It features a plug chamfer for gradual thread engagement and three flutes that push chips forward ahead of the cutting zone, keeping the hole clear during operation. Manufactured from high-speed steel (HSS) and coated with titanium nitride (TiN), this tap delivers improved wear resistance and lubricity compared to uncoated HSS tooling. With an overall length of 2.938 inches and a thread length of 0.776 inches, the 2886105 fits standard tap holders and is sized for use in manual and machine tapping setups. Installation and use are appropriate for machinist and tooling professionals working in production or maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading aluminum, cast aluminum, low-carbon steel, and medium-carbon steel workpieces in through-hole configurations. The spiral point design makes it well-suited for machine tapping where chip evacuation is a priority. A 2B class of fit produces standard commercial internal thread tolerance, appropriate for general fastener and assembly applications in both light manufacturing and maintenance\/repair operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF thread form with right-hand direction and 2B class of fit\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, reducing chip packing in through holes\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides gradual entry and suits both hand and machine tapping\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with TiN coating for extended tool life and reduced galling\u003c\/li\u003e\n  \u003cli\u003eThree flutes provide good chip clearance in softer ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup in standard tapping applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel.

Secure the workpiece firmly before tapping to prevent movement and thread distortion. Apply appropriate cutting fluid for the workpiece material before and during the tapping operation. Inspect the tap for wear or chipping before each use and replace any tap showing visible damage to the cutting edges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.776 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 287\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: 2886105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734705832242,"sku":"2886105","price":32.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6772299b19206dc6822b428975542c92.jpg?v=1788765434","url":"https:\/\/voomisupply.com\/products\/osg-2886105-spiral-point-tap-3-8-24-unf-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
