INSIZE measuring tip M2.5, hardened carbide, radius 1.5 mm, length 20 mm

INSIZE measuring tip M2.5, hardened carbide, radius 1.5 mm, length 20 mm is a replacement stylus designed for contact measurement probes, indicators and comparators. The tip features a hardened carbide spherical contact with a 1.5 mm radius and a total length of 20 mm. It is intended for applications requiring a small, wear-resistant contact point that maintains measurement accuracy on small, curved or hard surfaces.

Advantages

The hardened carbide construction provides high wear resistance and long service life compared with softer materials. A spherical radius of 1.5 mm offers consistent point contact for repeatable measurements on curved profiles and small features. The M2.5 thread size ensures compatibility with tools and probes that accept M2.5 stylus mounts. The 20 mm overall length balances reach and rigidity to reduce deflection during contact measurement.

Suitable for

• Contact probes and dial indicators with M2.5 stylus connection
• Precision comparators and gauging fixtures
• Measuring small-diameter or curved surfaces where a spherical contact is needed
• Workpieces made of hard or abrasive materials requiring wear-resistant tips

Key specifications

• Contact material: hardened carbide
• Contact geometry: spherical tip
• Sphere radius: 1.5 mm
• Thread size: M2.5
• Overall length: 20 mm

How to use

Install the measuring tip by screwing it into the M2.5 threaded socket of the probe or indicator until it is securely seated. Ensure the mating threads are clean and free of debris before installation to prevent cross-threading. After installation, verify alignment and zero the instrument according to the instrument manufacturer’s procedure. Use gentle, controlled contact when measuring to avoid shock or lateral forces that could damage the tip or affect measurement accuracy.

Usage recommendations

For reliable, long-term performance, avoid using the tip on corrosive materials without appropriate cleaning and drying. Regularly inspect the spherical contact for wear or flat spots and replace the tip if measurement repeatability degrades. Store spare tips in a protective case to prevent accidental damage to the carbide sphere.
