Built from cobalt high-speed steel and finished with a multi-layer TiCN\/TiN coating, it delivers extended tool life in abrasive and work-hardening materials. The 45-degree helix angle promotes aggressive chip evacuation up and out of the hole, reducing the risk of chip packing in blind-hole applications. With a modified bottoming chamfer, it threads closer to the bottom of a blind hole than a plug tap. Overall length is 4.25 inches with a thread length of 1.22 inches and a maximum tapping depth of 2.08 inches. Installed by machinists and tool-room professionals on CNC machining centers and manual drill presses.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for right-hand threading in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The modified bottoming chamfer makes it particularly suited to blind-hole work where thread engagement close to the bottom of the bore is required. The H3 thread limit provides a tolerance class appropriate for standard-fit threaded fastener applications across general industrial and structural fabrication work. Coolant-through capability is not included on this tap, so conventional flood or mist coolant delivery applies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-10 UNC right-hand thread form with H3 thread limit for consistent tolerance control\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eMulti-layer TiCN\/TiN coating extends tool life in steel and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003e45-degree right-hand spiral flute promotes upward chip evacuation in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading near the base of blind-hole bores\u003c\/li\u003e\n  \u003cli\u003eFour flutes provide stable cutting geometry and consistent thread quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, stainless steel, cast iron, aluminum, and non-ferrous materials as noted in manufacturer specifications.

Ensure the workpiece is securely fixtured and the spindle is fully stopped before changing or inspecting tooling. Apply appropriate cutting fluid or flood coolant for the workpiece material to minimize heat buildup and extend tool life. Inspect the tap for chipping or wear before each use; a damaged tap run under power can seize in the bore and damage the workpiece.\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 UNC\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: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multi-layer TiCN\/TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches (108 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.22 inches (31 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 2.08 inches (53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.59 inches (14.99 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.17 inches (55 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.86 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.439 inches (11.15 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.69 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 6140719\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730424725810,"sku":"6140719","price":387.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af8afa12b525c43aa626a5abd1d36c59.jpg?v=1788717205","url":"https:\/\/voomisupply.com\/products\/kennametal-6140719-spiral-flute-tap-3-4-10-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
