Built from powdered metal and finished with a TiCN coating, it is engineered for threading hardened steel, stainless steel, high-nickel alloys, titanium, alloy steel, and die steel. The tap features a 3-flute, right-hand spiral point design in an 8-32 UNC thread form with an H3 thread limit and a 2B class of fit. Overall length is 2.126 inches with a thread length of 0.381 inches. This tool is suited for machine tapping operations where chip-pushing performance and coating durability are required.\u003c\/p\u003e\u003cp\u003eThis tap is applied in precision threading of through-hole applications across ferrous and exotic alloy workpieces. Its plug chamfer makes it well-suited for starting in a hole and progressing through the full thread depth. Common installation environments include aerospace, tool-and-die, and precision machining shops where hard and abrasion-resistant materials are routinely threaded at 8-32 UNC. The TiCN coating extends tool life in high-wear conditions compared to uncoated tooling. Series 312 designation identifies this tap within the OSG product line for replacement and reorder purposes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePowdered metal construction provides high wear resistance for hard material threading\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in hardened steel and exotic alloys\u003c\/li\u003e\n\u003cli\u003eSpiral point design pushes chips forward, ideal for through-hole tapping\u003c\/li\u003e\n\u003cli\u003e3-flute configuration balances strength and chip clearance at 8-32 UNC\u003c\/li\u003e\n\u003cli\u003eH3 thread limit with 2B class of fit for standard tolerance internal threads\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in hardened steel, stainless steel, high-nickel alloy, titanium, alloy steel, and die steel.

Ensure the workpiece is securely fixtured and the spindle is properly aligned before engaging the tap. Use appropriate cutting fluid or tapping compound for the workpiece material to reduce heat buildup and extend tool life. Inspect the tap for wear or chipping before each use, particularly when working with hardened or exotic alloy materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 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: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\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: 0.381 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\u003eSeries\u003c\/strong\u003e: 312\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: 1757308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744535544114,"sku":"1757308","price":49.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d307e809d8e7daf9023768c61974e5da.jpg?v=1788857702","url":"https:\/\/voomisupply.com\/products\/osg-1757308-spiral-point-tap-8-32-unc-3-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
