It features a plug chamfer, three flutes, and a titanium carbonitride (TiCN) coating over a high-speed steel-E (HSS-E) substrate. The TiCN coating increases surface hardness and reduces friction, extending tool life in demanding threading applications. With a D4 thread limit and right-hand thread direction, this tap is suited for through-hole tapping where the spiral point action pushes chips forward ahead of the cutting zone. Overall length is approximately 2.126 inches with a thread length of approximately 0.327 inches and a shank diameter of approximately 0.168 inches. Machinists and tool-and-die technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis tap is rated for use in aluminum, hardened steel, stainless steel, high-carbon steel, low-carbon steel, medium-carbon steel, alloy steel, die steel, and cast iron. It is well suited for production threading in machine shop environments where a variety of workpiece materials are encountered on the same tooling setup. The plug chamfer provides a gradual lead-in that distributes cutting forces across several threads, making it appropriate for both CNC tapping centers and manual machines with a tapping head. It is not designed for blind-hole applications where chip evacuation forward is not possible.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating increases surface hardness and lubricity for extended tool life\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel-E (HSS-E) substrate provides toughness across a broad material range\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 3 flutes pushes chips forward, ideal for through-hole tapping\u003c\/li\u003e\n\u003cli\u003eD4 thread limit suits standard tolerance threading requirements\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for conventional tapping operations\u003c\/li\u003e\n\u003cli\u003eCompatible with aluminum, stainless steel, alloy steel, die steel, and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole tapping across a wide range of workpiece materials including aluminum, stainless steel, hardened steel, carbon steel variants, alloy steel, die steel, and cast iron.

Before use, verify that the spindle speed and feed rate are appropriate for the workpiece material and tap diameter. Apply cutting fluid or tapping compound suitable for the material being threaded to reduce heat buildup and extend tap life. Inspect the tap for chipping or wear before each use and replace if cutting edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel-E (HSS-E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\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: D4\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: 2.126 inches (54 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.327 inches (8.3 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches (4.2672 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 289\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.014 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 2890608\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744013648178,"sku":"2890608","price":50.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dcf014285ef51fd8266d01535cc6b1de.jpg?v=1788852926","url":"https:\/\/voomisupply.com\/products\/osg-2890608-spiral-point-tap-plug-ticn-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
