The spiral point geometry pushes chips ahead of the cutting action, keeping the flutes clear during machine tapping and reducing the risk of chip packing. Built from high speed steel with an oxide finish, this tap handles the mechanical demands of production and maintenance threading. It cuts a 1\/2-13 UNC thread to a 2B class of fit with an H3 thread limit, making it suitable for standard fastener-clearance applications. Three flutes provide a balance of chip clearance and cutting edge strength for this thread size.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole applications in cast iron and steel. The plug chamfer — typically 3 to 5 threads of lead — makes it the standard choice for machine tapping where the tool passes fully through the material. It is commonly used in CNC machining centers, manual knee mills, and production tapping operations. The right-hand cutting direction and 1\/2-13 UNC specification align with the most common inch-standard fastener thread used in general mechanical assemblies and structural connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point design pushes chips forward, suited for through-hole machine tapping\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eOxide finish improves lubrication retention during cutting\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for standard through-hole entry and lead-in\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit and 2B class of fit for general-purpose inch-standard fastener threads\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement; compatible with flood coolant or cutting oil applied externally\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.

Before starting, confirm the tap holder runout is within acceptable limits and that the workpiece is securely fixtured. Apply cutting oil or flood coolant appropriate for the workpiece material. Do not reverse the tap under power without confirming the machine is set for synchronized reversal, as unsupported reversal can fracture the tap in the hole.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 13\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\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\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: Oxide\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: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.656 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 6.99 mm\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: 1011BO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.7 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: C57636\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51711081087282,"sku":"C57636","price":43.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fec7ce4cef5e3cb6fa66833532e67304_fac2c6f4-2269-44a7-b48b-377ded632483.jpg?v=1788474207","url":"https:\/\/voomisupply.com\/products\/cleveland-c57636-spiral-point-tap-1-2-13-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
