Choose based on your dial indicator's thread size (M2.5 here) and the required diameter (3mm here) for your specific task. Consider the range of lengths needed for probing different depths. High-speed steel ensures durability for workshop use. ### What is the difference between a dial test indicator and a plunger dial indicator? A dial test indicator uses a lever-type contact arm that swings on a pivot, ideal for edge-finding, centering work in a lathe, and tight-clearance setups; a plunger (dial) indicator measures straight-line travel along its axis. This listing is the lever/test-indicator style intended for fine comparative measurement and alignment. ### How to use suxing needle point contact points? Screw the M2.5 thread into your dial indicator, height gauge, or depth gauge. Ensure the 3mm needle point is suitable for the groove or hole you need to measure. The effective length is the part extending beyond the thread shank. ### What is the best precision measuring tool for Indian workshops? For Indian workshops, precision measuring tools like these suxing contact points are vital. They offer accuracy and durability, fitting standard dial indicators. Ensure your tools are metric-compatible, as these are, for seamless integration into your workflow. ### Can I use these contact points daily for machining? Yes, these suxing needle point contact points are made from High Speed Steels, designed for durability and frequent use in machining environments. Their robust construction ensures they can withstand daily operations for precise measurements. ### Are these contact points healthy for precision work? These are mechanical tools, not consumables, so 'healthy' doesn't apply in a biological sense. They are safe to use for their intended purpose of precision measurement when handled correctly, ensuring accurate readings without risk. ### Is precision measuring safe to use? Yes, precision measuring tools like these contact points are safe for their intended use in engineering and machining. Always handle them with care to avoid damage or injury, and ensure they are properly fitted to your measuring instrument. ### What are the benefits of needle point contact points? Needle point contact points allow for precise measurement in tight spaces, such as the bottom of grooves or holes. They are essential for edge finding and detailed inspection work where standard contact points cannot reach. ## Compliance No product-specific compliance warnings identified.
