CUTTERS OF ROUND SOLID METALS Russian patent published in 2015 - IPC B23D35/00 

FIELD: process engineering.

SUBSTANCE: cutters allow the shift of their tops relative to each other in the cutting plane perpendicular to their mirror axis and have the cutting edges. The latter make the rectangle-shape gage composed of two semi-gages. Lower gage is fixed while the upper one can reciprocate in vertical plane. Note here that said cutting edges are located at larger side of rectangular gage and inclined at 30-45 degrees. To allow a perpendicular cutting, said cutting edges located at rectangular gage smaller side are inclined at 15-20 degrees. The amount of cutters tops shift in the cutting plane can make from 4-6 to 7-8 mm. Note here that the smaller magnitudes relate to cutters of round metals some 100-150 mm in diameter while larger magnitudes relate to those for cutting the round materials some 151-200 mm in diameter.

EFFECT: perfected design.
