It features a 1-inch mill diameter with a 2-inch length of cut, a 1-inch shank diameter, and a 5-inch overall length. The three-flute, right-hand spiral geometry runs at a 37-degree helix angle, promoting efficient chip evacuation and smooth surface finishes. A ZrN (zirconium nitride) coating adds hardness and heat resistance, extending tool life in demanding cutting applications. The micrograin carbide substrate supports higher cutting speeds than standard carbide grades. This tool is installed and operated by machinists and CNC programmers in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for peripheral and slot milling in ferrous and non-ferrous materials where a regular-length, single-end tool is appropriate. The center-cutting geometry allows plunge entry, giving operators flexibility in pocket milling and profiling operations. With no chipbreaker and a fixed helix design, it is best applied where consistent, predictable chip loads are required. It is a single-end tool, meaning once the cutting end is worn it is not reversible.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch mill diameter with plus 0.000 \/ minus 0.002 inch diameter tolerance\u003c\/li\u003e\n\u003cli\u003e2-inch length of cut suitable for moderate-depth slotting and profiling\u003c\/li\u003e\n\u003cli\u003e37-degree right-hand helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eZrN coating for increased surface hardness and thermal resistance\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for standard 1-inch straight-shank tool holders used in CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a compatible 1-inch straight shank tool holder or collet system; verify runout and holder condition before clamping. Machinists should follow shop-specific speeds and feeds for the workpiece material and machine spindle. Ensure the spindle is fully stopped and the machine is in a safe state before changing or inspecting the end mill. Discard or regrind when cutting edges show visible wear to avoid workpiece damage or tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.000 \/ minus 0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 \/ minus 0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 315205\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731056329010,"sku":"315205","price":642.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99884a2e257d3855b06424517dc1db71.jpg?v=1788726341","url":"https:\/\/voomisupply.com\/products\/accupro-315205-square-end-mill-1-in-3-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
