Why Carbide Burrs Chip and Go Dull After 10–15 Minutes of Real Work (What One Shop’s Timed Trial Actually Showed)
I’ve spent twelve years watching operators burn through carbide burrs on weld cleanup, mold detail, and general metal removal. The burrs leave the toolbox sharp. Ten or fifteen minutes of actual cutting later the teeth are chipped, the finish is torn, and the guy reaches for another one. Most crews blame the brand or the material. The numbers I keep measuring point somewhere else.
