Check out our M4 threaded styli with tungsten carbide stems for CMM scanning and machine tool probing applications. Tungsten carbide stems offer the best stiffness to weight ratio, and provides the least amount of deflection, especially for longer range length styli with small diameter stems; which is invaluable particularly in CMM scanning operations.
