*Get your diamond-tipped styli from Probes by Rick!


Q-Mark now offers diamond-tipped styli in ball sizes ranging from 1.0 to 5.0 mm diameter.  We stock two kinds of diamond spheres: solid diamond, and diamond coated.  Solid diamond spheres are superb for probing hard or abrasive surfaces.  Diamond coated spheres are recommended for probing soft alloys, like aluminum.
