Maximum recommended speed for extra long burrs is 15000 RPM. • It may be necessary to adjust the rates shown to achieve optimum performance • Running below the optimum speed will encourage chipping • Harder materials or sticky metals such as titanium, require slower speeds • Running above optimum speed will cause tooth wear • Smaller burrs require faster speeds • Letting the tool get too hot may cause the braze to melt and detach the head of the shank • Apply constant movement and light pressure when in use • Do not sink the burr for more than one third of its periphery RECOMMENDATIONS FOR USE RECOMMENDED OPERATING SPEEDS (RPM) CARBIDE BURRS & WIRE BRUSHES
