{"product_id":"bc2055-dlc-corner-radius-end-mill-aluminum","title":"BC2055 3-Flute DLC Corner Radius End Mill for Aluminum | Solid Carbide","description":"\u003cp\u003e\u003cstrong\u003eBC2055\u003c\/strong\u003e is a 3-flute, DLC-coated solid carbide corner radius end mill developed for aluminum alloys and other compatible non-ferrous materials. It is a strong choice when chip evacuation, low material adhesion, and a more durable cutting corner matter more than simply using a sharp square-end tool.\u003c\/p\u003e\u003ch3\u003eWhy BC2055\u003c\/h3\u003e\u003cp\u003eAluminum machining often becomes unstable when chips are not cleared efficiently or material begins to build up on the cutting edge. BC2055 addresses that with an open 3-flute geometry and a low-friction DLC-coated surface. The corner radius adds strength at the tool tip, helping the cutter handle contouring and side-milling work with less risk of corner damage than a sharp square end.\u003c\/p\u003e\u003ch3\u003eBest Suited For\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAluminum alloys\u003c\/li\u003e\n\u003cli\u003eCopper and other compatible non-ferrous metals\u003c\/li\u003e\n\u003cli\u003ePlastics and similar materials where a low-friction cutting surface is useful\u003c\/li\u003e\n\u003cli\u003eSide milling and contouring\u003c\/li\u003e\n\u003cli\u003eSemi-finishing and finishing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhen to Choose a Corner Radius\u003c\/h3\u003e\u003cp\u003eChoose BC2055 when the part geometry allows a radius at the internal corner and you want a stronger cutting edge than a square end mill. The selected R value should match the part requirement; a larger radius generally gives a stronger corner, while a smaller radius follows tighter geometry.\u003c\/p\u003e\u003ch3\u003eHow to Choose the Variant\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting diameter:\u003c\/strong\u003e match the feature size and required tool rigidity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner radius:\u003c\/strong\u003e match the drawing and required edge strength.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting length:\u003c\/strong\u003e use only as much flute length as the machining depth requires.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall length:\u003c\/strong\u003e use the shortest practical reach to preserve rigidity and reduce vibration.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eImportant\u003c\/h3\u003e\u003cp\u003eBC2055 is focused on non-ferrous machining.
