Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced galling in difficult materials. The plug chamfer configuration distributes cutting forces over multiple leading threads, making it suitable for through-hole tapping operations. With a 2-flute spiral point geometry, chips are pushed ahead of the tap rather than packed into the flute, helping maintain clean threads and reducing the risk of tap breakage in production environments. Licensed tradespeople and machinists use this tap in manual and CNC tapping applications across fabrication, maintenance, and repair work.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole tapping in cast iron, stainless steel, and steel. The 6H thread class of fit meets standard metric tolerance requirements for general mechanical assemblies. The D4 thread limit designation indicates oversize compensation to account for TiN coating buildup and material springback, maintaining dimensional accuracy in the finished thread. It is commonly used in job shops, maintenance facilities, and production environments where consistent metric thread quality is required across a range of ferrous workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM4 x 0.7 metric coarse thread form with 6H class of fit\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with TiN coating for improved wear resistance\u003c\/li\u003e\n\u003cli\u003e2-flute spiral point geometry pushes chips forward through the hole\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for through-hole tapping applications\u003c\/li\u003e\n\u003cli\u003eD4 thread limit for dimensional accuracy with coated taps\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping M4 x 0.7 metric coarse through-holes in cast iron, stainless steel, and steel workpieces.

Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the workpiece surface before engagement. Apply appropriate cutting fluid for the workpiece material  -  sulfurized oil for steel, water-soluble coolant for stainless  -  to extend tap life and improve thread finish. Inspect the tap for wear or chipping before each use; a damaged tap should not be reused.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4 x 0.7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 6H\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: 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\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2351T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0167 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1545213\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744375734578,"sku":"1545213","price":48.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3a1ba6b6915344fcdecd138edadc643.jpg?v=1788855997","url":"https:\/\/voomisupply.com\/products\/kennametal-1545213-spiral-point-tap-m4x0-7-metric-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
