How to choose the correct four-sided planer blade

When using a four-sided planer, factories typically have two options: square four-sided blades or rectangular double-sided blades. How should you choose the right blades for your needs?  Below, I will explain based on my experience.

Square-shaped blades are the most commonly used blades in four-sided planers. As the name suggests, all four edges of the blade can be used, which is its biggest advantage. When one edge becomes dull, the other three edges can be used, significantly saving costs.  Square blades are typically small in size and suitable for relatively soft woods.

If planing hard wood, rectangular blades should be chosen. Rectangular blades are larger than square blades, making them more durable. However, rectangular blades only have two usable edges. There are also many types of blade materials on the market, the most common of which are two: alloy material and diamond material. Diamond blades have a longer service life than alloy blades, but the price of diamond blades is very expensive, and the cost of grinding diamond blades is also very high.
