An Improvement on the Saw-Max

The cutting wheels on this saw are 3.5 inches and 4 inches in size. At first glance, the Dremel US40-03 is a heavier duty and more functional upgrade of the Saw-Max. While the Saw-Max was impressive, this Ultra-Saw appears to more useful and durable.


The US40-03 can cut through your metal pieces with ease; for example, rebar and metal tubing. It is also capable of removing material or smoothing surfaces using the grinding and surfacing attachment. Once you pop in the offset 4-inch wood cutting wheel, you can work on your wood projects with ease. This unit has a vacuum adapter available, but you’ll need to use a separate attachment that is not included in the US40-03 kit.

A side handle in the package will be handy when you are handling both cutting and grinding applications. The US40-03 kit has the saw itself, a 4-inch carbide wood cutting wheel, two 3.5-inch metal cutting wheels, a 3.5-inch masonry-cutting wheel, a 4-inch carbide wood flush cutting wheel, a US820 side handle, and a handy kit bag.
