Dial Test Indicator Contact Point, Tungsten Carbide Ball Tip, M1.6 Thread, 2mm (0.078") Sphere, 44.5mm (1.75") Length, Wear-Resistant Replacement Probe for Precision Measuring Tools

Designed for accuracy, extended service life, and interchangeability, this tungsten carbide contact point ensures your dial test indicator delivers clean, repeatable readings.The polished 2mm (0.078") carbide ball maintains its spherical geometry under heavy use, resisting wear, deformation.With a standard M1.6 threaded base, the probe installs quickly into compatible dial test indicators, eliminating downtime and restoring precise reference contact without recalibration challenges.The 44.5mm (1.75") stem length offers added clearance for accessing recessed or obstructed components—ideal for machinists, inspectors, toolmakers, and metrology technicians. Whether replacing a worn point or outfitting a backup indicator, this contact probe keeps your measurement workflow efficient and highly accurate.Product DetailsMaterial: Tungsten carbide ball + hardened steel stemThread Size: M1.6Ball Diameter: 2.0mm / 0.078"Overall Length: 44.5mm / 1.75"Wear Resistance: High—carbide resists flatteningUse With: Dial test indicators, precision measurement toolsPackaging Includes1 × Tungsten Carbide Contact Point (M1.6, 2mm, 44.5mm)

• 【Precision 2mm Carbide Ball Tip】Equipped with a finely-ground 2mm (0.078") tungsten carbide ball tip that delivers ultra-consistent point contact on flat and curved surfaces. Ideal for precision metrology, toolroom inspection, machining alignment, and calibration tasks.
• 【Durable Tungsten Carbide Construction】Built using a hardened tungsten carbide sphere and finished steel stem, offering exceptional resistance—far longer-lasting than stainless steel alternatives.
• 【Standard M1.6 Thread Compatibility】Features an industry-standard M1.6 threaded shank designed to fit most dial test indicators and lever-style gauges. Installs easily and seats securely for stable measurement readings in demanding applications.
• 【Extended 44.5mm Length for Accessibility】Measuring 44.5mm (1.75") overall length, this contact point provides extended reach into tight or obstructed measuring areas, making it a reliable option for both benchtop measurements and on-machine inspections.
• 【Reliable Replacement & Easy Handling】Works as a drop-in replacement for worn or damaged probes on test indicators. The rigid stem maintains accurate alignment without flexing, helping maintain calibration integrity and repeatable results over time.
