Built from powdered metal and coated with TiCN, it handles hardened steel, stainless steel, high-nickel alloys, titanium, and alloy steel without the rapid wear typical of standard HSS taps. With 3 flutes and a plug chamfer, it pushes chips forward ahead of the cutting action, making it well suited for through-hole tapping operations. The H2 thread limit holds tight tolerances for 3B class of fit applications. Licensed machinists, toolmakers, and maintenance technicians commonly use this tap on manual machines and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis tap is intended for production and precision threading in ferrous and high-strength materials across industrial, aerospace, and general machining environments. It threads 8-32 UNC right-hand through holes where chip evacuation is critical and tool life in tough materials is a priority. The Series 312TI designation marks it as part of OSG's TiCN-coated powdered metal spiral point line, built for applications where standard coatings fall short.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating increases surface hardness and lubricity for extended tool life in difficult materials\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction provides superior wear resistance compared to standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, keeping flutes clear in through-hole applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 3-5 lead threads allows gradual thread engagement\u003c\/li\u003e\n\u003cli\u003eH2 thread limit ensures accurate 3B class of fit tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, non-coolant-through design compatible with standard tapping fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 8-32 UNC through holes in hardened steel, stainless steel, high-nickel alloy, titanium, and alloy steel workpieces.

Always use an appropriate tapping fluid or cutting oil matched to the material being threaded. Secure the workpiece fully before operation and verify spindle alignment to avoid tap breakage. Do not reverse direction until the tap has completed its cut cycle in CNC applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.126 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.751 inches (3\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 312TI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1105610708\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739401060658,"sku":"1105610708","price":58.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_c582b161-8a60-4a70-9c72-5882b3bf1a74.jpg?v=1788814142","url":"https:\/\/voomisupply.com\/products\/osg-1105610708-spiral-point-tap-8-32-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
