Advantages and disadvantages of double-sided woodworking saw blade

The invention has the advantages that it is designed and manufactured according to the cutting characteristics of wood, and can be used for cutting various hard and soft solid wood and various artificial boards. The disadvantage is that it is easy to wear.

There are several standards to judge the quality of saw blades.

Look at the size of the saw blade tip: the tungsten steel tip of the woodworking saw blade with better quality is often thicker, so that the grinding times of the saw blade can be slightly more; Welding seam of flip-chip explosive welding: For a woodworking saw blade with dozens of teeth and good quality, the welding seam between each cutter head and the saw blade steel plate (saw blade matrix) is thin and uniform. If it is electroplated saw blade matrix, the trace caused by high welding temperature will not be obvious for the saw blade with good welding effect.

Grinding marks on turning head: This requires people with good eyesight to see that the grinding marks on the blade head with good quality are even and delicate; Look at the expansion groove and silencing line of the saw blade: the design of low-grade saw blade on the cooling groove is relatively simple, and there is often no silencing line design; Tap the steel plate of the saw blade: When the saw blade is suspended, tap the steel plate at the same position with the same force. The better saw blade makes a lighter sound, while the lower saw blade makes a louder sound-some are more lasting and even have vibrato.
