Confirm SpeedMill Type

We strongly recommend all customers to only use our proprietary end mill, the Modulus Arms SpeedMill™ with our 80 lower jig. 

Please see the chart below for which routers we recommend to use with our corresponding SpeedMill™ versions (there are 4). You can also pick up a Tool Kit if you want spare tools.

If your router is not on any of the lists, then it is not compatible with our products and we do not recommend using it to complete an 80 lower with Router Jig Extreme™. Please note that all routers that use V4 will need the Large Router Plate. ma-routerchart-website-01.jpg
