It produces a 1\/4-20 UNC thread to a Class 2B fit with an H5 thread limit, making it suitable for general-purpose fastener clearance work. The tap is manufactured from powdered metal and coated with titanium carbonitride (TiCN), which improves surface hardness and wear resistance compared to standard high-speed steel. Three flutes and a plug chamfer allow the tap to push chips forward ahead of the cutting zone, a geometry well suited to through-hole tapping in steel, stainless, and similar materials. Machinists and tool-and-die professionals are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole tapping operations on CNC machining centers, turret lathes, or manual drill presses equipped with a tapping attachment. The plug chamfer requires adequate thread engagement depth and is not appropriate for blind holes where chip evacuation is restricted. The 1\/4-20 UNC thread form is one of the most common inch-series fastener threads in North American manufacturing and maintenance applications, appearing in structural assemblies, machine components, and equipment frames across light industrial and commercial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread form, Class 2B fit with H5 thread limit for standard tolerance threading\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and extends tool life versus uncoated taps\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction provides uniform grain structure for consistent cutting performance\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral point geometry pushes chips forward, keeping the cutting zone clear in through-hole work\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with right-hand thread direction for standard through-hole tapping setups\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup on standard machine tool spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC spiral point plug tap suitable for use in through-hole tapping applications on compatible CNC and manual machine tool setups accepting standard tap shank dimensions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be installed by a qualified machinist following standard tapping procedures for the workpiece material and machine type in use. Ensure the spindle is at a full stop and all motion has ceased before changing or inspecting the tap. Use appropriate tapping fluid or cutting oil for the workpiece material to reduce friction and extend tap life. Do not force a tap that has stalled or reversed unexpectedly, as this can cause breakage and workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\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: H5\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: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 30085-00C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734938845490,"sku":"30085-00C","price":49.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4af86002b72ecc6110faf36c954d3c93.jpg?v=1788768348","url":"https:\/\/voomisupply.com\/products\/accupro-30085-00c-spiral-point-tap-1-4-20-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
