Modulus Arms SpeedMILL™
Please Note: The Modulus Arms Router Jig Extreme™ requires the use of one of our SpeedMill™ end mills.
The Modulus Arms SpeedMILL™ harnesses the power of a handheld router to produce an exceptionally smooth finish with no prior experience required. The SpeedMILL™ utilizes a thermal fit tool coupler which attaches directly to your router. This prevents the end mill from coming loose from the collet during milling, which is a common issue with other types of jigs.
The steel coupler portion of the 80% lower jig tool is heated, causing it to expand and accept a 5/16" diameter solid carbide end mill, which is specifically designed for router based 80% lower milling. The end mill is thermal fit into the tool holder so it will not slip out during use. The end mill portion of the SpeedMILL™ can be replaced by the customer by heating the steel coupler with a torch.
The length of the carbide end mill portion of the SpeedMILL™ has been reduced to just 1.5 inches. This is under half the length of any other type of end mills designed for router based milling in an 80% lower jig. This reduced length results in an ultra-rigid milling tool that produces a mirror finish in record setting time.
