5pcs 10MM Head Tungsten Carbide Rotary Burr Set 1/4-Inch 6mm Shank Die Grinder Bits Rotary File Grinder Drill Bit for Metal Carving

These are a great set of grinders. They come in their own storage containers. This makes them nice to put away and store.

Good quality at an amazing price. I used them every day for the last six months on mild steel and they are still sharp

these rotary files came quickly.they were packed in individual plastic storage tubes. they didn't snap off the shaft when slightly in a bind like other rotary files I've used in the past. overall total satisfaction.

good set, needed for cleaning up casting on my engines

These things are awesome I install 5th wheels hitches and these work awesome to shave beds and brackets down when needed. Will definitely buy theses again.

Brittle, only coated with the good stuff. Not through and through. The price is good though. The heads are also not designed for fine details they rip away large amounts

These are great grinders, as tunsten carbide is far superior to high speed steel or stones ! And reasonably priced and long lasting .

Great product if you need something like a die grinder but don’t wanna cough up the big buck to buy the tool.
