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 range 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 impressive improvements in tool life and consistency. See Coatings for more info.
A high speed machining centre is required to properly utilise the small diameter tools. At Livetools, we supply Air Turbine Tools, 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 centres.

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 aluminium. DLC is suitable for cutting nonferrous metals, especially for aluminiums, but not for ferrous metals.
