Description
The ITP Disc Styli stainless steel Prob Ball is a precision probing accessory designed for metrology professionals who measure large inside diameters and undercuts. It features a robust M5-threaded mount and a 15 mm spherical probe ball for reliable, repeatable contact in demanding setups.
- Material: Stainless steel construction for durability, corrosion resistance, and stable measurements in shop environments.
- Ball diameter: 15 mm spherical probe ball designed to access larger bores while minimizing edge interference.
- Thread: M5 thread for secure, standard mounting to probe stems and accessories.
- Type: Type M configuration optimized for spherical disc probes used in bore and undercut measurements.
- Application: Ideal for measuring large inside diameters and integrated undercuts where access is geometrically restricted.
- Part number: KIM515007040
- Z-direction note: Normal disks are unsuitable for probing in the Z direction unless the design includes radius end rollers (check compatibility for vertical probing).
Benefits: This disc styli design combines a sturdy stainless body with a precisely sized 15 mm ball to deliver accurate contact in challenging bore geometries. The M5 mounting thread enables quick integration with existing probing heads, reducing setup time and improving repeatability across multiple measurements. Use this accessory to reliably inspect large bores and recessed features in components such as housings, sleeves, or turbine parts, where traditional disks struggle to reach or maintain stable contact. By choosing a Type M disc styli, you gain a specialized tool that supports consistent, high-accuracy measurements in metrology workflows.
