. This will help you to use any sized biy with your CNC.
In this instructable I'll explain how you can make your own adapter quick and easy.

Step 1: Get the Requiered Parts

Get the shaft for the ER11 holder. This shaft will fit the 8mm collet from Makita or Dewalt.

Get the ER11 collets 15PCS. These collets will fit most CNC router bits.

Step 2: Cutting the ER11 Shaft to Length

  1. Place a router bit into the router
  2. Mark how deep it enters the router
  3. Measure the depth of the marked line
  4. Cut the ER11 shaft to size with an angle grinder
  5. Smooth the edges with a file

Step 3: Done

Now you can use most common bit sizes in your machine.
