4Pcs/Lot,Carbide Ball Nose End Mills,2Flute,Coated,Solid Micro Tungsten Grain Carbide CNC TiN Coated Router Bit Spiral Up Cutter (R2.1mm +8.4mm Flute +6mm Shank +50mm OAL)

1.For longer tool life and a better finish in general purpose milling applications,these solid carbide end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel end mills. 2.Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. They have a ball end for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface. 3.End mills with 2 flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; 4.Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs.They’re more wear resistant than uncoated end mills. Titanium-nitride (TiN) coated end mills create less friction than uncoated end mills, which means they last longer when run at similar speeds.
