With a 0.9843-inch mill diameter and a 1.4961-inch length of cut, this single-end tool delivers consistent material removal in both roughing and finishing passes. The micrograin carbide substrate provides hardness and wear resistance at the cutting edge. A TiCN (Titanium Carbonitride) coating reduces friction and extends tool life in harder workpiece materials. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Licensed machinists and CNC programmers specify this geometry for applications where surface finish and dimensional accuracy are critical.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for vertical and horizontal milling centers, CNC machining centers, and manual knee mills running at appropriate surface footage for carbide tooling. The right-hand cut and right-hand spiral flute configuration is the standard setup for conventional and climb milling on most production equipment. The centercutting design allows plunge entry, making it viable for slot milling, pocket milling, and contour operations without a pre-drilled pilot hole. Regular length classification fits the majority of general-purpose fixturing setups without excessive overhang.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.9843-inch (25.00 mm) mill diameter with a tolerance of +0.000 \/ -0.002 inches for consistent fit\u003c\/li\u003e\n  \u003cli\u003e1.4961-inch (38.00 mm) length of cut supports full-depth slot and pocket work\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for hardness and extended tool life\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and improves performance in harder materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute  -  standard orientation for most CNC and manual mills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill for standard ER or side-lock toolholders accepting a 25.00 mm (0.9843-inch) shank diameter. Shank diameter tolerance is -0.0001 \/ -0.0004 inches for a secure, low-runout fit in precision collet systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician following the machine tool manufacturer guidelines for toolholder torque and runout verification. Ensure the spindle and toolholder are clean and free of chips or debris before seating the shank. Overall length is 92.00 mm, so verify clearance with the workpiece, fixture, and machine travel limits before running a program. Follow your shop safety procedures for RPM limits, cutting fluid application, and secure workholding before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.9843 inches (25.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.4961 inches (38.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 92.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 25.00 mm\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, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eLength Type\u003c\/strong\u003e: Regular\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\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12182689\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739817771314,"sku":"12182689","price":525.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0a64d54ddfeec7bc6f0cb2d325ee2f1.jpg?v=1788819205","url":"https:\/\/voomisupply.com\/products\/accupro-12182689-square-end-mill-0-9843-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
