The ITP Straight Stylus Type A with Silicon Nitride Ball is a precision probing accessory designed for reliable everyday CMM measurements. Its rigid carbide stem and compact 40 mm reach make it ideal for technicians and metrology labs tackling a variety of standard parts, including untreated aluminum surfaces.

• Thread: M5 threaded shank for broad compatibility with common probe fixtures and extension systems.
• Overall length: 40 mm, providing a compact, versatile reach for tight measurement setups.
• Stem material: Extremely rigid carbide to maintain straightness and minimize deflection during probing.
• Ball material: Silicon nitride (ceramic) ball for superior hardness, wear resistance, and smooth contact with workpieces.
• Geometry: Straight stylus design delivers direct, consistent contact and repeatable data across scans.
• Ideal applications: Particularly effective for scanning untreated aluminum parts, helping reduce wear on the ball and improving surface data quality.
• Ball size availability: This product group offers balls from Ø1.5 mm up to Ø10.0 mm; other sizes can be requested via configurator or by email.

The combination of a rigid carbide stem and a silicon nitride ball delivers stable, repeatable measurements across a wide range of geometries. This stylus supports efficient data collection during routine inspection, calibration, and quality control tasks, while offering predictable wear and long service life. Its Type A design is well-suited for precision probing on metal and alloy surfaces, with particular advantages when working with aluminum workpieces.
