Description
Product Overview
The suxing Dial Digital Indicator Contact Point is a precision‑engineered component designed for high‑performance measurement applications. Constructed from a ruby tip, the contact point delivers wear resistance many times greater than conventional carbide tips, while its non‑conductive nature ensures safe operation on electrical discharge machines. The ruby ball measures 2 mm in diameter and is mounted on an M2.5 metric thread, providing a secure and repeatable connection to a wide range of dial indicators, test indicators, and depth gauges.
Each set includes five interchangeable stems—L10, L20, L30, L40, and L50—covering a range of effective lengths to suit diverse probing depths. The stems are knurled for easy handling, and the thread shank does not include the knurling portion, allowing users to select the exact length required for their measurement task. The overall design emphasizes stability, accuracy, and durability, making it a reliable choice for both routine shop floor inspections and critical laboratory calibrations.
Technical specifications include a ruby tip diameter of 0.0787 in (2 mm), a metric M2.5 thread, and a total weight of approximately 10 grams (0.353 oz). The product is manufactured by suxing and carries the model number RUBY‑CP‑2‑2018. It is listed under the Industrial & Scientific category, specifically within the Dimensional Measurement sub‑category for Dial Indicators.
Designed for compatibility with a broad spectrum of measurement tools, this contact point set enables users to quickly switch between different probe lengths without the need for additional adapters. The high‑quality ruby material resists deformation and maintains its geometry even after extensive use, ensuring consistent measurement results over the product’s lifespan.

Usage
Professionals in manufacturing, aerospace, automotive, and research laboratories rely on the suxing ruby contact point for precise depth measurement and surface profiling. Its non‑conductive ruby tip makes it safe for use on electrically charged workpieces, reducing the risk of accidental short circuits during inspection of machined components, gear teeth, and intricate cavities.
The interchangeable stems allow technicians to adapt quickly to varying measurement scenarios, such as probing the bottom of narrow grooves, deep holes, or recessed features where standard probes cannot reach. The M2.5 thread ensures a tight fit on compatible dial indicators, eliminating play and enhancing repeatability. Users can employ the set in both manual and automated measurement systems, including CNC‑controlled test rigs and handheld inspection devices.
Because the ruby tip is chemically inert, it can be used in environments with lubricants, coolants, or other fluids without degradation. This makes the product suitable for on‑site field inspections as well as controlled laboratory conditions. The set’s lightweight construction also contributes to operator comfort during extended measurement sessions.

FAQ
What is the advantage of a ruby tip over a carbide tip?
Ruby is significantly harder than carbide, which means it resists wear and deformation even after thousands of measurement cycles. This durability translates to longer intervals between replacements and more consistent measurement accuracy.
Can the contact point be used on electrical discharge machines?
Yes. The ruby tip is non‑conductive, so it does not create a short circuit when contacting electrically charged surfaces, making it safe for use on EDMs and similar equipment.
How do I select the correct stem length for my application?
Choose the stem whose effective length matches the depth you need to measure. The set includes L10, L20, L30, L40, and L50 stems, covering a range from 10 mm to 50 mm, allowing you to select the most appropriate length without excess overhang.
Is the product compatible with all dial indicators?
The M2.5 metric thread is a common standard for many dial indicators and test gauges. As long as your instrument accepts an M2.5 threaded probe, the suxing contact point will fit securely.
What warranty does suxing provide?
suxing offers a one‑year limited warranty covering manufacturing defects. If you encounter any issues related to material or workmanship, contact our support team for a replacement or repair.
