This tool accommodates workpiece diameters from 1\/8 inch to 2-1\/2 inches and produces right hand cut patterns using two knurl wheels. The rectangular shank measures 4-1\/4 inches in length, 1 inch in width, and 3\/4 inch in height, making it compatible with standard lathe tool posts. Overall tool length is 6-1\/16 inches and overall width is 2-1\/2 inches. The SW4 series designation identifies the shank and frame size for correct holder selection. Machinists and toolroom technicians use this knurler for grip surfaces on shafts, handles, and precision components.\u003c\/p\u003e\n\u003cp\u003eThis knurler is suited for production and jobshop turning operations where a consistent diamond or diagonal knurl pattern is needed across a range of part diameters. The scissor-and-straddle design applies balanced radial pressure to both sides of the workpiece, reducing deflection on slender parts compared to single-wheel bump-style knurlers. Included knurl wheels cover left hand diagonal and right hand diagonal patterns, giving the operator flexibility for combined diamond patterns or single-direction knurling without changing tools. It is used in metalworking environments on steel, aluminum, and similar machinable materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCapacity range from 1\/8 inch to 2-1\/2 inch workpiece diameter\u003c\/li\u003e\n  \u003cli\u003eScissor and straddle design balances radial cutting forces to minimize part deflection\u003c\/li\u003e\n  \u003cli\u003eIncludes two knurl wheels: left hand diagonal and right hand diagonal patterns\u003c\/li\u003e\n  \u003cli\u003eRight hand cut orientation for standard lathe spindle rotation\u003c\/li\u003e\n  \u003cli\u003eRectangle shank: 4-1\/4 inches long x 1 inch wide x 3\/4 inch tall for secure tool post clamping\u003c\/li\u003e\n  \u003cli\u003eSW4 series frame for consistent sizing and replacement wheel compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit knurling tool for standard lathe tool posts accepting a 1 inch wide by 3\/4 inch tall rectangular shank in the SW4 series configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Power down and lock out the lathe spindle before mounting or adjusting the knurler in the tool post. Ensure the shank is fully seated and clamping screws are tightened to tool post manufacturer specifications before engaging the workpiece. Follow shop safety procedures when adjusting knurl wheel pressure and confirm correct wheel pattern selection before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e: 1\/8 to 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnurl Wheel Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 4-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Knurls Required\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnurl Patterns Included\u003c\/strong\u003e: Left Hand Diagonal, Right Hand Diagonal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SW4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5 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: DORIAN TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73310121485\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DORIAN TOOL","offers":[{"title":"Default Title","offer_id":67906918908210,"sku":"73310121485","price":905.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1487672a4cf7a74896e69755d760626c.jpg?v=1791172470","url":"https:\/\/voomisupply.com\/products\/dorian-tool-73310121485-scissor-straddle-knurler","provider":"Voomi Supply","version":"1.0","type":"link"}
