Metal Grinding Polishing High Speed Carving Burrs Impact Toughness
Most widely used shape. Lower cutting resistance than spiral cuts. Chips are powdery. Capable of minimization of chattering.
A large cutting depth helps to shorten the required time for cutting. Chips are needle-like. Somewhat higher in cutting resistance than a master cut, but capable of fast cutting. Hence, suitable for high-efficiency cutting processes.
Chip pocket widened to prevent clogging, enhance work performance, and help smooth chip discharge.
Recommendations For Use
• It may be necessary to alter the running speeds from those shown in the speed chart in order to achieve optimum performance.
• Harder materials require slower running speeds.
• Smaller burrs require faster running speeds.
• Long shank burrs require slower speeds for safety reasons.
• Apply constant movement and light pressure when using the burr.
• Running below the optimum speed will cause chipping.
• Running above optimum speed will cause premature tooth wear.
• Allowing the burr to become too hot may cause the braze to soften, and
cause the head to become detached from the shank.
• Using tools and collets which have become worn will encourage chipping.
• Do not sink the burr for more than one third of its periphery
