Description
The ITP Straight Stylus Type A with Silicon Nitride Ball is a reliable, straight-contact probing solution designed for everyday metrology tasks. With an M5 mounting thread and a compact 58 mm overall length, it delivers stable, repeatable scans in standard CMM workflows, especially when inspecting aluminum parts.
- Thread: M5 thread for secure mounting on compatible stylus holders
- Overall Length: 58 mm to provide good reach without sacrificing control
- Stem Material: Extremely rigid carbide to minimize deflection during probing
- Ball End: Silicon nitride ball offers wear resistance and compatibility with challenging surfaces
- Geometry: Straight stylus design for predictable contact and scanning behavior
This stylus is particularly well-suited for scanning untreated aluminum parts, where the silicon nitride ball helps reduce wear and maintain consistent contact. Its durable carbide stem maintains dimensional stability under probing forces, enabling reliable measurements across repetitive cycles. Ideal for labs and production environments performing routine dimension checks, feature inspections, and surface analysis with standard measurement setups.
