3 Useful Tips for Insert Carbide Blades

At present, carbide blades have penetrated into various fields, especially in the woodworking cutting process.

Alloy carbide blades are widely used in wood turning, planing, trimming, profiling, grooving, hollowing, etc., and can be seen almost everywhere.

They play an important role in woodworking projects, being in direct contact with the workpiece surface. It is especially important to learn how to choose a woodworking blade to make the surface of the workpiece smooth and clean.
In this article, we will discuss our indexable carbide inserts so that you have a detailed, complete reference when choosing a carbide insert.

What are carbide inserts?

Carbide inserts are made of tungsten carbide, offering more possibilities for a variety of applications.
Tungsten carbide is a chemical composite consisting of tungsten carbide (WC) powder and a binder (usually cobalt) and is the second hardest material in the world.

Because tungsten carbide is extremely hard, it can handle hard and abrasive materials. In addition, tungsten carbide has excellent wear resistance and high temperature resistance compared to steel, allowing for faster processing speeds. As a result, tools made from carbide typically have very sharp cutting edges that produce a smoother, cleaner finish on the workpiece.

Applications of carbide blades

Carbide blades can be installed on the cutterheads of various machines, such as planers, planers, forming machines, edge banding machines, etc.

Unlike traditional milling cutters with carbide cutters brazed to the head, disposable inserts come in handy when one cutting edge becomes dull or damaged and we can replace it with a new insert instead of throwing away the drill bit, leaving The cutterhead improves the service life of the cutterhead while maintaining cutting performance.

At the same time, carbide inserts can also flip the cutting edge according to different specifications, which is why this type of insert is also called a flip insert. For example, a blade with specifications of 15mm*15mm*2.5mm has four cutting edges. When one cutting edge becomes dull, it can be flipped to another cutting edge of the same blade and continued to be used, which is very cost-saving.

Common woodworking carbide blades

There are basically three shapes of woodworking blades: square/rectangular, round and diamond. The square is the most commonly used, and the diamond is less commonly used.
Round inserts for wood turning

Round carbide woodworking knives are sharpened on a diamond grinding wheel to provide a smooth surface on concave and hollow jobs. The general specifications we provide are: R- Φ8.9*1.85mm 30°, R- Φ12*2.5mm 30°, R- Φ15*2.5mm 30°, R- Φ16*3mm 30°.

Rectangular blade
Suitable for various cutter heads such as grooving knives, multi-function knives, planers and spiral planers. It can be used on softwood, hardwood, MDF, solid surface and micro finishing.

Blades of different shapes and numbers of holes can vary greatly in their use and performance in woodworking. You can choose according to your needs. If you are not sure what kind of blade is suitable for your tool, please feel free to consult us. We can provide the most professional advice and high-quality blade products.
