Description

ITP Disc Styli are precision spherical discs designed to tackle challenging internal geometries with a CMM. This stainless steel probe features a 16 mm ball and a compact M5 thread, delivering reliable, repeatable measurements in tight spaces and large bore features.

  • Ball diameter: 16 mm ball provides ample contact area for stable readings in large bores.
  • Thread: M5 mounting thread for secure, quick integration into compatible stylus assemblies.
  • Material: Stainless steel construction offers corrosion resistance and durability in shop environments.
  • Disc type: Type O spherical disc profile designed for precise contact with internal surfaces.
  • Part number: KHM516012057 for accurate catalog reference and ordering.
  • Ideal use: Optimized for measuring large inside diameters and integrated undercuts where standard disks struggle.
  • Probing note: Normal disks are unsuitable for probing in the Z direction unless the disc includes radius end rollers.

The disc styli design enables accurate, repeatable measurements of challenging internal features. The 16 mm sphere reachs into bore interiors while maintaining a stable contact, and the stainless steel body withstands repeated use in demanding environments. The M5 thread simplifies swapping into existing probe setups, while the Type O configuration provides a robust, reliable interface for high-precision data. When planning measurements, keep in mind that this disc is optimized for internal diameters and undercuts, with clear guidance on Z-direction probing to ensure you select the right configuration for your inspection tasks.
