Probe Styli

Our most general purpose probe styli, these Renishaw styli are used with both touch-trigger and scanning probes. When these styli touch your workpiece, they trigger your probe to send a signal and measure geometric features. The ball end is made of ruby, which is second only to diamond in hardness, so it won’t lose its shape or wear over time. It’s completely round and smooth to avoid touching your workpiece at more than one precise point, preventing inaccurate measurements. However, these probe styli don’t work well with aluminum or cast iron surfaces. Aluminum can rub off onto the ruby, and cast iron and ruby are prone to scratching each other during scanning jobs.

As a rule of thumb, you should choose a stylus with the shortest length and largest ball-end diameter that works for your application. If a stylus is too long, it’s more likely to move farther than it should, reducing measurement accuracy. Larger ball ends reduce the possibility that the stem will accidentally touch your workpiece and interfere with the reading.

Ruby Ball-End Styli

M2 Mounting Thread and M3 Mounting Thread—Styli with M2 or M3 threads are often used in coordinate measuring machines (CMMs).

M4 Mounting Thread—Styli with M4 threads are often used on CNC machine tool probes.

Tungsten Carbide Stem—Tungsten carbide stems are the stiffest and least likely to flex. Tungsten carbide can slightly expand in changing temperatures, so if you need precise measurements, use these styli in temperature-controlled environments.

Ceramic Stem—Ceramic stems shatter in a collision instead of bending, minimizing impact to your probe and workpiece.

Carbon Fiber Stem—Carbon fiber stems are the most lightweight option, so they’re often found on longer styli.

Ruby Ball/Star-End Styli


4 Styli	5 Styli

Ball/star styli combine up to 5 styli in one, so you can reach more of your workpiece at once. This means you won’t have to swap out styli as many times during a job. They are commonly used to inspect bores, shoulders, and grooves.

M2 Mounting Thread and M3 Mounting Thread—Styli with M2 or M3 threads are often used in coordinate measuring machines (CMMs).

Probe Styli for Thin Materials

Measure holes and edges on sheet metal and other thin materials. The straight edges on these cylindrical styli maintain stable contact with thin materials better than the curved edges on a ball styli. However, they’re not as precise as ball styli. When they touch a workpiece, they trigger your coordinate measuring machine (CMM) probe to send a signal and measure geometric features. They’re often used with touch-trigger probes.

As a rule of thumb, you should use a stylus with the shortest length that works for your application. If a stylus is too long, it’s more likely to move farther than it should, reducing measurement accuracy.

Ruby Cylindrical-End Styli

Round Tip

Ruby ends are the most common because of how smooth, hard, and durable they are. Ruby is second in hardness only to diamond, so these styli won’t wear or lose their shape, which could lead to measurement errors. However, ruby doesn’t work well with aluminum or cast iron surfaces. Aluminum can rub off onto the ruby, and cast iron and ruby are prone to scratching each other during scanning jobs.

Round Tip—Probe styli with a round tip allow you to probe with the stylus end as if it were a ball stylus. The round end avoids touching your workpiece at more than one precise point, so they can detect small variations in flatness.

Panel-Mount Light-Touch Limit Switches

Our most sensitive limit switches, these switches actuate with the slightest push for a high degree of accuracy. They’re often used for determining manufacturing tolerances and detecting minute expansions and contractions. When an object pushes into the plunger actuator, it sends a signal to open or close a circuit. Install them in a standard panel cutout.

IP67 Enclosure Rating—IP67 rated switches are protected from temporary submersion. They’re ideal for wet locations.

Probe Styli Kits

Keep a variety of common Renishaw stylus sizes, extensions, and tools on hand. When styli touch a workpiece, they trigger your probe to send a signal and measure geometric features.

Make sure the thread size of the styli in the kit you choose fits your application.

These kits all include ruby ball styli, which can be used in a wide variety of applications, from touch-trigger to scanning probes. Ruby is second only to diamond in hardness, so the ball end won’t lose its shape or wear over time. It’s completely round and smooth to avoid touching your workpiece at more than one precise point, preventing inaccurate measurements. However, these probe styli don’t work well with aluminum or cast iron surfaces. Aluminum can rub off onto the ruby, and cast iron and ruby are prone to scratching each other during scanning jobs.

As a rule of thumb, you should use a stylus with the shortest length and largest ball-end diameter that works for your application. If a stylus is too long, it’s more likely to move farther than it should, reducing measurement accuracy. Larger ball ends minimize the risk that the stem will accidentally touch your workpiece and interfere with the reading.

All kits come with stylus installation tools, which give you a handle to turn so it’s easier to thread a stylus into your probe. Slide them into the hole at the top of your probe stylus. The included stylus extensions are useful if you need to reach deep or difficult-to-access areas.

EWL (effective working length) is measured from the beginning of the stem to the center of the ball or disc end.

M2 Mounting Thread and M3 Mounting Thread—Styli with M2 or M3 threads are often used in coordinate measuring machines (CMMs).

M4 Mounting Thread—Styli with M4 threads are often used on CNC machine tool probes.

Two 12 mm Lg. Break Stems—Break stems are designed to snap if your probe applies too much pressure on a workpiece, shielding the probe from damage.

One 35 mm Dia. × 5 mm Thick. High-Carbon Steel Disc Stylus—Disc styli fit in undercuts and grooves within bores that are too narrow for ball styli. However, because the stylus end is flat, they can’t measure in as many directions as ball styli. Use them with both touch-trigger and scanning probes.

Coating-Thickness Gauge Inspection Kits

With three included probes, the gauge in these kits goes beyond a typical check for coating thickness. It also measures surface profile and environmental conditions, such as temperature. Kits include everything you need for thorough tests whether you’re inspecting a surface that’s painted, powdered, or plated. Just swap out probes to measure what you need. Use the plate and shims to practice measurements and ensure the probe is working properly. The glass plate and metal shims work with the surface profile probe. The plastic shims work with the coating thickness probe. Easy to use, the gauge’s touch screen guides you through measurements step-by-step.

Switch between scan modes for full control over how you measure, from single-point tests to continuous readings. You can even find stats and create presets for repeated measurements. For long-term tracking, the gauge stores up to 250,000 results from multiple probes in up to 1,000 batches. See trends in real time with live graphing. To help you comply with ISO, ASTM, SSPC-PA, and IMO coating standards, set criteria for go/no-go tests.

Thanks to a compatible app, you can add notes and images to readings or make reports on the go. For exporting into programs such as Excel or making multimedia reports in templates, use the included software.

Choose kits based on coating and surface types.

Built-In Probe—A built-in probe lets you use the gauge one-handed—no extended probe to maneuver.

Removable Probe with 3 ft. Cable—A removable probe means you can measure underwater and up to 3 ft. away. The waterproof probes are at the end of sealed cable, so you can reach surfaces without submerging the gauge.

For Nonconductive Coatings—Kits with probes for both nonconductive and nonmagnetic coatings include a thickness probe that automatically identifies the coating and surface material.

For 0 mil to 250 mil Thick Coating—Kits with probes for 0-250 mil coating thickness are ideal for testing epoxies, flame-retardant finishes, and other thick coatings.
