Product Introduction
WNMG-M3 is an 80° hexagon negative-type carbide turning insert. The M3 geometry is specially designed for stainless steel semi-finishing, paired with two professional stainless steel nano-coated grades: BP2215 and BP2225. The 90° approach angle design effectively avoids machining interference, making it suitable for universal semi-finishing of various stainless steels. The special groove design provides stronger versatility, and the special material combination enables cutting at low-medium-high speeds with excellent cutting performance. Both grades adopt nano coatings with low friction coefficient, effectively reducing adhesion between workpiece and cutting edge and suppressing built-up edge. It can perform multiple turning operations including external turning, facing and profiling, delivering efficient and stable performance in both dry and wet cutting.
