Accurate groove measurement where space is limited

The insert converts a standard caliper into a dedicated groove probe, allowing precise checks of recesses without the need for larger, more complex fixtures. With a defined groove width 1.2 mm and a max groove depth 13 mm, the tip delivers repeatable contact geometry that reduces measurement scatter and improves comparability between readings. The geometry is optimised to sit securely in the groove flank so that a single, controlled contact produces a verifiable reading rather than a variable result caused by inconsistent probing angles.

Secure mounting and repeatable handling for fast inspection cycles

A Ø5 mm shank ensures a tight, wobble‑free connection to compatible caliper adapters, while the 70 mm length gives enough reach for most assemblies without sacrificing stiffness. The low weight (0.05 kg) makes handling light and reduces the effect of operator force during manual measurement. Together these attributes support short set‑up times and repeatable positioning, which is particularly valuable for batch inspections and spot checks on the production line.

Practical use cases and workshop advantages

Designed as an accessory for inspection and quality control, the probe is suitable for groove verification in components and assemblies where access is restricted. The compact measuring tip is ideal for checking grooves in housings, bearing seats and small machined components. As an accessory class product within the metrology toolkit, it complements standard calipers and adapters to extend measuring capability without the need for dedicated groove gauges, helping to keep the tool inventory efficient and adaptable.

FAQ

What groove dimensions can this insert measure?
The insert is designed for internal grooves from 40 mm in diameter, with a maximum depth of 13 mm and a nominal groove width of 1.2 mm; these parameters define the intended measurement range for the M240.326.

Which adapters and calipers are compatible?
Compatibility is achieved via the Ø5 mm shank interface; the insert fits standard caliper adapters that accept a Ø5 mm probe shank and is intended for manual caliper-based inspection setups.

How does the insert improve repeatability compared with ad‑hoc probing?
By providing a defined contact geometry and a stable Ø5 mm connection, the probe reduces lateral play and inconsistent contact angles, leading to more repeatable readings during routine checks.

What applications are typical for this measuring tip?
Typical uses are groove inspection in housings, bearing seats and small machined components where access is limited and a compact, repeatable measuring tip is required for quality control.
