With a 0.75-inch cutting diameter, a 1.5-inch length of cut, and four spiral flutes ground to a 40-degree helix angle, it delivers aggressive chip evacuation and clean sidewall finishes. The micrograin carbide substrate provides the hardness and edge retention needed for high-speed machining on CNC mills and machining centers. This is a single-end, centercutting tool, meaning it can plunge directly into workpiece material without a pre-drilled pilot hole. Machinists and tool and die tradespeople working in job shops or production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill suits general-purpose slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The 0.75-inch shank diameter matches ER collet chucks, side-lock holders, and hydraulic chucks in that size range. With a 4.0-inch overall length and no extended reach design, it offers solid rigidity for standard-depth operations. The right-hand cut and right-hand flute configuration is the most common orientation for conventional CNC spindle rotation. The uncoated finish makes it straightforward to resharpen when edge wear occurs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eUncoated finish supports easy resharpening and use across a broad material range\u003c\/li\u003e\n\u003cli\u003eTight mill diameter tolerance of +0.001 \/ -0.000 inches for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank solid carbide square end mill for use in 0.75-inch ER collet, side-lock, or hydraulic toolholding systems on CNC vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer torque specifications for the toolholder in use. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Confirm shank seating depth meets the toolholder minimum engagement requirement to avoid pullout under cutting loads. Inspect the collet or chuck bore for runout before tightening to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eCentercutting\u003c\/strong\u003e: Yes\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: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.001 \/ -0.000 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\u003eWeight\u003c\/strong\u003e: 0.835 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: 12177094\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740634972466,"sku":"12177094","price":264.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74e7a220eebf46d0ed41020bcd236430.jpg?v=1788826362","url":"https:\/\/voomisupply.com\/products\/accupro-12177094-square-end-mill-0-75in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
