M240.325 Internal-groove measuring insert for caliper adapters — 1.2 mm width, 1.4 mm depth (Metav IndustryLine)

A M240.325 internal-groove measuring insert designed for use with caliper adapters, suitable for internal grooves from 15 mm with a maximum depth of 1.4 mm and a width of 1.2 mm.

• Precision-ground insert for internal grooves
• Designed for grooves from 15 mm diameter
• Max depth 1.4 mm, width 1.2 mm

Faster, repeatable internal-groove inspections

The measuring insert is engineered to speed up routine checks while keeping results consistent. Fitted on a caliper adapter, the Ø5 mm shank secures the insert in the holder so measurements are taken with minimal play, improving repeatability and lowering measurement scatter. The clearly defined 1.4 mm depth limit and 1.2 mm width make it straightforward to confirm compliance for narrow grooves, which reduces the need for rework and shortens inspection cycles on the shop floor.

Designed for tight grooves and reliable fit

A slim profile and precisely machined contact faces ensure the insert reaches confined internal features without damaging edges. The geometry is optimised for internal keyways and narrow channels starting at 15 mm, providing a firm seating against the groove flanks and improving reading stability. Where speed of inspection matters, the insert’s design permits quick engagement and withdrawal from the groove, enabling efficient quality control on assemblies and components.

Workshop integration that keeps production moving

As an accessory for caliper adapters, this insert integrates directly into existing digital or analogue calipers equipped with compatible holders, avoiding the need for a separate specialised gauge. Lightweight at approximately 0.05 kg and with a compact 70 mm overall length, it is easy to store and swap between tasks. The insert supports a pragmatic inspection workflow: defined limits, secure mounting and rapid handling translate into lower inspection times and more predictable throughput for repetitive measurements.

FAQ

What groove sizes can be measured with this insert?
The insert is intended for internal grooves starting at 15 mm diameter and is specified for a maximum depth of 1.4 mm and width of 1.2 mm; this makes it suitable for narrow keyways and similar features.

Is the insert compatible with digital and analogue calipers?
Yes. The M240.325 mounts via a Ø5 mm shank into standard caliper adapters, so it can be used with both digital and analogue calipers that accept the compatible holder.

How does the insert improve measurement repeatability?
Secure mounting and precise contact geometry reduce movement and operator influence, resulting in more consistent readings and improved repeatability during series inspections.

Can the insert be used for external measurements or other tasks?
This insert is specifically designed for internal groove inspection and is supplied for use with caliper adapters; external measurements require suitably configured jaws or other dedicated inserts.

What is the weight and size of the insert for handling and storage?
The insert weighs approximately 0.05 kg and measures 70 mm in length, offering a compact, lightweight solution that is simple to handle in the workshop.
