Product Description

About the Sherline CNC NexGen Benchtop Mill

Our CNC benchtop mill is perfect for the customer looking for a mini CNC milling machine to make small, precision parts. The NexGen milling machine offers three directions of travel, and there are four additional directions that the headstock spindle can be positioned to do drilling or milling on your part from virtually any angle.

All our CNC 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.
