Micro Endmills for Precision Machining

About NS TOOL

NS TOOL, from Japan, is the world leader in micro solid endmill cutting tools. They specialise in sub Ø6mm endmills and have a excellent range of high quality endmills from Ø 6mm down to 10 microns! They are designed for performance in a ranger of material but the performance in hard metal +60HRC is very impressive.

NS TOOL has developed their own range of original coatings that radically outperform competition brands. They deliver very impressives improvements in tool life and consistency. See Coatings ➜

A high speed machining center is required to properly utilise the small diameter tools.

We supply Air Turbine, pneumatically actuated, high speed spindles that can deliver RPM 45,000 – 90,000, and allow a normal machine to be turned into a high speed machine center.

Diamond-Like Carbon (DLC) Coating

DLC (Diamond-Like Carbon) COATING is composed from film like characteristic of carbon and made up of amorphous structure of diamond and graphite. Hardness is Hv 4,000 and friction coefficient is 0.1 μm. Coated surface is very smooth which achieves Ra 0.02 μm and very low welding that realizes excellent surface in cutting of aluminum. DLC is suitable for cutting nonferrous metals, especially for aluminums, but not for ferrous metals.
