Description
The KO PerfAngle™ EXT Cordless Bundle is the refined evolution of the original PerfAngle TIG tungsten grinder, rebuilt from the ground up.
Built from direct feedback from long-time users, the EXT sharpens TIG tungstens faster, is more ergonomic, and delivers better control and visibility. Also the discs last longer while keeping grinding dust contained.
It is designed for welders who care about arc consistency, puddle control, and not regrinding the same tungsten over and over.
