With a 29\/64 inch (0.4531 inch) cutting diameter and 4 spiral flutes ground to a 40-degree helix angle, this tool delivers efficient chip evacuation and a smooth cutting action in a wide range of ferrous and non-ferrous materials. The stub-length configuration keeps deflection low, making it well-suited for rigid setups and tighter tolerances. The bright, uncoated finish on micrograin carbide substrate provides a sharp, consistent edge right out of the packaging. This end mill is installed and used by machinists, toolroom operators, and CNC programmers in job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard milling machine spindles and CNC machining centers using a 1\/2 inch shank. The stub length overall measurement of 2-1\/2 inches and a 5\/8 inch length of cut make it appropriate for shallow-to-moderate pocket milling, slotting, profiling, and contouring operations. The centercutting design allows direct plunge entry into the workpiece. Right-hand cut and right-hand flute geometry follow the most common spindle rotation standard, making this a straightforward drop-in for most setups without special toolholder adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eStub-length design minimizes tool deflection for tighter tolerances\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suited for aluminum, brass, and general-purpose steel applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — compatible with standard CNC and manual mill spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/2 inch collet chucks, end mill holders, and shrink-fit toolholders on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, de-energized state before changing tooling. Seat the 1\/2 inch shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use, and verify runout with a dial indicator when tolerances are critical.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 29\/64 inch (0.4531 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5 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\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\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: Stub\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\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\u003eExtended Reach\u003c\/strong\u003e: No\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: 12182916\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738452263218,"sku":"12182916","price":90.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae59242d255e166590c06f4d1c3c89c3.jpg?v=1788799677","url":"https:\/\/voomisupply.com\/products\/accupro-12182916-square-end-mill-29-64-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
