Built to stub-length proportions, it offers increased rigidity in applications where tool deflection and chatter are concerns. The cutting diameter measures 0.2756 inches with a 0.4724-inch length of cut, and the shank diameter is 0.3150 inches. The four-flute, right-hand spiral geometry runs at a 40-degree helix angle, promoting efficient chip evacuation and smooth cutting action. The micrograin carbide substrate supports the higher speeds and feeds typical of modern CNC milling centers. This tool ships uncoated and is centercutting, allowing plunge entry into workpieces.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slot milling, profiling, and peripheral milling in a range of shop environments, from job shops running general-purpose work to production facilities handling tighter-tolerance components. The stub length configuration makes it a strong choice for setups with limited Z-axis clearance or where maximum rigidity is required to hold dimensional tolerances. It is compatible with standard 8 mm collets or end mill holders accepting a 0.3150-inch shank. CNC machining centers and manual knee mills with appropriate toolholding are typical use environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand spiral geometry with 40-degree helix angle\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eStub length for maximum tool rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with cutting fluids on a broad range of materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard end mill holders or collet chucks accepting a 0.3150-inch shank diameter.

Secure the shank fully within the toolholder to the manufacturer-recommended gauge length before tightening. Verify runout with a dial indicator before beginning a cut. Follow the machine tool manufacturer and cutting tool supplier recommendations for speeds, feeds, and depth of cut appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2756 inches (7.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.4724 inches (12.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 63.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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: 0.06 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: 12182820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749504319794,"sku":"12182820","price":60.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eef400a4b32f8422b3a704527040507f.jpg?v=1788906947","url":"https:\/\/voomisupply.com\/products\/accupro-12182820-square-end-mill-0-2756-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
