Package Included: 5pcs 1/2" carbide square end Mill.
Material: Made of micro grain carbide. Carbide has higher hardness and wear resistance and excellent cutting performance than high-speed steel..
Coating: AlTiN, high aluminum content provides excellent hot hardness and oxidation resistance..
HRC 45 deg :carbide end mill tools excel at working carbon steels (~ HB225), alloy steels (HB225 ~ 325), pre-hardened steels (up to HRC45), hardened Steels (HRC40 ~ 45), cast iron..
Flutes:4 Flutes,high rigidity ,widely used in shallow slot,profile milling,and finish machining..

Corner radius end mills have cutting edges with rounded corners to reduce chipping and provide longer tool life.
Four flutes produce a better finish than fewer flutes.
Carbide can run at higher speeds than high-speed steel, resisting abrasion and high cutting temperatures.
Titanium aluminum nitride (TiAlN) coating lubricates the end mill for high-temperature stability and abrasion resistance at high cutting speeds.
Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling.

Ball Noze type,1/8" Shank X 1/8"Cutting Dia, 17mm Flute Length with 2 Spiral Flutes, Total length 38 mm.
Carbide Ball End mill Router bits are widely used For CNC Engraving, Milling, Roughing, Hollowing, 3D sculpturing purposes.
Due to the Great hardness of solid Tungsten carbide Material, it can easily remove materials like Wood, acrylic, PVC, cooper, aluminum, and steel, MDF, Resin, PCB.
Double Flute Spiral Design Improved the chip removal efficiency, surface mirror finish prevent chips from sticking to bits, which makes cutting more smooth.
