ITP Star Styli Type W with Ruby Ball is a precision probing solution designed for machinists and metrology labs that frequently measure deep bores, undercuts, and threaded features. Its rigid star-shaped design minimizes bending over long gauging lengths, delivering reliable end-surface contact where it matters most.

• Probe family: Star stylus design that enables accurate measurement of large diameters without deflection along long gauging lengths.
• Configuration: Type W variant with no stem-direction probe, allowing measurements very close to the bottom of holes.
• Tip material: Ruby ball for durable, precise contact against metal surfaces and wear resistance.
• Measuring length: 2 mm measuring length to capture end surfaces at the correct depth.
• Thread: M5 external thread for secure mounting in standard measurement heads and fixtures.
• Body construction: Machined stem with a robust finish designed for repeated use in shop environments.
• Part number: SIM501011040 for easy ordering and traceability.
• Applications: Ideal for measuring large diameters, undercuts, and threaded features in bores and internal cavities.

With its long, rigid stem and ruby-tipped contact, this star stylus minimizes bending errors during deep or extended gauging tasks. The Type W configuration enables measurements near the hole bottom without relying on stem-direction probes, reducing repositioning and increasing inspection efficiency. The 2 mm measuring length provides precise depth-specific contact, while the M5 thread ensures quick, secure integration into existing metrology setups. This stylus is well-suited for bore tolerance verification, internal thread checks, and undercut profiling, delivering consistent, reliable data in demanding manufacturing environments.
