Tungaloy’s GNGA series with T-CBN is a cubic boron nitride (cBN) insert designed as a solution for sudden insert failure and uncontrollable surface roughness due to poor chip control. Compared with the conventional C-type insert with 80° cutting edge angle, the GNGA insert’s 70° cutting edge angle can create larger clearance between the workpiece and the insert during machining. The optimized geometry provides smooth chip control, preventing machined surface damage by chip packing and sudden insert fracture due to chip jamming.
These inserts are compatible with existing ISO toolholders that hold CNGA 43x inserts and are available in the following grades: BXM20 and BX360 for hardened steel; BX470 for cast iron and powder metal; and BX930 for ductile cast iron.
