Ground to an M8 x 1.25 metric coarse thread form with a 5H class of fit, this tap produces the oversized internal thread that a wire insert requires for proper seating. The four-flute, high-speed steel construction delivers clean chip evacuation and edge retention across repeated use. The bottoming chamfer allows threading close to the bottom of blind holes, making it a practical choice for tight-clearance applications on production lines and field repair work alike. Licensed machinists, millwrights, and maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis tap is suited for thread repair and new thread installation in aluminum, magnesium, mild steel, and stainless steel workpieces. It is commonly used in automotive, aerospace, and general industrial maintenance settings where damaged or stripped metric threads must be restored to full-strength condition using HELI-COIL inserts. The bottoming chamfer design makes it especially useful in blind-hole applications where a taper or plug chamfer would leave insufficient full threads near the base of the bore.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM8 x 1.25 metric coarse thread form with 5H class of fit for HELI-COIL insert installation\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer enables threading to the base of blind holes\u003c\/li\u003e\n\u003cli\u003eFour flutes for efficient chip removal and consistent thread form\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across aluminum, magnesium, mild steel, and stainless steel\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 74.61 mm supports use in confined workspaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with HELI-COIL wire thread insert systems requiring an M8 x 1.25 STI tap.

Secure the workpiece firmly before tapping and use an appropriate cutting fluid for the base material being threaded. Apply steady, even pressure and back off periodically to break chips, particularly in stainless steel or deep blind holes. Follow the insert manufacturer's bore preparation specifications for drill size and depth before tapping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eClass of Fit\u003c\/strong\u003e: 5H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 31.75 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 74.61 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9.68 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 11.11 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 7.26 mm\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\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Magnesium, Mild Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HELI-COIL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2093-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51981486817586,"sku":"2093-8","price":39.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0c277b1d2f8f79ca75d1245d0efcf5e.jpg?v=1789982387","url":"https:\/\/voomisupply.com\/products\/heli-coil-2093-8-hand-sti-tap-m8-x-1-25-metric-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
