Measuring 29\/64 inches (0.4531 inches) in diameter with a 1 inch length of cut and 3 inch overall length, this tool is built for consistent performance in tight-tolerance work. The micrograin carbide substrate provides wear resistance, and the AlTiN coating extends tool life in ferrous and high-temperature alloy materials. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Machinists and tool-and-die professionals working in job shops, production environments, and maintenance machining specify this tool for slotting, profiling, and contouring operations.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard 1\/2 inch shank toolholders including collet chucks, end mill holders, and shrink-fit holders found on vertical machining centers and CNC mills. Its centercutting geometry allows direct plunge entry into workpiece material, expanding its usefulness in pocket milling and ramp-entry operations. The right-hand cut and right-hand spiral flute configuration is the standard orientation for conventional and climb milling on CNC and manual mills. The regular-length body suits the majority of general-purpose milling tasks where extended reach is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN finish improves heat resistance and extends tool life in ferrous alloys\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for efficient chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling and pocket entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute — standard CNC mill orientation\u003c\/li\u003e\n\u003cli\u003e29\/64 inch diameter with tight mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 1\/2 inch shank toolholders on CNC vertical machining centers and manual knee mills.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify proper tool stick-out and runout with a dial indicator before cutting. Follow shop safety standards and machine manufacturer guidelines for speeds and feeds appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish \/ Coating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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: 0.25 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: 12181451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744911819058,"sku":"12181451","price":96.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfa37591dbf7bae5d800a2f8c1da81b7.jpg?v=1788862115","url":"https:\/\/voomisupply.com\/products\/accupro-12181451-square-end-mill-29-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
