See a Quick Way to Deburr Holes in Contoured Surfaces
This video shows a device that enables machine tools to quickly deburr both sides of through holes in elliptical and contoured surfaces.
These universal deburring tools use a proprietary TiN-coated carbide blade that is said to achieve fast feeds and speeds and provide long tool life. COFA tools are available sizes ranging from 0.157 to 1.614 inch (4 to 41 mm). A cassette option is available for larger holes.
