Mitutoyo probe tip M1.7×0.35, ball Ø2.00 mm, length 33.9 mm (MPN 131324)

Replacement probe tip M1.7×0.35 with a 2.00 mm spherical ball and overall length 33.9 mm, designed for Mitutoyo tactile probing systems. This probe tip provides a precisely shaped ruby/ball contact surface and standardized thread to fit compatible probe bodies used on coordinate measuring machines, probe heads and dial indicators. It is intended to deliver consistent contact geometry for accurate point probing during dimensional inspection and metrology tasks.

Advantages

The M1.7×0.35 probe tip offers a small-diameter spherical contact that reduces contact area and helps minimise form error during measurement. Its 2.00 mm ball geometry provides repeatable contact points and stable deflection characteristics, while the 33.9 mm length allows reach into confined or recessed features. Manufactured to Mitutoyo tolerances, the tip is suitable for high-precision measurement chains where consistent contact geometry is required.

Suitable for

• Tactile point probing on coordinate measuring machines (CMMs)
• Probe heads and stylus setups for inspection tasks
• Dial indicators and manual or motorised probe systems requiring M1.7×0.35 thread
• Measuring small radii, holes, grooves and surface locations where a 2.00 mm ball is appropriate

When it may not be suitable

This probe tip is intended for tactile contact measurement and may not be suitable for non-contact or optical measurement systems. Applications that require larger contact areas, heavy-duty probing, or high lateral loads may need a larger ball diameter or more robust stylus design. Do not use the tip where chemical compatibility, elevated temperatures, or abrasive environments exceed the material capabilities of a standard ruby/ball probe tip.

Key specifications

• Thread size: M1.7×0.35 (compatible with matching probe bodies)
• Ball diameter: 2.00 mm spherical contact
• Overall length: 33.9 mm
• Contact material: spherical (ruby or equivalent hard material for wear resistance)
• Intended use: tactile point probing for precision metrology

How to use

Fit the probe tip by screwing it into a compatible probe body or stylus holder with the matching M1.7×0.35 thread until it is securely seated. Verify that the assembly is correctly aligned and that the probe body’s calibration or stylus settings are updated to reflect the installed tip length and ball radius. Use gentle approach speeds and appropriate probing forces recommended for your probe system to avoid damage or measurement errors. Regularly inspect the ball surface for wear or contamination and replace the tip if the contact surface becomes damaged.

What to consider before purchase

• Ensure thread compatibility with your probe body or stylus holder (M1.7×0.35)
• Confirm that a 2.00 mm ball diameter meets your measurement accuracy and contact area requirements
• Check the overall length (33.9 mm) for reach and clearance in your application
• Verify material suitability for your operating environment (temperature, chemicals, abrasion)

Usage recommendations

For accurate and repeatable results, use the probe tip with compatible Mitutoyo probe systems and perform periodic calibration or verification runs. Maintain a clean contact surface and avoid excessive lateral forces; replace the tip when wear or deformation is observed to preserve measurement integrity.
