Built from micrograin carbide and coated with AlCrTiN for heat and wear resistance, this tool handles high-speed cutting in ferrous and hardened materials. It features a variable helix and variable index geometry that reduces harmonic vibration and chatter during aggressive cuts. With a 1\/4 inch cutting diameter, 3\/4 inch length of cut, and 2-1\/2 inch overall length, it fits standard tool holders and collets used across vertical machining centers and CNC mills. This is a single-end, right-hand cut, right-hand flute tool suited for machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is well suited for finish and semi-finish milling operations in steel, stainless steel, and high-temperature alloys where tool life and surface finish matter. The straight cylindrical shank with h6 tolerance ensures a precise, repeatable fit in precision collets and end mill holders. The long length type provides additional reach in deeper pocket or slot applications while maintaining rigidity. Machinists working in job shop, production, or aerospace environments will find this geometry effective for slot milling, profiling, and contouring passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlCrTiN coating provides high-temperature oxidation resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduces vibration and chatter for improved surface finish\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate offers superior hardness and wear resistance compared to standard carbide grades\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation for use in standard CNC and manual milling setups\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with h6 shank diameter tolerance for precision tool holder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling option for 1\/4 inch straight shank collets, end mill holders, and shrink-fit holders used in CNC vertical machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with CNC or manual milling equipment. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the collet or holder bore is clean and free of chips before seating the shank. Follow the tool manufacturer and machine tool builder guidelines for runout verification and minimum shank engagement depth.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\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: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (2-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.040 \/ -0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrTiN\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\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\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches (0.08 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 95172690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728443277618,"sku":"95172690","price":75.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/439687a992dd47d5f7204e0f2f2fdf09_6c6161a9-4cff-4831-b485-18ed8269bfbd.jpg?v=1788691252","url":"https:\/\/voomisupply.com\/products\/accupro-95172690-square-end-mill-1-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
