Features: New High Quality Made of high-quality materials for durability CMM styli for CMM machines CMM styli for CNC machines Straight styli are designed to detect simple features in direct, unobstructed contact with the surface being measured. Tungsten carbide stems provide excellent rigidity, especially for ball and stem diameter styli. Gem balls are considered the industry standard for stylus nibs. It is of the toughest materials and is suitable for most applications. Long service life and no surface wear due to abrasive materials. The ball head is light-weight, wear-resistant and stable with temperature changes. The ceramic rod is very light yet very strong and offers built-in crash protection. Non-magnetic and non-conductive properties for fine and silicon carbide surfaces and electrical discharge machining (EDM) processes. The probe has good corrosion resistance, wear resistance and light transmission.
