45HRC 4 Flutes Flat End Mill

This 45HRC 4 flutes flat end mill is made of high quality carbide with excellent hardness, toughness and wear resistance for long service life. It has a Rockwell hardness scale of at least 45HRC, so it ensures optimum performance even in demanding applications such as high temperature and pressure. Its 4-flute design has 4 flutes strategically placed around the circumference of the cutter with a helix angle of 35-45 degrees. This configuration allows the mill to cut material more efficiently because the flutes evacuate chips and debris more effectively, reducing the chance of clogging or damage. Also, this design allows for higher feed rates, faster cut times and smoother surface finishes. Additionally, this mill features a TiAlN (Titanium Aluminum Nitride) coating that provides superior hardness, wear resistance and oxidation resistance. The coating also reduces friction and heat buildup, improving tool life and cutting performance. Welcome customers in need to come to discuss cooperation with us!

Features

1. The cutting edge of this flat end mill is flat so it can make precise cuts and create flat bottom features such as slots, grooves and cavities. This design also ensures that the contact area between the tool and the workpiece is maximized, reducing the possibility of chatter, vibration or deflection.

2. This flat end mill has a lot of versatility and is very cost-effective as it can be used to machine a variety of materials including aluminum, copper, alloy steel and stainless steel.

3. This high-hardness 45HRC 4 flutes flat end mill is made of cemented carbide, so that it can better resist wear and deformation, and maintain long-term cutting quality.

4. Its flat head design can be applied to a variety of processing needs, such as face milling, inclined face milling, processing edges and corners, etc. Therefore, it can be used to process a variety of workpiece structures, such as molds, construction machinery, auto parts, etc.
