The tool features a 0.25-inch cutting diameter, a 1.125-inch length of cut, and a 3-inch overall length. Constructed from micrograin solid carbide, it delivers rigidity and edge retention that general-purpose high-speed steel tooling cannot match. The nACRo finish reduces friction and improves heat resistance during aggressive cuts. This is a centercutting tool, meaning it can be plunged directly into the workpiece. Machinists and tool-and-die professionals use it in CNC machining centers and manual mills where tight tolerances and fine surface finish are required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and plunge-cutting applications in shop environments running ferrous alloys, aluminum, and plastics. The 2-flute configuration provides adequate chip clearance in slotting passes where flute pockets need to evacuate material efficiently. The 40-degree helix angle promotes smooth cutting action and reduces chatter on both roughing and light finishing passes. The 0.25-inch shank diameter fits standard 1\/4-inch collets and end mill holders commonly found in ER-style and straight-bore tooling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003enACRo finish reduces heat buildup and extends tool life in high-speed cuts\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute configuration for standard spindle use\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry provides maximum chip clearance in slotting applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cutting tool compatible with standard 1\/4-inch collets and end mill holders in CNC machining centers and manual vertical mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with cutting tool mounting procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism to the toolholder manufacturer's specification. Verify runout with a dial indicator before initiating a cut to avoid premature tool wear or workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eLength of Cut\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: nACRo\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\u003eExtended Reach\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 12178815\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":67913252569394,"sku":"12178815","price":73.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa671b2b9414d9bacd0bbe0999539093_4875964a-295e-46b2-b577-2a8ee2022df1.jpg?v=1791243900","url":"https:\/\/voomisupply.com\/products\/accupro-12178815-square-end-mill-1-4-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
