This MGR 4B1.0 L15 H1.0 small-bore internal grooving cutter adopts integral solid tungsten carbide shank with premium wear-resistant coating. The 4mm diameter shank delivers outstanding rigidity, effectively suppresses cutting vibration and ensures stable slotting and grooving for precision metal workpieces in confined tiny holes.
Its precisely optimized grooving edge geometry achieves smooth chip evacuation even in extremely narrow inner bore spaces. The heat and wear resistant coating reduces built-up edge, delivering clean groove profiles, excellent surface finish and consistent dimensional tolerance for steel and stainless steel workpieces.
Specially designed for ultra-small bore precision grooving and light parting, it is fully compatible with Swiss-type CNC automatic lathes. Compact structure fits limited working space, extends tool life, cuts changeover downtime and boosts mass production efficiency of miniature precision components.
