It features a plug chamfer for use in through-hole applications, three flutes, and a TiCN coating over a powdered metal (PMT15 grade) substrate. With an overall length of 4.331 inches and a thread length of 1.09 inches, this tap delivers consistent 2B class-of-fit threads cut in the right-hand direction. The H5 thread limit ensures dimensional accuracy within tight tolerance ranges. It is installed by machinists, toolroom technicians, and production operators working with manual taps, CNC tapping heads, or rigid tapping setups.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole tapping operations in both manual and CNC machine applications. The spiral point geometry pushes chips forward ahead of the cutting zone, making it particularly effective in through-hole setups where chip evacuation must be controlled. Compatible material applications include alloy steel, aluminum, cast aluminum, cast iron, hardened steel, high-carbon steel, low-carbon steel, medium-carbon steel, stainless steel, and die steel. It is part of OSG Series 16515 and carries the high-performance spiral point style designation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-11 UNC thread form with right-hand cutting direction and 2B class of fit\u003c\/li\u003e\n\u003cli\u003ePlug chamfer geometry for through-hole tapping applications\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves wear resistance and tool life across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003ePowdered metal PMT15 substrate provides enhanced toughness compared to standard HSS\u003c\/li\u003e\n\u003cli\u003eH5 thread limit for controlled dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral point design promotes forward chip ejection in through-hole cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole tapping in alloy steel, aluminum, cast aluminum, cast iron, hardened steel, high-carbon steel, low-carbon steel, medium-carbon steel, stainless steel, and die steel workpieces requiring a 5\/8-11 UNC thread to a 2B class of fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall in a machine spindle or hand-tapping setup configured for right-hand thread cutting. Power down or de-energize the machine before changing tooling and confirm the tap holder provides adequate axial float for rigid or semi-rigid tapping. Use an appropriate cutting fluid or tapping compound matched to the workpiece material to maximize tool life and thread quality. Inspect the tap for chipping or wear before each use, particularly when working with hardened or stainless steel materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\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: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.331 inches (110 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.091 inches (27.7 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal (PMT15)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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: 16515\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.238 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1651504008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742231429426,"sku":"1651504008","price":136.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a9ba9f9c2c944679aa461959aa68139.jpg?v=1788836057","url":"https:\/\/voomisupply.com\/products\/osg-1651504008-spiral-point-tap-5-8-11-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
