With a 7\/8-inch diameter and three spiral flutes at a 40-degree helix angle, it delivers efficient chip evacuation and stable cutting performance. The bright uncoated finish suits applications where coating is not required or where regrinding is anticipated. Micrograin carbide construction provides hardness and edge retention well above high-speed steel alternatives. This tool is installed and operated by machinists and CNC operators in job shops, tool rooms, and production facilities.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for peripheral and slot milling in ferrous and non-ferrous materials where a 7\/8-inch diameter tool path is required. The 1-3\/4-inch length of cut accommodates moderate-depth passes, while the 4-inch overall length fits standard toolholders for vertical and horizontal milling machines and CNC machining centers. The right-hand cut and right-hand flute configuration matches the most common spindle and fixturing setups. Center-cutting capability allows plunge entry without pre-drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior edge retention and wear resistance\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eThree spiral flutes balance chip clearance with radial rigidity\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design enables direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for regrinding or use in applications incompatible with coatings\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard square end mill replacement for 7\/8-inch diameter toolholder setups on vertical mills, horizontal mills, and CNC machining centers requiring a regular-length, three-flute solid carbide tool.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify toolholder bore size and runout tolerance before seating the shank, noting the shank diameter tolerance of -0.0001 to -0.0004 inches. Confirm feed rate, spindle speed, and depth of cut are set per the material being machined before initiating a cut cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/4 inches (1.75 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/8 inch (0.875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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 (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 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: 12182148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730451104050,"sku":"12182148","price":258.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3e63044e8b1c840f3bb28720fffe2ec.jpg?v=1788717681","url":"https:\/\/voomisupply.com\/products\/accupro-12182148-square-end-mill-7-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
