ITP Disc Styli KIM203018004 is a stainless steel disc stylus with an M2 thread and an 18 mm contact ball, designed for precision CMM probing of internal features and undercuts. It’s aimed at technicians and engineers who need reliable access to large inside diameters and recessed geometries.

• Ball Diameter: 18 mm contact ball crafted for robust, repeatable contact with internal features and undercuts.
• Thread: M2 thread for secure, compatible mounting to standard CMM styli and accessories.
• Disc Material: Stainless steel construction providing durability and corrosion resistance in workshop environments.
• Type: Type M disc stylus, optimized for probing internal geometries and challenging undercuts.
• Application Focus: Specifically designed to measure large inside diameters and undercuts; note that normal disks are unsuitable for probing in the Z direction (except discs with radius end rollers).

This disc stylus enables precise measurement in areas that are difficult for conventional probes, delivering repeatable results across repeated runs. Its stainless steel build supports longevity in demanding metrology workflows, while the disc geometry helps maintain stable contact in recessed or grooved features. For best outcomes, calibrate with a master sphere and use in appropriate CMM setups; if Z-direction probing is required, consider discs engineered with radius end rollers.
