It carries a 0.25-inch mill diameter, a 0.5-inch length of cut, and a 2.5-inch overall length on a straight-cylindrical 0.25-inch shank. The variable-index flute geometry reduces harmonic chatter during aggressive cuts, making this tool well suited for both roughing and finishing passes in difficult-to-machine materials. Licensed machinists and CNC operators working on production or job-shop floors are the primary users of this end mill.\u003c\/p\u003e\n\u003cp\u003eThe 83283 is engineered for primary use in stainless steels, superalloys, and titanium, with secondary capability in general steel and cast iron. Its standard-length profile and right-hand cut with right-hand spiral flutes make it a practical choice for vertical machining centers and CNC milling machines running stainless components, aerospace hardware, medical parts, and high-temperature alloy workpieces where surface finish and dimensional accuracy are both critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate provides rigidity and heat resistance at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eTplus PVD coating improves lubricity and extends tool life in stainless and superalloy cuts\u003c\/li\u003e\n  \u003cli\u003eVariable-index flute spacing reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration balances chip evacuation with finish quality for both roughing and finishing\u003c\/li\u003e\n  \u003cli\u003eBall nose profile with 0.125-inch nose radius enables contour milling and 3D surface work\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flutes compatible with standard CNC spindle direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC milling applications targeting stainless steel, superalloys, titanium, hard materials, steel, and cast iron, per the HELICAL SOLUTIONS Series 4 Flute - Ball - Variable Pitch (Tplus) End Mills for Stainless Steels and High Temp Alloys product family.

Ensure the machine spindle is fully stopped and the tool changer is in a safe state before inserting or removing the end mill. Seat the shank fully into a properly sized collet or hydraulic holder and torque the retention mechanism to the tool holder manufacturer specification. Verify runout against the stated TIR maximum of 0.0005 inches with a dial indicator before beginning production cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.5000 inches\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: Tplus (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel; Superalloys and Titanium; Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel; Stainless Steel; Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.057 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: 83283\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51743961383218,"sku":"83283","price":85.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e55b1e1cd101980ba6076c5607039ca5_12bb490b-b9c8-4196-91c7-f47282401b99.jpg?v=1788852005","url":"https:\/\/voomisupply.com\/products\/helical-solutions-83283-ball-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
