Built from powdered metal with a TiN (titanium nitride) coating, it delivers extended wear resistance in hard and high-tensile materials. The tap is configured with a modified bottoming chamfer, allowing threading close to the bottom of blind holes. Available with 3 or 5 flutes in a fast flute style with a 40-degree helix angle, it efficiently evacuates chips upward during the cut. The 2B class of fit meets standard unified thread tolerances, and the H3\/H4 thread limit provides consistent sizing across production runs. Overall length is 3.543 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for threading blind holes in heat treatable hardened steel, high tensile steel, and tool steel. The high helix angle and spiral flute geometry make it well suited for through-spindle coolant setups, though coolant-through is not built into this model. It is commonly used in precision machining, toolroom, and production environments where tight thread tolerances and difficult materials are the norm. Licensed machinists and tooling specialists are the primary installers and operators of this product.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eModified bottoming chamfer for threading close to the base of blind holes\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends tool life in hardened and high-tensile steels\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation in blind hole applications\u003c\/li\u003e\n  \u003cli\u003eH3\/H4 thread limit supports consistent 2B class of fit tolerances\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction provides high hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eFast flute style reduces cutting torque in difficult materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading in heat treatable hardened steel, high tensile steel, and tool steel.

Ensure the workpiece is securely fixtured and the spindle is aligned to the hole axis before engaging the tap. Follow machine-specific speed and feed recommendations for the work material and tap size. Inspect the tap for wear or chipping before each use and replace at first sign of deterioration to avoid thread damage or breakage 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: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\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\/H4\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\u003eNumber of Flutes\u003c\/strong\u003e: 3 or 5\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Heat Treatable Hardened Steel, High Tensile Steel, Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.543 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.377 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.238 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\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: 3995\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 9039950079380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730520768818,"sku":"9039950079380","price":56.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28d8e72e5ad52e626000f9075b372b4d.jpg?v=1788718908","url":"https:\/\/voomisupply.com\/products\/guhring-9039950079380-spiral-flute-tap-5-16-24-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
