HRC65 Milling Cutter 4 Flute Solid Carbide Ball Nose Endmills Drill Bit

Special coating techniques make endmills smooth, which leads to low friction and unobstructed chip flow.

Unique coating with Nano structure closely integrates with substrate, ensuring higher hardness and toughness.

Excellent thermal stability and chemical stability can effectively protect cutting edge.

High-performance nano-stucture coating guarantees good toughness and hardness of endmills. Special coating technology guarantees smooth surface and excellent wear resistance.

A multi-functional tool which has cutting edges on the periphery and an end face. Size milling, curved surface milling and drilling are possible only by one tool. These types of milling cutters have the cutting teeth on the both sides. We use end mill more in the vertical milling processes. The high speed steel doesn’t loose its hardness when the temperature increases.

Single Flute - Allows for larger chiploads in softer materials

Double Flute - Allows for better part finish in harder materials

Multiple Flutes - Allows for an even better part finish in harder materials

As the number of cutting edges increases, your feed rate should increase to prevent burning and premature tool dulling. More flutes reduce chip load and improves surface finish if feed rate remains the same. The most common flute numbers for general milling operations are two (better space for chip ejection) and four (better surface finish).

1). High speed machining of hard workpieces materials

Hard cut can be use on workpieces materials that include steel up to 60HRC, High Nickel content alloys and Titanium. Hard cut is particularly suited for carbide endmills and gear cutting tools for semi-finishing and finishing operations that involve high temperatures at the chip/ cutting edge interface. The cutting speed generally range from 100 to 300 m/min, depending on cutting conditions and workpiece material.

2).PVD coating

PVD coating provides for superior control of coating grain size from 10nm to 80nm, achieves excellent hardness , good oxidation resistance and improved reduction of the coefficient of friction.
