طقم مثقاب دقيق مطلي بالماس من 30 قطعة

The assortment of bit shapes really helps with detail work, and I've been using the cone ones to smooth out some rough plastic edges on a model kit. They hold up well so far with no visible wear after a few hours of use.

The 1/8" shanks fit my rotary tool perfectly, and the diamond coating chews through steel and wood without losing its bite. I've used the ball and cone heads for engraving and the flat ones for smoothing, and they hold up way better than the cheap carbide set I had before.

The variety of head shapes in this 30-piece set has been a lifesaver for detail work, especially the pointed cone burrs. They cut through hard plastic smoothly without melting the material, and the 1/8" shanks fit perfectly in my rotary tool.
