The speedway double cut burr is an ingenious idea , both rough and fine cutting edges on one tool .
These burrs are made to be used on a wide range of materials .
With aluminium being the softest of these materials , use of these on cylinder heads ensures maximum lifespan of the cutting edge. Anyone who has actually used an aluminium burr knows that most of the time they have a tendency to grab at the worst of times , the double cut edge on these provides extra clearance for material removal so they have a rapid removal rate without being too aggressive .
Again the double cut comes into play when wanting to semi finish , we recommend lubricating the tool with cutting oil for best removal and finish with these tools
contains a perfect range for doing all tasks
