Once the type of deburrer for the job has been decided, you will need to choose a tool of the correct size. Both the hand-held chamfer bit and the deburring cutter are available in different sizes
Head diameter
A deburring tool’s head diameter refers to the measurement across the widest part of the head. If this measurement is given, it indicates the maximum diameter of hole that particular model can deburr.
Diameter of cut
More commonly, however, the deburring tool’s ‘diameter of cut’ will be listed. This information usually consists of two measurements – the minimum and maximum diameter of cut.
For example, a tool with a 5 -13mm (13⁄64 – 33⁄64) diameter of cut will deburr holes of between 5 and 13mm in diameter.
Angle
Deburring tools can be purchased to give different degrees of angle to the chamfer.
The most commonly used size for tools which produce a deburred chamfer is 90 degrees.
Depending on the manufacturer, there are other angles available for purchase, ranging from 60 up to 140 degrees.
The angles can vary, but all work around this basic principle:
