The cutter measures 3\/8 inches in diameter with a 7\/8-inch length of cut and a 2-1\/2-inch overall length. It features three spiral flutes with a 40-degree helix angle and an AlTiN (aluminum titanium nitride) coating that improves heat resistance and extends tool life in high-speed cutting operations. The micrograin carbide substrate provides hardness and wear resistance suited to ferrous and non-ferrous workpieces. This end mill is center-cutting, allowing direct plunge entry into material. It is typically installed and run by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits milling operations on steel, stainless steel, cast iron, and similar materials where a right-hand spiral, right-hand cut tool is required. The regular-length configuration and 3\/8-inch shank make it compatible with standard collets, ER chucks, and end mill holders found on vertical machining centers and CNC mills. The 40-degree helix promotes efficient chip evacuation and reduces chatter during peripheral and slotting cuts. It is a single-end tool intended for conventional and climb milling in both roughing and finishing passes where a square shoulder profile is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish improves heat resistance in high-speed and dry cutting applications\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eThree-flute geometry balances material removal rate with chip clearance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8-inch collets, ER chucks, or end mill holders on vertical machining centers and CNC milling machines where a right-hand, spiral-flute square end mill is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the holder to the recommended gauge-line depth and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with an indicator before beginning cuts, and confirm cutting parameters against the workpiece material and machine capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inches (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: AlTiN\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 12179727\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737799721266,"sku":"12179727","price":67.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0641a72a1c7682e272b0d21845552a9d.jpg?v=1788793695","url":"https:\/\/voomisupply.com\/products\/accupro-12179727-square-end-mill-3-8-inch-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
