11.8mm Precision Measuring Insert Ball Tip 0.4mm, Solid Carbide - Käfer Messuhrenfabrik GmbH & Co. KG

Take advantage of the combination of carbide construction, a Ø 0.4 mm precision ball tip and secure M1.6 threading to ensure reliable contact measurements and reduced inspection downtime; order the insert directly via Metav Werkzeuge or contact our advisors for compatibility details.

Measuring insert Ø 0.4 mm, ball tip – carbide, M1.6 thread (Käfer)

The measuring insert Ø 0.4 mm (ball), carbide is a precision probe tip designed for dial and feeler-type measuring instruments, compatible with Käfer models K30, K31, K32 and K46.

• Carbide ball tip Ø 0.4 mm
• Length 11.8 mm for extended reach
• M1.6 threaded connection for secure fit
• Compatible with Käfer K30–K46 series

Precise contact for extremely fine measurements

The carbide ball tip with a diameter of Ø 0.4 mm provides a very small contact area, which helps to reduce measurement uncertainty and improves repeatability in fine inspection tasks. As a gauge insert, the hardened contact surface resists deformation under typical probe pressures, maintaining geometric integrity over many measurements. This minimises the need for frequent recalibration and supports consistent results when inspecting small features or tight tolerances.

Robust attachment and shop-floor durability

A tip length of 11.8 mm offers enough reach for recessed features while keeping deflection low. The M1.6 thread delivers a secure mechanical connection to compatible holders and measuring heads, preserving alignment during repeated cycles. Constructed from carbide, the insert combines high wear resistance with dimensional stability, which is especially beneficial in production environments where frequent contact events can accelerate wear on softer materials.

Compatibility that keeps inspection running

Designed for quick integration with Käfer measuring instruments (models K30, K31, K32, K46), this measuring tip reduces tooling changes and potential downtime. The standardised thread and compact ball form mean replacement inserts restore original probe geometry with minimal adjustment. For workshops and quality departments seeking efficient inventory management, the standard form factor and material choice support predictable service intervals and straightforward stocking.

FAQ

What is the ball diameter and why does it matter?
The measuring insert has a Ø 0.4 mm ball; a smaller diameter reduces contact area and is advantageous for measuring fine features and tight radii with improved repeatability.

Is the insert compatible with my Käfer dial indicator?
Compatibility is specified for Käfer models K30, K31, K32 and K46; the measuring insert mounts via an M1.6 thread to ensure correct fit on those instruments.

What material is used and how does it affect performance?
The tip is made from carbide, which offers high wear resistance and dimensional stability, extending service life under frequent contact conditions.

Can this insert be used for routine shop-floor inspection?
Yes, the durable construction and standard thread make the insert suitable for regular use in production inspection and lab environments where consistent probe geometry is required.
