- Machining hardness reach HRC70, for the most work, rotary burr set it can replace Petiole small wheel. And their working life is 10 times longer than normal HSS Burr, 200 times longer than Petiole small wheel.
- Double-cut style has rows of cutting cut in two intersecting directions for quick material removal and a rougher finish.
- Tungsten carbide is approximately twice as stiff as steel, with a Young's modulus of approximately 530–700 GPa (77,000 to 102,000 ksi), and is double the density of steel—nearly midway between that of and gold. It is comparable with corundum (α-Al2O3) in hardness.
- They all feature toughened and hardened steel shanks that provide strength. This stops bending and reduces vibrations for an improved tool life.
