With a revolutionary 80% lower jig, comes a revolutionary end mill. Our all-new Speedmill for the Easy Jig® Gen 3 is the most efficient and effective milling system on the market today. Pairing our top-of-the-line end mill with our new heat-shrink tool holder, the combination virtually eliminates deflection and total runout.

It features:

  • Solid Carbide End mill
  • Optimized Fluting for Aluminum
  • Extremely Rigid Support
  • Direct-Thread to your Router
  • Longer Lasting, Averaging 5-7 Lowers per bit for Experienced Users
  • Made in the USA

We have made this a direct-thread system, to make sure you have the most solid lock-up and repeatability when it comes to milling your lower to CNC level results. Because of this feature, each router will require a different size selected when you order.
