When it comes to selecting carbide insert knives for wood inserts for woodworking tools, you have several options. For instance, you can choose between C3 or the KCR08, or you can choose between the KCR10 or KCR12. The selection of a carbide insert depends on the orientation of the tool and the job site conditions. The sixth code, which refers to the full width of the shank, will also guide you in choosing the correct carbide knife for the job.
C3
Solid C3 carbide insert knives are available in dozens of standard sizes for a wide variety of woodworking applications. These long-lasting inserts are polished to a mirror finish for smoother cutting and extended tool life. If you are in the market for a new cutter, you can try a new C3 carbide insert knife, as it is a highly affordable and effective way to increase your woodworking productivity.
While all carbide is made from the same basic ingredients, the quality of the carbide material will affect the performance of the tool. The hardness of the carbide matrix is determined by the C grade of the material. C2 carbide is not as hard as C3 carbide, while C4 carbide is a step above. Although harder, C4 carbide will produce a better finish, but it will be brittle and susceptible to shattering.
KCR08
If you are in the market for carbide insert knives for woodworking, you have probably come across the KCR08 grade. These knives have been designed for woodworking and can reduce the frequency of tool changes and enhance overall efficiency. They are also compatible with your existing HC05 reversible knives. Here are some of the benefits of these carbide knives:
Chemical corrosion is a common problem with carbide inserts. This corrosion process allows hard tungsten particles to leach out, creating a dull cutting edge. This wear is further enhanced by higher cutting temperatures. CERATIZIT has developed a new corrosion resistant Chrome binder to overcome this problem. Chrome replaces cobalt as the primary binder. This improves the price-performance ratio of these carbide insert knives.
KCR10
The increased cutting performance of the KCR10 carbide insert knife is the result of submicron tungsten particles and improved process reliability. Submicron grain structure means fewer tungsten particles are affected by cutting chemicals, air moisture, and grinding lubricants, ensuring a more consistent cutting edge. Both of these factors reduce the likelihood of premature tool wear and minimize the quality of the component cut.
The improved hardness-to-fracture toughness properties of the KCR08 grade are a result of the optimized binder system. This results in an increased cutting edge that resists impact for longer than a conventional grade. This improved chip-resistance makes the tool last longer and improves the cut quality. The improved performance of KCR08 carbide insert knives makes it a desirable choice for any manufacturer of woodworking tools.
KCR12
Solid carbide insert knives are made from micro-grain carbide, and are available in dozens of standard sizes. They have one, two, or four wear edges, and they don’t need sharpening. They also have a unique design that allows the new carbide insert to be quickly and easily fastened into the body of the tool, maintaining its profile. If sharpening isn’t your main priority, you can try a new one by sharpening the blade first, and then replacing the old one with a new one.
KCR19
Carbide insert knives are commonly referred to as turnable or tungsten carbide turnover knives. They are available in dozens of standard sizes. They have one, two, or four wear edges, depending on the size and shape. The new carbide insert is quickly and easily fastened to the tool’s body and retains its profile. Because they are made from tungsten carbide, they are durable, rust-resistant, and require no sharpening.
The submicron grain structure of carbide allows the insert to run at higher speeds. This enables the machine to process the workpiece faster, which leads to better finishes. Carbide inserts can cause a host of issues if not chosen correctly. Incorrect carbide insert selection can ruin the knife, the machine, or the workpiece. To avoid this problem, carbide inserts are identified using the Turning Tool ISO code system.
