What is the difference in the use of the replacement woodworking spiral cutter shaft with 14, 15, and 30 blades?

With 14x14x2.0mm blade light-duty woodworking spiral cutter shaft

Advantage:

The cutter shaft is produced by five-axis linkage processing, with high precision, and with high-precision blades and screws, the accumulated tolerance can be reduced to a minimum.
The contact surface of the workpiece processed by the tool is only 14mm per unit time in the spiral arrangement, so that the power of the entire woodworking machine and the entire knife is concentrated on a small surface, and the planing effect is close to the extreme.

Precautions:

Limited by the strength of the 14x14x2.0 blade, the cutter shaft with 14x14x2.0 blade is only suitable for planing below 5mm.

When the humidity of the wood is too high, it is easy to cause chip blocking, which reduces the effective contact between the blade and the processed material, and causes the blade to chip.
With the same length, the number of blades is large, and it takes time to install the blades.

With 15x15x2.5mm blade light-duty woodworking cutter shaft

Advantage:

The cutter shaft is produced by five-axis linkage processing, with high precision, equipped with high-precision blades and screws, and the accumulated tolerance can be reduced to a minimum.

Spiral arrangement unit time, the contact surface of the tool processing workpiece is only 15mm, so that the power of the entire machine and the entire knife is concentrated on a small surface, and the planing effect is close to the extreme.

Precautions:

With the same length, the number of blades is large, and it takes time to install the blades.

With 30x12x1.5mm blade heavy-duty woodworking cutter shaft

Advantage:

　The pressure block design increases the stability of the tool. The groove spiral chip removal design can effectively remove the chips and facilitate the heat dissipation of the tool.

　 Spiral arrangement unit time, the contact surface of the tool processing workpiece is only 75px, so that the strength of the entire machine and the entire knife is on a small surface, and the planing effect is close to the extreme.

　The number of blades under the same length is less, which can save the time of blade changing.
