"Hi, I'm the Tipster, your personal guide to tips, short cuts and quick references. Look to me for advice and creative applications throughout the new "Styli & Accessories" catalog."
Standard Ruby Ball Styli
Long shank, standard ruby ball styli at work Visit Shoppwm.com for a complete selection of ruby ball styli.
Disc Styli
Select disc styli for notches and grooves. Use a lightweight extension and a knuckle for difficult to access bores.
Star Styli
PWM star styli are available with standard fixed arms, or create your own custom design with a star adapter and any combination of styli. Add a knuckle adapter for angled access. Star styli are also great for bores with undercuts and ideal for fixed position probe heads.
Pointer Styli
Popular inspection applications for point styli are points in surface measurements, scribe lines and thread root depth. Ideal for reducing vector errors and when taking points manually. Choose PWM carbide point designs for rugged, prolonged use. Check for wear and replace often for best results.
Cylinder (Sheet Metal) Styli
Cylinder styli are designed for sheet metal edge and surface measurement. Cylindrical ceramic or sapphire styli are the ultimate sheet metal styli. Great for measuring sheet metal cut-outs. Use the non-magenetic cylindrical shank on edges and the spherical tip for surface measurement. Select opaque ceramic or clear sapphire for best visibility - both are easy to qualify and nearly indestructible.
Hollow Ceramic Spheres
Lightweight, non-magnetic hollow ceramic spheres are great for large, deep bores.
Stylus Extensions
Lightweight extensions allow longer probe access on high speed CMMs and increase the life of probe heads. Choose ceramic for light weight and stable performance - carbon fiber saves even more weight, but is not as stable.
Pin Styli
Pin styli are a great alternative to custom probes - all pin styli can be combined with adapters and holders to create custom configurations specific to your needs - and they can be reconfigured later.
Stylus Adapters
Adapters come in many different types: rotary and knuckle adapters save you the time of repositioning your probe head - crossover adapters convert styli for use on systems designed for other threads - star adapters allow you make your own star configurations with any combination of styli.
Stylus Tools
Extend the life of your probes and components by always using the proper tools for installation
Hex key tools designed for tightening set screws |
Pin key for tightening stylus and accessory assemblies |
Philips head for tightening set screws and accessories |
Probe spanner for tightening extensions into probes. |
Accessories for Electronic Height Gages
Purchase a shaft, a pin stylus holder and an M2 stylus holder and build a complete set for any measuring need. Just add styli - be creative and add knuckles, adapters or other accessories.
Shafts are compatible with Mahr, Mitutoyo, Tesa, Trimos, Vertex and Wenzel electronic height gages. Visit Shoppwm.com for a complete selection of height gage accessories.
Reference Spheres
PWM Reference Spheres are available in several configurations: straight or angled, in ceramic or steel and several ball diameters.
Angled Reference Sphere |
Straight Reference Sphere |
 Reference sphere with protective sleeve |
 Reference sphere with interchangeable balls |
Standard and magnetic base plate designs provide modularity and versatility when mounting reference spheres.
Reference spheres with magnetic bases can be attached to tubular parts, to base plates, to the side of a part or anywhere, in any orientation the magenetic base will hold. Visit Shoppwm.com for more reference spheres, base plates, probe heads and accessories.
Probe Heads and Accessories
Be creative and add probe extensions, stylus extensions, knuckles, adapters and styli to design a configuration that meets your requirements.
Centerline Locators
Select the thread where you need to measure, screw in a Center-Line Locator and measure the outside or inside diameters for coordinates.
PWM's diverse stylus and accessory designs and materials maximize strength, working length and accessibility according to your requirements. See our technical data for more information.
