YG-1 E5104 Carbide Corner Radius End Mill, Weldon Shank, TIALN Multilayer Finish, Non-Center Cutting, 35 Deg Helix, 3 Flutes, 2.75' Overall Length, 0.4375' Cutting Diameter, 0.4375' Shank Diameter, 0.030' Corner Radius: Industrial & Scientific. YG-1 E5104 Carbide Corner Radius End Mill, Weldon Shank, TIALN Multilayer Finish, Non-Center Cutting, 35 Deg Helix, 3 Flutes, 2.75" Overall Length, 0.4375" Cutting Diameter, 0.4375" Shank Diameter, 0.030" Corner Radius: Industrial & Scientific. Corner radius end mills have cutting edges with rounded corners to reduce chipping and provide longer tool life . Suitable for high-performance slotting, ramping, and pocket machining on stainless steel and steel alloys up to Rockwell hardness C35 . 35-degree helix angle provides increased cutting action and chip evacuation compared to the standard 30-degree helix . Titanium aluminum nitride (TiAlN) coating lubricates the end mill for high-temperature stability and abrasion resistance at high cutting speeds, offering better heat resistance than uncoated finish and TiN and TiCN coatings . Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting . The E5104TF TiAlN-coated carbide corner radius end mill has a 35-degree helix angle, three flutes, and a center-cutting design for high-performance slotting, ramping, and pocket machining on stainless steel and steel alloys up to Rockwell hardness C35. Corner radius end mills have a square end with rounded corners on the cutting edges to reduce chipping and extend the life of the tool. The 35-degree helix angle provides more support behind the cutting edge than higher angles, and increases cutting action and chip evacuation compared to the standard 30-degree helix. It efficiently cuts difficult-to-machine material, moving it up the spiral and away from the workpiece. The end mill’s three flutes provide better chip-carrying capacity than four flutes and a finer finish than two. They efficiently remove excess material from the cutting area and provide a third cutting edge to create an improved finish that may eliminate the need for a second finishing cut in some applications. The center-cutting design has cutting teeth at the end of the tool, so it can be fed into the workpiece like a drill bit. . The TiAlN coating resists heat better than TiN and TiCN coatings, increasing tool life and performance. It also offers increased hardness compared to TiN and may reduce the need for lubricants based on the application. The carbide substrate is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. Cutting diameter tolerance is + 0.000 to - 0.0012". The tool has a Weldon shank. . End mills are designed to remove material and create multi-dimensional shapes and profiles. They have cutting edges along the outside diameter and flutes that remove chips from the cutting area and allow cooling fluids to enter. If heat is not reduced effectively, the tool’s cutting edges will dull and additional material buildup can occur. The number of flutes can range from two to eight. Two-flute designs offer the most efficient chip removal, but more flutes provide a smoother finish. The shank is the end of the tool held in place by a tool holder or machine. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. Non-center-cutting end mills are for applications such as peripheral milling and finishing, but cannot make plunge cuts. . manufactures drills, taps, end mills, and rotary tooling.
