What is a deburring cutter? |

|
|
||||
 |
A deburring cutter is designed for use in a machine or drill chuck, although this type of deburrer can also be used by hand for light deburring applications if a hand-held deburrer is not available. | |||
 |
The deburring cutter can be used on non-ferrous metals, wood, plastic, copper and nylon. | |||
 |
These cutters are best used in a machine (e.g. lathe, pillar drill) to drive them into the workpiece and remove burrs. | |||
 |
Most models have only one cutting edge, positioned on the side of the tool. | |||
 |
When a deburring cutter is installed in a machine, the chuck spins it in a clockwise direction. The chuck jaws grip the cutter’s shank and spin the tool at a much faster pace than a hand-powered deburrer, resulting in a much quicker and neater finish. | |||
 |
The cutter, when spinning, is then moved downwards onto the workpiece, applying a light pressure to remove any burrs. | |||
Countersinking |
||||
 |
Deburring cutters will not only remove the burrs, if they are applied under great pressure to the workpiece, there is the possibility of the cutter taking out extra material. When any extra material is removed, it will create an angled edge called a countersink. | |||
 |
Generally, these cutters are used for deburring applications, but are favoured as a countersinking tool.
They are designed to be used in a machine (lathe, pillar drill) or drill chuck for countersinking, with the option of being used as a deburrer if a countersunk hole is not required. |

 |
||||
What sizes are available? |
||||
 |
The deburring cutter is available in a range of sizes. | |||
 |
||||
 |
Deburring cutters with a hexagonal shank can be purchased in the following size ranges:
A deburring cutter is measured by the minimum size hole and the maximum size hole it can deburr. For example, a 2 – 8 mm deburring tool will deburr a hole as small as 2mm and up to 8mm in size. |
|||
 |
If the size required for the job is greater than 20mm, the tool can sometimes then be named a zero flute countersink, and a larger range of sizes is available for purchase.
These will have a round shank instead of a hexagonal shank and will be used for much larger deburring applications. |
