Built from micrograin solid carbide, it delivers superior wear resistance and edge retention compared to high-speed steel alternatives. The bright\/uncoated finish suits a wide range of work materials. With 4 flutes and a 6H class of fit tolerance, this tap produces accurate, clean internal threads. The D5 thread limit ensures proper sizing for standard metric fastener engagement. It is used by machinists, toolmakers, and production technicians working in precision manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for bottoming applications where threads must extend close to the bottom of a blind hole. The straight flute geometry works best in short-chipping materials such as cast iron, brass, bronze, and some plastics. The 4-flute configuration provides chip clearance while maintaining stability during the threading operation. It is a standard fit for CNC machining centers, knee mills, and manual tapping operations where rigid setup and controlled feed rate are maintained.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threads to be cut close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for extended tool life and edge stability\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes optimized for short-chipping work materials\u003c\/li\u003e\n  \u003cli\u003e6H class of fit for standard metric thread tolerance compliance\u003c\/li\u003e\n  \u003cli\u003eD5 thread limit for consistent fastener fit and gauge compliance\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping operations\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish with no coating buildup to affect thread geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit bottoming tap for M8x1.25 metric coarse internal threading applications in CNC and manual machining setups requiring 6H tolerance class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by a machinist or toolroom technician. Secure the workpiece fully before tapping to prevent movement and tap breakage. Use appropriate tapping fluid or cutting oil for the work material to reduce heat and extend tool life. Solid carbide taps are brittle compared to HSS  -  avoid lateral loading, misalignment, or hand-reversal techniques that could cause fracture. Follow machine feed rates appropriate for carbide tooling and verify hole depth provides sufficient clearance below the threaded zone.\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\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.719 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: REGAL CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 018812RS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"REGAL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":67910274449714,"sku":"018812RS","price":137.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe95a4bc3ec81731159dff7f78e3abdd_d2e08aa5-02c1-49c7-8a5a-58c5cc22233a.jpg?v=1791197107","url":"https:\/\/voomisupply.com\/products\/regal-cutting-tools-018812rs-m8x1-25-bottoming-tap-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
