ITP Straight Styli Type A with a ruby ball delivers a reliable, budget-friendly option for daily tactile measurement tasks. Built for routine use in labs and on the shop floor, this stylus pairs a rigid stainless steel stem with a precision ruby ball to deliver consistent contact readings on CMMs and other metrology equipment.

• M4 Thread: Standard mounting thread for quick, secure installation and easy interchangeability with compatible probes and fixtures.
• Overall Length: 22.5 mm total length, delivering a compact reach ideal for probing small features and tight geometries.
• Ball Material: Ruby ball selected for excellent wear resistance and stable hardness in tactile measurement, reducing wear on both the stylus and the test surface.
• Ball Diameter Options: Available with ruby balls from Ø1.0 mm up to Ø8.0 mm to suit a range of probing applications (choose the size to match feature contact requirements).
• Stem Material: Stainless steel construction provides rigidity, helping maintain measurement fidelity under typical handling and use.
• Intended Use: Designed for daily standard use in tactile 3D measurement workflows, including CMM probing, fixture verification, and routine part inspection.

The combination of a stiff stainless steel stem and a ruby contact point minimizes deflection and wear during repeated touches, supporting repeatable measurements and longer tool life. Its compact 22.5 mm length and M4 mounting thread offer versatile compatibility with common metrology setups, enabling quick probe changes without compromising accuracy. This makes it an economical choice for teams performing everyday measurements where reliability and ease of use matter most.
