Built from cobalt high-speed steel and finished with GUHRING's Ignator coating, this tap delivers the wear resistance and cutting performance required in demanding production and maintenance environments. It is configured for UNC threading at 40 threads per inch, sized at 5-40, with a modified bottoming chamfer for threading close to the bottom of blind holes. The 3-flute spiral design evacuates chips upward out of the hole, reducing the risk of chip packing. With an overall length of 1.941 inches and a shank diameter of 0.141 inches, this tap fits standard tap holders and chucks used in CNC and manual machine setups.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for production threading operations in machine shops, maintenance and repair facilities, and toolroom environments. The modified bottoming chamfer makes it the correct choice where thread engagement close to the blind hole floor is required. The H2 thread limit and 2B\/3B class of fit cover the most common tolerance requirements for standard UNC fastener applications. Compatible material applications include alloy steel, alloy tool steel, aluminum alloy, case-hardened steel, cast iron, ductile iron, free-cutting steel, heat-treated steel, malleable cast iron, stainless steel, structural steel, and tool steel. Machinists, tool and die makers, and CNC operators are the primary users of this tap.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for superior heat and wear resistance in tough materials\u003c\/li\u003e\n  \u003cli\u003eIgnator finish reduces friction and extends tool life across a broad material range\u003c\/li\u003e\n  \u003cli\u003e3-flute right-hand spiral design promotes upward chip evacuation in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading closer to the bottom of blind holes than a standard plug tap\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit with 2B\/3B class of fit covers standard UNC tolerance requirements\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle supports fast, efficient cutting in ductile and harder materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style spiral flute tap for use in standard tap holders and machine spindles accepting a 0.141-inch shank diameter.

Secure the tap in a properly sized tap holder or collet before use, and ensure the machine spindle is at a complete stop before loading or removing the tool. Apply appropriate cutting fluid or tapping compound for the workpiece material to maximize tool life and thread quality. Follow shop safety protocols and applicable OSHA machine guarding requirements when operating drilling and tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\/3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.941 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.709 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.434 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches\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\/Finish\u003c\/strong\u003e: Ignator\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: 4881\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9048812031750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730587975986,"sku":"9048812031750","price":37.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed18124a2fea51be3bbdf374250e0745_b36f0e79-6b40-4a6d-bde3-7c0180f73915.jpg?v=1788720009","url":"https:\/\/voomisupply.com\/products\/guhring-9048812031750-spiral-flute-tap-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
