It produces M8 x 1.25 threads to a 4H class of fit, with a bottoming chamfer that allows threading close to the bottom of a blind hole. Built from high-speed steel with a bright, uncoated finish, this tap measures 4 inches overall length and carries a 1.125-inch thread length, making it well-suited for reaching into recessed or deep-pocket work that standard-length taps cannot access.\u003c\/p\u003e\n\u003cp\u003eThis extension tap is used in metalworking applications where reach is a constraint, such as machining fixtures, assemblies with deep bosses, or components requiring threads near a hole bottom. The bottoming chamfer makes it appropriate for blind-hole work in production and job-shop environments. It is installed by machinists and tool-and-die trades working with M8 x 1.25 metric coarse thread specifications. Right-hand thread direction and right-hand flute direction are standard for conventional tap wrench or machine tapping operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design produces threads without chips, reducing the risk of chip contamination in blind holes\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer allows threading to within a minimal distance of the hole bottom\u003c\/li\u003e\n  \u003cli\u003eExtended 4-inch overall length provides reach into deep pockets and recessed features\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction offers durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e4H class of fit meets standard metric tolerance requirements for M8 x 1.25 threads\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish with 0.318-inch shank diameter and 0.238-inch square size for standard tap holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct application tap for M8 x 1.25 metric coarse thread forming operations; fits tap holders and extension tap wrenches accepting a 0.318-inch shank diameter with a 0.238-inch square drive.

Ensure the tapping machine or tap wrench is properly aligned to the hole axis before applying feed pressure. Power down and secure the workpiece in the machine before tool changes. Follow applicable shop safety practices and manufacturer recommendations for spindle speed when using in machine tapping applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8 x 1.25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 1.25 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 4H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.238 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduced Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: BXEXT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: BALAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 18595-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":51973371756850,"sku":"18595-010","price":109.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e805f3cc736fa43dedf2553168bbac94.jpg?v=1789973062","url":"https:\/\/voomisupply.com\/products\/balax-18595-010-thread-forming-extension-tap-m8-x-1-25","provider":"Voomi Supply","version":"1.0","type":"link"}
