Description
The ITP Straight Styli Type B with a silicon nitride ball delivers dependable, high-precision contact for everyday metrology tasks. Designed for routine probing and surface measurements, it pairs a rigid tungsten carbide stem with a compact M5 mounting thread for reliable compatibility.
- Thread: M5 mounting thread for secure, quick attachment to compatible probes.
- Overall Length: 25 mm total length offers a compact probing point in tight spaces.
- Stem Material: Tungsten carbide stem provides exceptional stiffness and wear resistance for consistent measurements.
- Ball Material: Silicon nitride ball delivers smooth contact and reduced wear, especially effective when scanning aluminum surfaces.
- Design: Straight stylus with the option for single or multi-stepped stems to tailor probing profiles to your workflow.
- Ball Size Options: Ball diameters range from Ø1.0 mm to Ø1.5 mm within this product group; other sizes can be requested via the configurator or by email.
This stylus enhances measurement reliability by minimizing deflection through a stiff carbide stem, while the silicon nitride ball minimizes wear on both the tip and the workpiece. The 25 mm length keeps the probing point accessible in cramped fixtures, and the M5 thread ensures compatibility with a wide range of probes. Ideal for routine CMM probing, surface scanning, and gauging on aluminum parts, this Type B straight stylus is built to perform consistently in demanding shop environments.
