1/4" SN shape carbide burr, double cut, inverted cone shape, 10 degree included.
A rotary burr for deburring, weld dressing, shaping and blending in a die grinder or air tool. This one cuts 1/4" diameter with 5/16" of cut on a 1/4" shank, 2" overall.
The double cut crosses two rows of flutes, which breaks the chip up small, keeps the tool from grabbing and leaves a smoother finish with less vibration.
