Nano Blue High Hardness Coating Micro Boring Tool MNR Small Aperture CNC Internal Hole Tungsten Carbide Tool Holder
This MNR small-bore boring tool is forged from premium solid tungsten carbide with advanced nano-blue high-hardness coating. Its robust shank delivers outstanding rigidity, effectively suppresses cutting chatter, and ensures stable precision micro boring for tiny holes on Swiss-type CNC automatic lathes.
The precision-ground sharp cutting edge greatly reduces built-up edge during long-time continuous internal boring operations. The wear-resistant nano-blue coating offers excellent heat dissipation, delivering fine surface finish and consistent dimensional accuracy for steel and stainless steel parts.
Engineered specifically for tiny-aperture internal boring tasks, it adapts perfectly to confined inner cavity spaces of small parts. It prolongs tool service life, cuts tool-change downtime, and notably lifts overall efficiency for mass production of miniature precision components.
