How to choose a right type carbide insert knife for planers or jointers?

The cutting process of woodworking tools is an extremely complicated process. In the high-speed cutting process, the processed wood is deformed due to its own properties (wood fiber, growth ring direction, wood type, moisture content, temperature, etc.), tool characteristics (cutting angle, Sharpness) and cutting parameters (cutting depth, cutting speed, feed rate) and other factors.

The principle of selecting the blade is mainly for the nature of the planing material, wood type, planing thickness, etc. Applicable for light cutting: 14*14*2.0mm /15*15*2.5mm carbide indexable inserts

Suitable for heavy cutting: 30*12*1.5mm carbide blade, of course, 14*14*2.0mm and 15*15*2.5mm carbide insert knives can also be used for heavy cutting models, which can be selected according to different types of processed parts.

The spiral cutterhead for heavy-cutting has a larger planing thickness, generally the maximum planing thickness can reach 8mm; the spiral cutterblock for light-cutting has a smaller planing thickness, and the general maximum planing thickness can reach 5mm. When the planing amount needs a large depth When planing, a heavy-cut with 30*12*1.5mm rectangular straight insert knife can be used. Of course, when the planing thickness is not very large, and the workpiece is difficult to plan, the square carbide insert knives with 14*14*2.0mm and 15*15*2.5mm are applicable.


The advantages of ToolingBox carbide insert knives:

  • The Blade surface with spiral: the high-precision design and manufacturing technology arranges the discarded blades rationally around the blade body to form a smaller cutting surface per unit time to improve blade burn marks and cutting edges.

  • Longer service life: if you use a spiral cutterhead with an aluminum alloy body, you can get a better tool life of 1-2 times longer than that of a general flat blade. If it is used for double-sided planer and four-sided planer, the tool life will be 3-4 times longer.

  • Sawdust is very small: cutting with a spiral model during unit time, the formed sawdust is very small, and it is easy to remove the sawdust from the surface of the processed wood in the special dust collection system.

  • Low noise: the noise value generated by contacting the wood surface and the flat blade in the same time when the wood surface is in contact with the wood surface per unit time is reduced by approx. 30 to 50dB.
