Built from high speed steel with a titanium nitride (TiN) coating, it provides extended tool life and reduced friction during cutting. The plug chamfer style makes it well suited for starting threads in through holes where the tap can advance freely. With 2 flutes and a right-hand thread direction, it cuts 5\/16-18 UNC threads to a Class 2B fit and H2 thread limit. This tap is used by machinists, maintenance technicians, and fabricators working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading operations in cast iron and steel workpieces. The spiral point geometry pushes chips forward ahead of the tap rather than packing them into the flutes, making it effective in continuous through-hole applications. At 2.72 inches overall length with an 11\/16-inch thread length, it fits standard tap holders and CNC tapping heads. It is not designed for blind-hole applications where chip evacuation forward is not possible.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form, Class 2B fit, H2 thread limit for standard tolerance threading\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends cutting life compared to uncoated HSS\u003c\/li\u003e\n  \u003cli\u003eSpiral point (gun tap) geometry pushes chips forward, ideal for through-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for easy thread starting in through holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in cast iron and steel.

Secure the workpiece before operation and ensure the spindle is aligned axially with the hole to prevent tap breakage. Use a cutting fluid or tapping compound appropriate for the workpiece material. Inspect the tap for wear or chipping before each use and replace if cutting edges show damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\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: H2\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\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.72 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.69 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.45 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\u003eThreads per Inch\u003c\/strong\u003e: 18\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: 1011TN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C55319\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51715856859442,"sku":"C55319","price":47.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2c7f73657f8b50caf97ff64334b5436_657bb7d2-ac5f-433a-a318-6a9268bdbc19.jpg?v=1788519093","url":"https:\/\/voomisupply.com\/products\/cleveland-c55319-spiral-point-tap-5-16-18-unc-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
