It features a 0.5 inch diameter with a 0.03 inch corner radius, a 1.625 inch length of cut, and a 4 inch overall length. The chipbreaker geometry on all four flutes breaks chips into smaller segments, reducing cutting forces and heat buildup during heavy material removal. The variable pitch flute spacing minimizes harmonic chatter, making it well suited for high-feed roughing passes on CNC machining centers. The APLUS PVD coating improves wear resistance and tool life in ferrous materials. This tool is intended for installation and use by skilled machinists and CNC operators working with precision toolholders.\u003c\/p\u003e\u003cp\u003eThe 33542 is designed for roughing operations in low-alloy steel, medium alloy steel, tool steel, and cast iron. It performs in both mold and die work and general production machining where rapid stock removal is required before a finishing pass. The straight cylindrical shank with an h6 tolerance fits standard 0.5 inch precision toolholders and collet chucks. Centercutting capability allows plunge entry where needed. This tool is recommended for use with high precision toolholders to maintain runout within the 0.0005 inch maximum TIR specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eChipbreaker geometry on all four flutes reduces cutting forces and chip recutting during roughing\u003c\/li\u003e\n\u003cli\u003eVariable pitch flute spacing suppresses harmonic vibration and chatter\u003c\/li\u003e\n\u003cli\u003eAPLUS PVD coating provides enhanced wear resistance in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.03 inches reduces stress concentration at the cutting edge and extends tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits plunge milling entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral with standard length configuration for broad machine compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high precision toolholders. Primary workpiece materials are low-alloy steel, medium alloy steel, tool steel, and cast iron (Material Application Codes P and K).

Ensure the machine spindle is fully stopped and locked out before loading or removing the tool from the holder. Use a high precision toolholder to stay within the 0.0005 inch maximum TIR specification and prevent premature edge wear. Confirm tool projection and stick-out against the programmed depth of cut before running the first part.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: APLUS (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Low-Alloy Steel, Medium Alloy Steel, Tool Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.002 to 0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.002 to 0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HSVR-C-4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.326 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: HELICAL SOLUTIONS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 33542\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51751033012530,"sku":"33542","price":214.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c177c198f98f88cb58c443732cc4a023_c9e1194b-29ac-4e49-a147-aaf26fbb6aad.jpg?v=1788921290","url":"https:\/\/voomisupply.com\/products\/helical-solutions-33542-corner-radius-end-mill-1-2-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
