Description
ITP Straight Styli Type A with Ruby Ball, M4 thread, 103 mm overall length (TKM406007100), is a precision probing stylus designed for reliable everyday measurements. With a lightweight ceramic stem and a high-quality ruby contact ball, it's ideal for metrology professionals seeking consistent, wear-resistant performance.
- Thread: M4 male thread for compatibility with standard stylus holders.
- Overall length: 103 mm from tip to thread end.
- Stem material: High-performance ceramic for low weight and high rigidity.
- Ruby ball diameter: Premium ruby contact balls available from Ø6.0 mm to Ø10.0 mm.
- Holder feature: Holder with spanner width SW5,5 for secure installation.
- Type: Type A designation in the straight stylus family.
- Customization: Other sizes can be requested via the configurator or by email.
This combination delivers precise, repeatable readings with minimal deflection during probing. The ceramic stem keeps the weight down, reducing stress on delicate parts, while the ruby ball provides a hard, wear-resistant contact surface that maintains form over many cycles. The 103 mm reach supports probing into recessed features and aligns with standard inspection workflows, and the M4 thread ensures quick, secure installation in common stylus holders. If your measurement tasks require a different ruby ball diameter or length, request a custom size through the configurator or by email to tailor the tool to your workflow.
