The tool measures 7\/16 inches (0.4375 inches) in diameter with a 1 inch length of cut and a 2-3\/4 inch overall length. Three right-hand spiral flutes with a 35-degree medium helix angle promote efficient chip evacuation and stable cutting across a range of workpiece materials. An AlTiN PVD coating enhances heat and wear resistance, extending tool life in demanding machining environments. This single-end mill is suited for CNC machining centers and manual milling machines operated by machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThe SB335 series ball end mill is built for short-length applications where rigidity is critical. The 7\/16 inch Weldon flat shank provides secure tool holding and minimizes runout, with a maximum TIR of 0.0005 inches. The centercutting geometry allows plunge entry, making it suitable for profiling, contouring, slotting, and 3D surface work in steel and cast iron as well as aluminum and non-ferrous alloys. It is well suited to production environments where consistent dimensional accuracy is required across repeated operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in metal cutting\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating rated for elevated temperatures in steel and cast iron applications\u003c\/li\u003e\n\u003cli\u003e3 right-hand spiral flutes with 35-degree medium helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank reduces tool pullout risk during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eCompatible with steel, cast iron, aluminum, and non-ferrous workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC and manual milling equipment with standard 7\/16 inch tool holders or Weldon-flat-style collet chucks.
