Product Description
Our CNC tabletop mill is perfect for the customer looking for a mini CNC milling machine to make small, precision parts. All our milling machines are made in the USA, and our customer service is second to none. Although our machines are small, they can produce high-quality precision parts. Our CNC mill will not only cut wood and plastic but is also rigid and accurate enough to cut aluminum and steel parts. This mill is a desktop-size machine with full-size machine precision and accuracy.
Notes on ordering a metric mill
Most of our cutting tools, like center drills, are manufactured in a fractional size. If you have a metric machine with metric holders, like collets or end mill holders, you will need to order fractional holders to accommodate our cutting tools.
