Ryobi Smooth Sphere Material Removal Burr
Some projects require that “little extra” touch for completion. After removing a wide swath of materials with a course burr, the use of a smooth burr can provide that accent. The HD Seeds program has just an item from Ryobi. Their Smooth Sphere Material Removal Burr, item # A90MR04 was an appropriate choice for evaluation. The sphere head is 3/8” diameter on a 1 ½” shaft designed for use with rotary tools. The burr is recommended for use on wood or plastic at a maximum speed of 35,000 RPM.I used this burr on the accessory pencil tip unit, which permitted me to use it like a dental tool. I did not detect any draw on the motor or binding during use. Again this is another accessory bit that will expand the use and creativity of your rotary tool. This product is made in the U.S.A.

Tool is small, sharp and very effective
The smooth sphere material removal burr worked well with my 1/8th inch rotary tool. I was able to carve a finger sized pocket with it in about 15 seconds on a pine board. The surface finish was pretty smooth for the rate the material was removed at. After testing it on a pine board I carved some of a walnut shell. I was able to smooth out the interior and bore two small holes with the burr, the end result looked kind of like a monkey head for a small statue. The burr still seemed brand new after doing both of these tests. I'm excited to see what other projects I come up with that can use this nice burr.

Great accessory for woodworkers
I have two Ryobi rotary tools and I’m always looking for some good bits, especially ones that can be used for woodworking and other similar projects. I’ve wanted one of these types of burrs to do some hand texturing in some small wood pieces, and I’ve been doing some tests in some scrap wood. I’ve been impressed with the results so far. It’s easy to control and removes material quickly. I’ve been happy with this bit so far, and I’d really like to see this bit available in some bigger sizes. Definitely recommend!

The pictures for the product didn't indicate a size of the tool, but for some reason I was under the impression that it would be much larger than it was. It was tiny - much smaller than my pinky finger. I would not have bought it had I known this. It worked alright, but does not smooth wood out as polished as I'd like.
