Description
The ITP Straight Styli - Type G with Ruby Ball delivers precise, reliable probing for tight-feature measurements. Designed for metrology and CNC setup work, it offers a rigid core and flexible mounting options to fit disc and star stylus configurations.
- Thread: M5 extended-thread design for secure mounting with compatible fixtures and probing systems.
- Overall Length: 21.8 mm total length, providing a compact profile that fits confined measurement spaces.
- Stem Material: Tungsten carbide stem for exceptional rigidity and dimensional stability across a wide range of dimensions.
- Ball Diameter: Ruby ball options from Ø0.3 mm up to Ø1.0 mm, using high-quality ruby for precise contact and long wear life.
- Mounting for Discs/Star Styli: Extended thread optimized for mounting discs and star styli; grooved and clamping discs are required for star stylus configurations.
- Dimensional Variants: The stem can be single- or multi-stepped; other dimensions are available on request via configurator or email.
This stylus is ideal for professionals performing micro-feature probing, toolmaker inspections, or CMM verification where repeatable contact and rigid support matter most. The combination of a carbide core and a ruby ball minimizes deflection under load, delivering consistent measurements across sessions. Use-case versatility includes configuring with discs for modular setups or tailoring ball size to suit tiny diameters and fine features, all while keeping a compact, robust profile in your measurement routine.
