With a 0.25 inch mill diameter and a 1.5 inch length of cut, this tool handles slotting, profiling, and peripheral milling in demanding materials. The TiCN (titanium carbonitride) coating improves surface hardness and wear resistance compared to uncoated carbide. The micrograin carbide substrate supports higher cutting speeds and finer edge retention. At 6.0 inches overall length, this is an extra-long configuration suited for deep-reach operations where standard-length end mills cannot access the workpiece. Licensed machinists and CNC operators are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill fits common CNC machining centers, vertical mills, and manual milling machines accepting a 0.25 inch shank. The extra-long 6.0 inch OAL makes it appropriate for deep-cavity milling, mold and die work, and applications requiring extended reach into pockets or fixtures. The centercutting geometry allows plunge entry directly into the workpiece. Right-hand cut and right-hand flute configuration is standard for conventional spindle rotation in most machining setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN finish for increased wear resistance and reduced friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge sharpness and rigidity at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration balances material removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003eExtra-long 6.0 inch OAL provides deep-reach capability for cavities and hard-to-access features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual milling machines with a 0.25 inch collet or tool holder accepting a 0.25 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the tool holder. Use a properly sized collet or end mill holder and verify runout with a dial indicator before cutting. Follow the tooling manufacturer and machine manufacturer guidelines for appropriate feed rates and spindle speeds based on workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\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: Extra Long\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\u003eWeight\u003c\/strong\u003e: 0.12 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: 12183644\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732979351858,"sku":"12183644","price":80.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4cce3fd3a184483174394417e544d000.jpg?v=1788749910","url":"https:\/\/voomisupply.com\/products\/accupro-12183644-square-end-mill-1-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
