It carries a 1\/4 inch cutting diameter, a 1\/2 inch length of cut, and a 2-1\/2 inch overall length. The tool features a variable index geometry that reduces harmonic vibration during aggressive cuts, and an APLUS PVD coating that extends tool life in ferrous materials. The 0.1250 inch nose radius produces a true ball-end profile suited to contouring, profiling, and finishing operations. Single-end construction with a straight cylindrical shank makes it straightforward to chuck in standard toolholders.\u003c\/p\u003e\n\u003cp\u003eThis end mill targets CNC machining centers and manual mills running steel, tool steel, and cast iron workpieces in job shop and production environments. It is rated for both roughing and finishing passes, making it a practical choice when a single tool must handle material removal and surface finish in the same setup. The right-hand cut and right-hand spiral flute direction are standard for conventional CNC spindle rotation. No coolant-through capability is present, so flood or mist coolant at the tool periphery is the appropriate delivery method for heat management in ferrous stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-flute solid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eAPLUS PVD coating improves hardness and lubricity for extended tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eBall end profile with 0.1250 inch nose radius suited to 3D contouring and profiling\u003c\/li\u003e\n  \u003cli\u003eRated for both roughing and finishing material removal in a single tool\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight cylindrical 1\/4 inch shank fits standard ER and set-screw toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for milling steel, stainless steel, and cast iron workpieces.

Confirm runout does not exceed the 0.0005 inch TIR maximum before cutting. Power down and lock out the spindle before changing or setting tool length offsets manually. Do not exceed the 1\/2 inch reach length when engaging the full depth of cut, as extending beyond the rated length of cut significantly reduces tool rigidity and can cause premature failure.\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\u003eReach Length\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\u003eNose Radius\u003c\/strong\u003e: 0.1250 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\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 End\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0620 \/ -0.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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: 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: 56142\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51728148103474,"sku":"56142","price":75.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9c8bc55c4f31badf2181f4032989dca.jpg?v=1788688793","url":"https:\/\/voomisupply.com\/products\/helical-solutions-56142-ball-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
