Large Ball and Radius Turning Tool - Designed to Cut Round Shapes or Curves in Brass, Aluminum, Steel, Wood or Plastic on your Bench Top Metal Lathe, LittleMachineShop.com (2568)

Outstanding item. Very useful

For the price it should have carbide incerts

Product is good for small light parts. It is made from aluminum and will chatter a lot if not careful.

Made of weak aluminum and it flexes so much when being used that it causes issues.

Received as advertised, with patience makes a nice ball shape on work stock end

Solid construction and built with high quality parts. Works excellent on plastic, brass, and aluminum. I wouldn't plan to do much steel work but it is possible with the right prep and finesse. Due to the nature of this tool's design and the aluminum construction of the body it's not going to cut ultra high tolerance features with a perfect finish nor is it going to take very deep cuts. However, with some practice and patience it adds value capability to a lathe, cutting features that are otherwise impossible on a manual machine. For best results, rough out your shape with a turning or grooving tool and give your work a nice polish with a medium/fine sanding block for a well blended finish.
