Built from micrograin carbide stock and finished with a TiCN (Titanium Carbonitride) coating, this tool delivers extended wear resistance and thermal protection compared to uncoated alternatives. It features a 0.25-inch cutting diameter, a 1.5-inch length of cut, and a 4-inch overall length that qualifies it as an extra-long configuration. The 40-degree spiral helix angle promotes efficient chip evacuation and smooth cutting action. Machinists and CNC operators working with ferrous metals, alloys, and hardened materials will find this end mill well suited to slotting, profiling, and contouring operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical and horizontal milling machines as well as CNC machining centers where a 0.25-inch straight shank is accepted. The extra-long overall length makes it appropriate for applications requiring extended reach into deep pockets or tall workpiece features. The centercutting geometry allows plunge entry directly into the workpiece, eliminating the need for a pre-drilled pilot hole in most operations. Right-hand cut and right-hand flute orientation are standard for conventional spindle-up milling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for high rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves surface hardness and reduces tool wear at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes aggressive chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e3-flute configuration balances chip clearance with cutting edge strength\u003c\/li\u003e\n  \u003cli\u003eExtra-long 4-inch OAL provides extended reach for deep-pocket and tall-feature work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for any milling machine or CNC machining center equipped with a 0.25-inch shank collet, end mill holder, or compatible tool-holding system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before changing tooling. Seat the shank fully into the collet or holder to the minimum insertion depth recommended by the toolholder manufacturer before torquing the drawbar or collet nut. Verify runout with a dial indicator after mounting, as excessive runout will accelerate edge wear and reduce surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: 1.4 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: 12182242\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729545855282,"sku":"12182242","price":59.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ef7bb78017cda5a6b3242ddf66f1483.jpg?v=1788705984","url":"https:\/\/voomisupply.com\/products\/accupro-12182242-square-end-mill-1-4-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
