ITP Straight Styli Type A with Silicon Nitride Ball is a high‑rigidity precision stylus designed for reliable everyday measurement tasks. Built for metrology professionals who need repeatable scans, it excels when probing a range of parts, including untreated aluminum.

• Ball material: Silicon nitride ball for excellent hardness, wear resistance, and favorable scanning on aluminum surfaces
• Stem material: Extremely rigid carbide stem to minimize deflection and improve measurement stability
• Thread: M5 thread for secure, standard mounting to compatible probe heads
• Overall length: 82.5 mm, providing ample reach for accessing recessed features
• Holder compatibility: Suitable for measuring systems that use Ø10,0 mm, Ø11,0 mm and Ø12,0 mm holders
• Ball size range (group): Part of a family offering ball diameters from Ø1,5 mm up to Ø10,0 mm to match different measurement needs

This stylus is ideal for technicians and engineers who demand consistent slam‑free contact, precise hit detection, and long‑lasting performance. The silicon nitride ball reduces wear on challenging materials, while the carbide stem maintains stiffness across a wide range of dimensions. Use cases include high‑resolution scanning of small features, checking flatness and runouts on aluminum parts, and routine CMM measurements where a dependable, long‑life stylus is essential.
