> 3 dayI’ve used this burr a few times now on billet and sheet aluminum with some wax and so far no issues. Can’t say how it’ll hold up to everyday use or heavy duty tasks, but for the occasional job it works great.

> 3 dayI used to clean up so welding. The burrs are. Eryvsharp. I didn’t use my gloves and picked up some splinters. Use your gloves when using these. I will continue using for shaping my projects.

> 3 dayI got these for my daughter, who has her own Dremel carving tool. I have use these for years as a favorite bit for starting a carving on various woods, gourds, and even tile, and soft stone. Great for other home repair projects too. They get the grinding done. Then a finish is made with high speed steel cutter, or diamond bit.

Gently press rotary tool, let speed do the work.
