Daoqin Square PVD Coated Grooving Blade N123G2/H2/E2/K 2 200 300 400 DM215 Slotting Tool 6.0mm Hole Diameter 20-65HRC Hardness
This N123 series grooving and cut-off insert covers 3mm to 6mm cutting widths, including N123G2-0300, N123H2-0400, N123H2-0500 and N123K2-0600-0004 models with TM optimized chipbreaker. Made of premium coated carbide, it is engineered for grooving, parting and cut-off on steel, stainless steel and cast iron via CNC lathes.
The TM grade combines a high-toughness tungsten carbide substrate with durable composite coating, delivering excellent wear resistance, edge stability and anti-adhesion performance in both continuous and interrupted cutting. The optimized TM geometry ensures steady chip formation and smooth evacuation across wide feed and depth ranges.
Precision machined to standard N123 interface dimensions, these double-edged inserts fit corresponding grooving tool holders for fast indexing and reduced downtime. They deliver reliable cutting performance with high cost efficiency, and are widely applied in automotive, machinery, hardware and general precision component manufacturing.
