It features a plug chamfer for through-hole threading applications and is manufactured from high speed steel with a TiN (titanium nitride) coating to extend tool life and reduce friction during the cutting cycle. The tap has 2 flutes, a D2 thread limit for controlled tolerance fits, and a thread length of 0.875 inches. Shank diameter is 0.194 inches. Thread direction is right hand. This tool is sized for M4.5 x 0.75 metric coarse thread form and is suited to production and maintenance machining environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is appropriate for threading through-holes in light manufacturing, maintenance and repair operations, and general machining applications where M4.5 x 0.75 metric coarse threads are specified. The plug chamfer makes it well suited for through-hole work where the tap can pass fully through the material. It is used by machinists, tool and die makers, and maintenance technicians working on metric-threaded assemblies in industrial and commercial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM4.5 x 0.75 metric coarse thread form for standard metric fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and increases cutting edge wear resistance\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) optimized for through-hole threading\u003c\/li\u003e\n  \u003cli\u003eD2 thread limit provides controlled tolerance for standard fit applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction suitable for steel, cast iron, and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; coolant-through feature not included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use spiral point tap for through-hole applications requiring M4.5 x 0.75 metric coarse internal threads.

Ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill diameter for M4.5 x 0.75 before tapping. Use an appropriate cutting fluid for the workpiece material. Never force the tap if resistance is encountered; back off to clear chips before continuing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4.5 x 0.75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eThread Limit\u003c\/strong\u003e: D2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 inches\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 (Titanium Nitride)\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: 0.2 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K020139AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51750508069170,"sku":"K020139AS25","price":69.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00d72ea4c9c41c6a061bbc9682c2e7cb.jpg?v=1788915985","url":"https:\/\/voomisupply.com\/products\/hertel-k020139as25-spiral-point-tap-m4-5x0-75-metric-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
