Description
 

This highly productive countersinking cutter is a much improved version of the traditional multi-flute milling cutter
grooves opened wide to allow for greater chip removal, high positive cut, constant profile relief (a great many regrinds), self centering countersink and work without vibration. Tool dimensions are adapted to countersink the 82° and 90° cap screws. Lubrication is recommended.
