The ITP Disc Styli stainless steel Prob Ball is a precision probing accessory designed for measuring large inside diameters and intricate undercuts. This Type O disc ball delivers reliable contact geometry in constrained features, making it a dependable choice for metrology setups.

  • Material: Stainless steel construction for durability and corrosion resistance in shop environments.
  • Ball Diameter: 8 mm probing ball to reach and measure large internal diameters and undercuts with stable contact.
  • Thread: M5 mounting thread for secure, standard-compatible attachment to probing heads.
  • Disc Type: Spherical disc segment—designed to access recessed features with precise geometry.
  • Type / Code: Type O, part number KHM508012056, indicating the specific disc-stylus configuration.
  • Applications: Ideal for measuring large internal diameters and integrated undercuts where traditional disks are insufficient.
  • Probing Direction Note: Normal disks are unsuitable for probing in the Z direction unless discs with radius end rollers are used.

This disc stylus addresses real measurement challenges: it provides a compact, robust means to contact curved internal features and undercuts without compromising accuracy. The 8 mm ball paired with a stainless steel shaft offers repeatable results, easy cleaning, and long service life in demanding manufacturing and inspection environments. When planning measurements, keep in mind the Z-direction note to ensure your setup includes the appropriate end-roller configuration if vertical probing is required.
