Built from high speed steel (HSS) with an oxide finish, it provides lubricity and basic corrosion resistance during cutting operations. The plug chamfer — typically 3 to 5 threads — makes it suited for through-hole threading applications where the tap can pass fully through the workpiece. With an overall length of 4.25 inches, a thread length of 2 inches, and a shank diameter of 0.59 inches, this tap fits standard 3\/4-inch tap holders and is sized for production and maintenance machining environments. The H3 thread limit specifies a ground oversize tolerance for consistent fit with standard UNC class fits.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for use in cast iron, ductile iron, stainless steel, and steel. The spiral point geometry pushes chips forward ahead of the tap, making it effective in through-hole applications where chip evacuation is critical. It is commonly used in job shops, production machining, and maintenance repair operations (MRO) where 3\/4-10 UNC threads are required in ferrous workpieces. Licensed machinists and tool-and-die professionals are the primary users. Coolant-through capability is not included on this tap, so conventional flood or cutting oil lubrication applies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-10 UNC spiral point design pushes chips ahead for clean through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction withstands heat and wear in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eOxide finish adds lubricity and basic surface protection during cutting\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) optimized for through-hole applications\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures consistent tolerance for standard UNC class fits\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry balances chip load and cutting efficiency in the rated material group\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for threading cast iron, ductile iron, stainless steel, and steel.

Power down and secure the workpiece before tool changes. Apply cutting oil or flood coolant appropriate for the workpiece material — stainless steel and cast iron each require compatible lubricants. Right-hand cutting direction only; confirm spindle rotation before engaging the tap to prevent breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Ductile Iron, Stainless Steel, Steel\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4131215\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732569784626,"sku":"4131215","price":139.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/916fa0ea059b2ba82a39e4087e7e75c0.jpg?v=1788744540","url":"https:\/\/voomisupply.com\/products\/kennametal-4131215-spiral-point-tap-3-4-10-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
