With a 3\/16 inch (0.1875 inch) mill diameter and a 0.060 inch corner radius, this tool produces smooth, radiused edges on workpiece corners, reducing stress concentrations and improving surface finish. The 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces. A TiCN (Titanium Carbonitride) coating increases surface hardness and wear resistance, extending tool life across a range of ferrous and non-ferrous materials. This end mill is intended for use by machinists and CNC operators in production shop and job shop settings.\u003c\/p\u003e\u003cp\u003eThis tool suits applications requiring extra-long reach, with a 1-1\/8 inch length of cut and a 3 inch overall length. The single-end, centercutting design allows plunge cutting in addition to peripheral and slot milling. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC vertical and horizontal milling setups. The micrograin carbide substrate supports consistent performance in tight-tolerance work where dimensional accuracy is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.060 inch corner radius reduces stress risers and improves part finish on radiused profiles\u003c\/li\u003e\n\u003cli\u003eTiCN coating provides elevated surface hardness and extended tool life on hard materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes aggressive chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eExtra-long length of cut (1-1\/8 inches) allows reach into deep pockets and slots\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers dimensional stability under high feed rates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill suitable for standard 3\/16 inch collet or end mill holder setups on CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder tightening and runout verification. Confirm the spindle and toolholder are clean and free of debris before seating the shank. Always power down and lock out the machine before changing tooling. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches (1.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\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 (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 12183217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748188651826,"sku":"12183217","price":66.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d5702321fcb73c1d329c3cbaaf21c1a_7f6ad533-4cdd-4d13-8cb6-32d95f6264fb.jpg?v=1788890097","url":"https:\/\/voomisupply.com\/products\/accupro-12183217-corner-radius-end-mill-3-16-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
