مثقاب كربيد مخروطي بنهاية دائرية 3/8 × 3/4 بوصة

Took this tree burr to some tight inside corners on a steel bracket, and the radius end saved me from having to switch bits. Cuts smooth without grabbing, even at moderate speed.

I’ve been using this burr on aluminum and it leaves a surprisingly smooth finish with no clogging. The tree shape with the radius end reaches into tight corners better than my old straight bits.

Finally, a burr that doesn’t chatter or clog up halfway through a job—the radius tip on this 3/8" tree shape glides through aluminum like butter. Used it for smoothing out a weld joint on a custom bracket, and the finish came out far cleaner than I expected from a single pass.
