Item Description

Renishaw M5 Hemispherical Stylus, Ø30 mm Ceramic Styli New with 1 Year Warranty.


Hemispherical Styli

are designed for the inspection of rough surfaces and deep features, such as bores. Cermaic tips are lightweight, hardwearing and non-magnetic.

A few simple rules can be applied to maximize accuracy for most probing applications. 

Overall length

Renishaw uses a standard description of overall length, measured from the rear mounting face of the stylus to the centre of the ball. 

Effective Working Length (EWL)

This is measured from the centre of the ball to the point at which the stem will foul against the feature when measuring 'normal' to the part. 

Technical Table

Ball grade 40
Diameter (mm) 30
Overall length (mm) 24.5
Stem material Stainless steel
Thread M5
Tip material Ceramic

Rules for Choosing a Stylus

A few simple rules for stylus selection can be applied to maximize accuracy for most probing applications 

Keep Styli Short

The more the stylus bends or deflects, the lower the accuracy. Probing with the minimum stylus length for your application is the best option. 

Minimise Joints

Every time you join styli and extensions, you introduce potential bending and deflection points. Try, wherever possible, to keep to the minimum number of pieces possible for your application.

Keep the Stylus Ball as Large as Possible:

There are several reasons for this:

it maximises your ball/stem clearance, thereby reducing the chance of false triggers caused by 'shanking out' on the stylus stem, and increasing the EWL;

a larger ball allows a larger stem diameter, increasing the stiffness of the stylus;

the larger ruby ball reduces the effect of the surface finish of the component being inspected.

EWL can also be affected by assembly tolerances. For this reason Renishaw styli are assembled to exacting standards in controlled conditions.
