Manufactured from solid carbide, this contact point delivers the hardness and wear resistance required for repeated surface contact in production and inspection environments. The ball-style tip measures 1.8 mm in diameter with a contact point length of 7.3 mm, and it threads onto the gage spindle via an M2.5 x 0.45 thread. Metrologists, quality technicians, and machinist-level inspectors install this type of contact point when performing dimensional checks that require consistent, repeatable contact geometry.\u003c\/p\u003e\n\u003cp\u003eThis contact point is suited for use in both shop-floor and laboratory inspection settings where drop-style dial gages are employed. It is compatible with AGD Group 1, 2, 3, and 4 dial gages. Typical applications include surface flatness checks, bore measurement setups, and comparative dimensional inspection where a replaceable ball-tip contact point is needed to maintain gage accuracy over time.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for high wear resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eBall contact style provides consistent point contact on varied surface geometries\u003c\/li\u003e\n  \u003cli\u003e1.8 mm ball diameter suits fine-pitch and detail measurement work\u003c\/li\u003e\n  \u003cli\u003e7.3 mm contact point length compatible with standard gage spindle geometry\u003c\/li\u003e\n  \u003cli\u003eM2.5 x 0.45 thread for direct spindle attachment without adapters on compatible gages\u003c\/li\u003e\n  \u003cli\u003eDial gages with this contact point are suitable for standard mounting configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with AGD Group 1, 2, 3, and 4 drop-style dial gages requiring an M2.5 x 0.45 threaded ball contact point.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eContact point replacement is typically performed by quality technicians or toolroom personnel. Before replacing the contact point, ensure the dial gage is removed from any active fixture or comparator stand to prevent accidental spindle damage. Thread the contact point onto the spindle by hand first, then snug with the appropriate spanner or flat wrench, taking care not to overtighten and strip the M2.5 thread. Verify gage calibration after any contact point change per your facility inspection procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Style\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 1.8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 7.3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2.5 x 0.45\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Gage Groups\u003c\/strong\u003e: AGD 1, 2, 3, 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 101122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51559665664306,"sku":"101122","price":38.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80fb25af237ab4e414e2d1b8fc12a0b0.jpg?v=1786437618","url":"https:\/\/voomisupply.com\/products\/mitutoyo-101122-drop-indicator-ball-contact-point","provider":"Voomi Supply","version":"1.0","type":"link"}
