Bordo Express Cut Burrs A lso referred to as Double Cut Burrs, Express Cut Burrs are general purpose burrs designed for rapid stock removal and improved operator control. Chip size is reduced and lower tool speeds can be used compared with standard cut burrs.
Applications
Express Cut Burrs are ideal for use in
carbon steel
cast iron
high strength steel
stainless steel
steel castings
steel welds
titanium alloy and
fibreglass composite
Usage
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 cause chipping
Do not sink the burr for more than one third of its periphery
