Description
ITP Disc Styli are precision spherical discs designed for measuring large internal diameters and integrated undercuts. Made from stainless steel with an M5 thread and a 15 mm ball, this Type N probe delivers reliable, repeatable results in demanding metrology tasks.
- Ball Diameter: 15 mm
- Thread Size: M5
- Material: Stainless steel
- Probe Type: Spherical disc (Type N)
- Intended Use: Measurement of large inside diameters and undercuts
- Z-Direction Note: Normal disks are unsuitable for probing in the Z direction unless using radius-end roller variants
These discs enable precise internal measurements in bores, sleeves, and cavities where accessing the interior surface is challenging. The 15 mm ball provides stable contact geometry for accurate radius and diameter readings, while the M5 thread allows quick, secure mounting to standard stylus holders. Stainless construction ensures durability and corrosion resistance in shop environments, helping maintain measurement integrity over time. This Type N configuration is well-suited for general-purpose internal-diameter inspection in manufacturing, tooling, and quality control workflows.
