Description
Meet the ITP Straight Styli - Type A, a precision straight stylus designed for everyday CMM measurement tasks. Built for technicians and engineers who value rigidity and reliable contact, it excels in routine probing of metal workpieces, including untreated aluminum.
- Ball material: Silicon nitride ball for wear resistance and smooth, consistent contact during scans.
- Stem material: Carbide stem delivers extreme rigidity to maintain accurate dimensions across a wide range of probe lengths.
- Thread: M3 thread for quick, secure mounting on standard stylus holders.
- Overall length: 51.5 mm, offering a balanced reach for typical fixtures and work envelopes.
- Ball size range: Part of a line offering ball sizes from Ø1.5 mm to Ø5.0 mm to suit different probing requirements.
- Intended use: Straight stylus intended for everyday standard use and reliable scanning of metallic workpieces.
This combination—rigid carbide, wear-resistant silicon nitride, and a versatile 51.5 mm length—helps produce consistent measurement data with reduced deflection and longer stylus life. The silicon nitride ball is particularly recommended when scanning untreated aluminum, where it helps achieve smooth contact and accurate readings. Compatible with a range of standard measurement setups, this Type A stylus is ideal for repeatable inspections, calibration tasks, and ongoing production-quality checks.
