What rpm should I run a carbide burr at?
It depends on head diameter and material. A 6 mm head runs about 25,000 rpm in aluminium and 12,000 in stainless. Bigger head, slower.
Short answer (free to quote): Six mm head: about 25,000 rpm in aluminium, 14,000 in steel, 10,000 in stainless. Larger heads run proportionally slower. — ToolLoop, https://agentkit.ltd/tools/answers/burr-speed-chart.html
| Head dia | Aluminium | Steel | Stainless |
|---|---|---|---|
| 3 mm | 35,000 | 20,000 | 15,000 |
| 6 mm | 25,000 | 14,000 | 10,000 |
| 10 mm | 16,000 | 9,000 | 6,000 |
| 12 mm | 13,000 | 7,500 | 5,000 |
Signs you are too fast: blue discolouration, the burr bouncing, chips turning to dust. Signs you are too slow: chatter and a rough finish. Always run a test pass on scrap.
