The block is set at a fixed 10-degree angle and measures 3 inches in overall length. With a Rockwell C hardness rating of 55 HRC, the working surfaces resist wear and maintain dimensional stability under repeated use. Accuracy is rated to 20 arc-seconds, making this block suitable for close-tolerance setups on surface plates, magnetic chucks, and sine fixture assemblies. Machinists, tool-and-die makers, and quality control technicians are the primary users of this type of precision workholding accessory.\u003c\/p\u003e\n\u003cp\u003eAngle blocks at a 10-degree angle are commonly used in machine shops and inspection rooms where workpieces must be held or measured at a consistent, repeatable incline. Typical applications include grinding angled surfaces, setting up milling fixtures, and verifying angular dimensions during final inspection. The 3-inch length provides adequate contact surface for small to medium workpieces without introducing excessive overhang or setup instability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFixed 10-degree angle for repeatable angular setups\u003c\/li\u003e\n  \u003cli\u003e55 HRC hardness for wear resistance and long service life\u003c\/li\u003e\n  \u003cli\u003e3-inch overall length suits small to medium workpiece setups\u003c\/li\u003e\n  \u003cli\u003eAccuracy rated to 20 arc-seconds for close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling on a surface plate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard precision angle block for use with surface plates, magnetic chucks, and sine bar fixture setups common in general machining and inspection environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAngle blocks are positioned and secured by a machinist or metrology technician — no power source or trade license is required for use. Clean all mating surfaces before placing the block to prevent debris from introducing angular error. When used on a magnetic chuck, verify the block is fully seated and the chuck is energized before initiating any grinding pass. Handle hardened tooling carefully to avoid chipping the reference surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 55 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 20 arc-seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 630-4310\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698103877938,"sku":"630-4310","price":31.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8ef1a37787ae7c0cc226d1121e006d4.jpg?v=1788357744","url":"https:\/\/voomisupply.com\/products\/value-collection-630-4310-angle-block-10-degree-55-hrc","provider":"Voomi Supply","version":"1.0","type":"link"}
