It is manufactured from vanadium high-speed steel and features a titanium carbonitride (TiCN) coating that improves wear resistance and reduces galling in demanding applications. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard taper or plug tap. With a 45-degree helix angle and three right-hand flutes, this tap efficiently evacuates chips upward out of the hole, making it well suited for short-chipping and interrupted-cut materials. It carries an H3 thread limit and a 3B class of fit for standard tolerance threading.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in stainless steel, high-carbon steel, low-carbon steel, and medium-carbon steel. It is a production-grade tool used by machinists and tool-and-die professionals in CNC tapping, manual tapping heads, and turret lathe applications. The modified bottoming geometry makes it a practical choice for blind-hole work where thread depth close to the bottom is required. The TiCN coating extends tool life in abrasive and work-hardening materials such as stainless steel. Coolant-through capability is not included in this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form with H3 thread limit and 3B class of fit for standard tolerance applications\u003c\/li\u003e\n  \u003cli\u003e45-degree right-hand spiral flutes evacuate chips upward, reducing re-cutting in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading nearer to hole bottom than plug or taper configurations\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves surface hardness and wear resistance in stainless and carbon steel\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel construction provides toughness for interrupted cuts and tough alloys\u003c\/li\u003e\n  \u003cli\u003ePart of the OSG EXOTAP VA3 series, engineered for high-performance tapping in ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading 1\/2-13 UNC holes in stainless steel, high-carbon steel, low-carbon steel, and medium-carbon steel.

Ensure the workpiece is securely fixtured and the spindle is aligned to the hole axis before engaging the tap to prevent breakage. Use a cutting fluid or tapping compound appropriate for the workpiece material, particularly when tapping stainless steel. Inspect the tap for wear or chipping before each use and replace at the first sign of degradation to avoid thread damage in 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: 1\/2-13 UNC\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: 13\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread 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\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel\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: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.614 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 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: Stainless Steel, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.101 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EXOTAP VA3\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1733408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728447504690,"sku":"1733408","price":89.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4680550ef89b181fc86b12c31342a84c.jpg?v=1788691335","url":"https:\/\/voomisupply.com\/products\/osg-1733408-spiral-flute-tap-1-2-13-unc-ticn-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
