Let QT TOOLS tell you what is Variable Helix Carbide End Mill?

A variable helix carbide end mill is a type of cutting tool that has a variable helix angle along the length of the flutes. A helix angle is the angle between the axis of the end mill and the edge of the flute. A variable helix carbide end mill is designed for machining a variety of steels, especially hard and tough materials.

The main advantage of a variable helix carbide end mill is that it reduces harmonics and chatter, which are unwanted vibrations that can cause noise, tool wear, and poor surface finish. By varying the helix angle, the end mill can create different cutting forces and frequencies at different points of contact with the workpiece, thus breaking up the resonance and damping the vibration.

Another benefit of a variable helix carbide end mill is that it increases material removal rates, which means it can cut faster and deeper than a conventional end mill. The variable helix geometry allows the end mill to have more effective cutting edges and better chip evacuation, thus reducing heat generation and tool deflection.

A variable helix carbide end mill also enables you to achieve a high level of surface finish without sacrificing tool life. The variable helix geometry reduces the scallop height, which is the distance between adjacent peaks on the machined surface. A lower scallop height means a smoother surface and less need for secondary operations.

A variable helix carbide end mill is made of solid carbide, which is a hard and wear resistant material that can withstand high temperatures and pressures. Carbide end mills are coated with various materials to enhance their performance and durability. Some common coatings are titanium aluminum nitride (TiAlN), aluminum titanium nitride (AlTiN), titanium nitride (TiN), and uncoated.

A variable helix carbide end mill has a square, corner radius, or ball end for milling different shapes and features. It also has a number of flutes, which are the cutting edges on the end mill. The number of flutes affects the chip load, feed rate, and surface finish. Generally, end mills with fewer flutes provide better chip clearance and faster cutting, while end mills with more flutes provide finer finish and smoother cutting.

A variable helix carbide end mill is a versatile and high performance tool that can be used for roughing and finishing operations in various industries, such as aerospace, automotive, medical, mold and die, and general engineering.

Here QT Tools have variable helix carbide end mill For cast iron, carbon steel, mould steel or For Aluminum. The most important is the Unequal spiral design can well suppress the vibration generated in the machining process. Compared with ordinary milling cutter, unequal spiral design supports high-speed cutting and large feed cutting, so as to improve machining efficiency and productivity and effectively save machining cost.
