A tungsten carbide stem provides exceptional rigidity, particularly for styli with small ball and stem diameters. Silicon nitride is a very hard and wear resistant ceramic which can be machined into very high precision spheres. It does not have the attraction to aluminium and so does not exhibit the adhesive wear seen with ruby in similar applications.Equivalent to Q-Mark part number: TM2-1020-DS.8-SN Technical tableBall diameter (mm)1Centre styliNEWL (mm)12.5Holder materialStainless steelOverall length (mm)20Stem diameter (mm)0.8Stem materialTungsten carbideThreadM2Tip materialSilicon nitride Technical documentation A-5004-2021 A-5004-2021 Technical drawing for A-5004-2021 [0B] Shopping security Recall your cart
