Mitutoyo Measurement Stylus Tip M1.7 with 2.00 mm Ball, Length 44.5 mm, Carbide

Replacement measurement stylus tip for Mitutoyo probes with an M1.7 thread, featuring a 2.00 mm spherical carbide contact and a total length of 44.5 mm. The stylus tip is intended for coordinate measuring machines (CMMs) and contact indicator probes where stable contact geometry and repeatable touch points are required for dimensional inspection, gauge verification and reverse engineering tasks.

Advantages

The carbide 2.00 mm ball offers wear resistance and stable contact behavior across repeated measurements. The M1.7 threaded shank provides compatibility with Mitutoyo probe systems that accept this thread size, allowing straightforward replacement and restoration of probe performance. The overall length of 44.5 mm gives a balance between access to recessed features and stiffness for accurate probing results.

Suitable for

• High-precision contact probing on CMMs
• Dimensional inspection of small features and tight tolerances
• Reverse engineering where precise surface point capture is needed
• Indicator probes and touch-trigger probes that use M1.7 threaded styli

When it may not be suitable

This stylus tip is not intended for non-contact measurement methods such as optical scanners or laser profilers. Carbide contact balls can be harder and less forgiving than ruby in delicate or soft-surfaced measurement tasks, so they may not be ideal where minimal surface marking is required. Additionally, use on probe systems that require a different thread size or mounting geometry will not be compatible.

Key specifications

• Contact ball diameter: 2.00 mm (spherical)
• Contact material: carbide (hard, wear-resistant)
• Shank thread size: M1.7
• Overall length: 44.5 mm
• Intended use: contact probing for CMMs and indicator probes

How to use

Install the stylus tip by screwing the M1.7 threaded shank into the compatible probe holder or extension until secure, taking care not to overtighten. Calibrate the probe with the new stylus attached according to the probe and CMM manufacturer instructions to ensure accurate offsets and correct touch point compensation. Use standard probing strategies appropriate for the workpiece material and geometry, and verify repeatability on a known artefact after installation.

What to consider before purchase

• Verify that your probe or holder accepts an M1.7 threaded stylus.
• Confirm that a 2.00 mm carbide contact ball is suitable for your workpiece finish and hardness.
• Ensure the 44.5 mm overall length gives the required reach and stiffness for your application.

Usage recommendations

Regularly inspect the carbide ball for wear and surface damage; replace the stylus tip if roundness or surface condition deteriorates. Clean the thread and contact ball before mounting and follow the probe manufacturer’s calibration procedure after each replacement to maintain measurement accuracy.
