BB® Tungsten Steel Solid Carbide End Mills

Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid tool-holding systems.

Dementions

Tolerance of End Mill Diameter:
1 < D≤6 -0.010 ~ -0.030
6 < D≤10 -0.015 ~ -0.040
10 < D≤ 20 -0.020~-0.050

Industrial Design

Negative front angle and large chip space.Easier roughing and finishing processing.
Decreasing the times of changing cutters,Saving production time.

Helix Angle:35 deg, high adaptability to the material and hardness of workpieces, widely used to mold and product processing and cost efficient.

Coating:Good coating can improve tools life and production efficiency, as well as solve the cutting problems.

Application

Used in Milling Machine.,CNC,Drill press,Engraving machine. Metal, woodworking, alloy steel, stainless steel, etc

BB 2 flutes end mills is widely used in slotting, sinking etc.
3 flutes for aluminum，non-ferrous metal.
4 flutes, high rigidity, widely used in shallow slot, profile milling, and finish machining.

BB® BK2045 Carbide End Mills

Color: Dark grey.
Density: 14.5 g/cm3
Hardness: HRA 91.5
Grain Size: 0.8um
Bending Strength: 2800N/mm2
Raw material: Recycled material,YG10X with 10% Co content and 0.8um grain size. Because tungsten is a scarce resource, BK2045 series milling cutter is made of recycled tungsten steel.

Coating: ALTiN,High aluminum content provides excellent hot hardness and oxidation resistance.
A good choice for milling general steels weaker than HRC 30.
But, because of the aluminum content, it is not good choice for aluminum.
