Description
The ITP Disc Styli stainless steel Prob Ball is a precision disc-style probe tip designed for metrology professionals who need to measure large internal diameters and complex undercuts with a CMM. This Type O disc stylus (KIM525011065) features a 25 mm ball diameter and an M5 mounting thread for seamless integration with standard probe fixtures.
- Material: Stainless steel base with a stainless steel ball and carbide stem for rigidity and long-term stability.
- Ball diameter: 25 mm contact ball provides a robust, wide contact area for challenging internal geometries.
- Thread: M5 mounting thread for compatibility with common probe heads and accessories.
- Type: Type O disc stylus, part of ITP's disc stylus family designed for probing undercuts and large bores.
- Application: Ideal for measuring large inside diameters and integrated undercuts where traditional disks struggle.
- Probing note: Normal disks are unsuitable for probing in the Z direction (except discs with radius end rollers), making this geometry a practical choice for specific measurement needs.
- Part number: KIM525011065
This disc stylus enables reliable probing of internal features that are otherwise difficult to access, with a robust 25 mm contact ball and a durable stainless steel construction. It is well-suited for precision inspection workflows where repeatable data is essential, helping you capture accurate measurements for quality control, process verification, and dimensional analysis across complex bores and undercuts.
