The larger the helix angle of the end mill, the longer the contact line between the workpiece and the blade, the smaller the load applied to the blade per unit length, which is beneficial to the life of the tool. But on the other hand, as the helix angle increases, the axial component of cutting resistance also increases, making the tool easy to fall off from the tool holder. Therefore, when machining with a tool with a large helix angle, a strong and rigid tool holder is required.

The thermal conductivity of stainless steel is low, which has a great impact on the tool tip. When cutting difficult-to-cut materials, using an end mill with a large helix angle is beneficial to the tool life. For high-hardness workpieces, as the hardness increases, the cutting resistance will increase. End mills with large helix angles are beneficial to tool life.

On the other hand, choosing a tool with a large helix angle will easily cause an increase in cutting resistance. For right-hand spiral tools, the cutting resistance acts downward on the tool, making the tool easy to fall off. Therefore, it is necessary to adopt a countermeasure of using a tool holder with high rigidity.

Even if the rigidity of the tool is ensured, in cases where the workpiece rigidity is low, such as thin plate processing, an end mill with a small helix angle is sometimes used.

● Efficient cutting performance

The large helix angle milling cutter adopts a large helix angle design, which allows chips to be discharged more smoothly during cutting, reducing chip clogging and the accumulation of cutting force. This design significantly improves cutting efficiency, makes the processing process faster, and greatly shortens the production cycle.

● Excellent chip removal ability

The large helix angle structure of the large helix angle milling cutter not only helps the smooth discharge of chips, but also effectively reduces the heat generated during the cutting process. This helps keep the tool cool, reduces tool wear, and extends its service life. At the same time, good chip removal ability can also reduce vibration and noise during the cutting process and improve processing stability.

● Excellent cutting stability

The large helix angle design makes the milling cutter more stable and balanced during the cutting process. This helps reduce cutting vibration, improve machining accuracy, and reduce workpiece surface roughness. At the same time, the stable cutting process can also reduce the friction between the tool and the workpiece, reduce the cutting force, and further improve the cutting efficiency.

● Wide range of applications

Large helix angle milling cutters are suitable for a variety of materials and processing scenarios. Whether it is metal, non-metal or composite materials, it can show excellent cutting performance. In addition, the large helix angle design allows the milling cutter to maintain stable cutting effects when processing workpieces of different shapes and sizes, meeting various processing needs.

● High durability and long life

Large helix angle milling cutters are made of high-quality materials, precision machined and heat treated, and have excellent wear resistance and impact resistance. This allows the tool to maintain stable cutting performance during long-term, high-load cutting operations and prolongs its service life.
