Part of the HSVR-C-4 series, it features a chipbreaker geometry and variable pitch design that reduces harmonics and chatter during heavy material removal. The 0.03-inch corner radius protects the cutting edge and improves tool life in high-load applications. At 0.75 inches in diameter with a 3.25-inch length of cut and 6-inch overall length, this is a long-reach tool suited for deep-pocket and slotting work. The Aplus PVD coating provides thermal resistance and lubricity for extended performance in ferrous materials. Installed by machinists and CNC tooling professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for roughing passes in low-alloy steel, medium alloy steel, tool steel, and cast iron. The long length of cut makes it well suited for deep cavities, tall workpiece features, and mold or die work where reach is a requirement. The variable pitch flute spacing reduces resonance at higher feed rates, making it a practical choice for high-efficiency milling strategies. It requires high-precision toolholders to maintain runout within the 0.0005-inch maximum TIR specification. Single-end, right-hand cutting, with a straight cylindrical shank for standard collet or end mill holder mounting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eChipbreaker geometry reduces cutting forces and improves chip evacuation during roughing\u003c\/li\u003e\n  \u003cli\u003eVariable pitch flutes minimize chatter and harmonic vibration\u003c\/li\u003e\n  \u003cli\u003e0.03-inch corner radius extends edge life and reduces stress concentration at the tool corner\u003c\/li\u003e\n  \u003cli\u003eAplus PVD coating provides heat resistance and surface lubricity for ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eLong 3.25-inch length of cut supports deep-pocket and extended-reach applications\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry where required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eIntended for use with high-precision toolholders.

Ensure the machine spindle is fully stopped and the control is in an appropriate safe state before changing tooling. Use a high-precision collet or end mill holder to maintain runout at or below the 0.0005-inch TIR maximum. Verify tool projection and stick-out are appropriate for the depth of cut to avoid deflection on this long-reach tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 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\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 \/ 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\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.062 \/ 0.062 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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\u003ePitch\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Low-Alloy Steel, Medium Alloy Steel, Tool Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HSVR-C-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.071 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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 33692\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51739576303922,"sku":"33692","price":542.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c177c198f98f88cb58c443732cc4a023_97f5f965-de34-4afe-9e9d-03cd79a3d8c1.jpg?v=1788816510","url":"https:\/\/voomisupply.com\/products\/helical-solutions-33692-corner-radius-end-mill-3-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
