Built from micrograin carbide and coated with zirconium nitride (ZrN), this end mill handles tough ferrous and non-ferrous materials while maintaining edge integrity across extended runs. It features a 5\/8 inch mill diameter, a 3-flute right-hand cutting geometry, a 37-degree helix angle, and a chipbreaker profile that breaks chips to reduce heat buildup and recutting. Centercutting capability allows plunge entry without a pilot hole. Machinists and tool and die professionals use this type of end mill in CNC milling centers and manual knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing passes that require high metal removal rates, as well as finishing passes where surface quality is a priority. The chipbreaker geometry makes it particularly effective in deep-pocket milling where chip evacuation is critical. The 2 inch length of cut provides adequate reach for most standard cavity and profile work. The straight shank with a 5\/8 inch diameter fits standard ER and side-lock toolholders common in production and job shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eZrN coating improves wear resistance and reduces heat transfer at the cutting edge\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and resists deflection under load\u003c\/li\u003e\n\u003cli\u003eChipbreaker flute geometry reduces chip packing in deep-pocket and slotting operations\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eSingle-end construction with a straight 5\/8 inch shank fits standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use roughing finishing end mill for CNC and manual milling applications requiring a 5\/8 inch straight-shank toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the spindle and toolholder are clean and free of chips before seating the shank. Verify runout with a dial indicator before initiating a cut, as excessive runout accelerates edge wear on carbide tooling. Always bring the spindle to a full stop before changing or inspecting the end mill.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\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 (OAL)\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 95171867\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730089935154,"sku":"95171867","price":543.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab9b757c496d3b86e9d920972ad5a6f9.jpg?v=1788711614","url":"https:\/\/voomisupply.com\/products\/accupro-95171867-5-8-in-3-flute-roughing-end-mill-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
