Woodworking enthusiasts and professionals both recognize the significance of utilizing appropriate tools for their tasks. When it comes to achieving precise and clean cuts in wood, the circular saw emerges as a favored option. However, the crucial factor in attaining accurate results lies in the careful selection of the suitable circular saw blade. In this article, we will delve into the realm of wood cutting circular saw blades, examining their various types, features, and important considerations. Our aim is to assist you in choosing the perfect blade that aligns with your woodworking requirements.
Types of Wood Cutting Circular Saw Blades
Renowned for their durability and versatility, carbide-tipped blades deliver exceptional cutting performance. The inclusion of carbide tips enables these blades to effortlessly cut through a wide range of materials, including wood, metals, and plastics
High-Speed Steel Blades
If you’re looking for a cost-effective option with excellent heat resistance, high-speed steel blades are the way to go. These blades are particularly suitable for cutting hard wood and are ideal for occasional use or projects with budget constraints.
Essentials About Wood Cutting Circular Saw Blades
When selecting a wood cutting circular saw blade, several factors should be taken into account:
- Blade Diameter and Thickness: The blade diameter directly affects the depth of cut you can achieve. A larger diameter allows for deeper cuts, while a smaller diameter is suitable for shallower cuts. Additionally, the thickness of the blade influences stability and precision during cutting. It’s essential to choose the appropriate dimensions that align with your specific application requirements.
- Number of Teeth: The number of teeth on a blade has a significant impact on both cutting speed and finish quality. Blades with a higher tooth count are ideal for achieving finer cuts that require smooth and precise edges. On the other hand, blades with fewer teeth are better suited for rough cuts, where speed is prioritized over a refined finish.
Types of Cutting Circula Saw Blade Teeth
Alternate Top Bevel (ATB) Teeth
Used for crosscutting various soft and hard woods which requires cutting perpendicular to the wood grain.
Alternate Top Alternate Face (ATAF) Teeth
Similar to regular ATB, it is used for crosscutting various soft and hard woods (cutting perpendicular to the wood grain). However, the AF structure design allows for cutting even harder woods with fine cuts.
Alternate Top Bevel with Rake (ATBR) Teeth
ATBR is a tooth configuration consisting of two sets of ATAF or ATB teeth followed by a flat-top tooth, enabling it to perform both crosscutting and ripping operations on wood materials simultaneously.
High Alternate Top Bevel (HiATB) Teeth
Compared to regular ATB, HiATB has a higher sharpness, allowing it to cut harder wood materials. In addition, it is also used for cutting delicate materials such as plywood, melamine board, and laminates that are prone to damage.
Flat Top Grind (FTG) Teeth
It is commonly used for rapid cutting along the wood grain, also known as ripping. It is suitable for both soft and hard wood materials.
Triple Chip Grind (TCG) Teeth
The high trapezoidal-shaped teeth are used for initial cutting, followed by the reverse trapezoidal-shaped teeth for rapid material removal. This design minimizes the risk of damaging the adhesive on plywood, making it suitable for cutting hard materials, MDF (Medium Density Fiberboard), OSB (Oriented Strand Board), and plastic. TCG blades can also be used for cutting non-ferrous metal materials.
Modified Triple Chip Grind (MTCG) Teeth
Commonly used in miter saws, its design provides clean and burr-free cuts in non-ferrous metal materials. It also ensures chip-free cutting of wood and wood products, minimizing the production of debris.
Commonly used for slotting and scoring laminated surfaces and plastic panels. It is also known as a scoring saw blade or a scribing saw blade.
Hollow Ground Saw Blades
Hollow face grind saw blades are used for cutting melamine board and other challenging-to-machine materials. They are typically used on vertical panel saws for efficient cutting.
Optimal Recommended Wood Cutting Circular Saw Blades
As mentioned, carbide refers to a hard compound material, denoted by the addition of a metal to it. In other words, another metal is combined with the carbide compound. Several materials can be incorporated into the carbide compound, including tungsten.
Tungsten, a hard metal with the highest melting point among all metals (over 3400 °C), boasts lower vapor pressure and higher tensile strength at temperatures above 1650°C. Tungsten carbide blades, due to their composition, have a higher RPM capacity compared to other blade types. These blades are particularly favored for cutting non-ferrous metals and plastic since they require less frequent sharpening than other blade varieties.
Carbide blades offer numerous advantages, including:
- Resistance to friction and minimal susceptibility to scratching.
- High wear resistance and unalterability.
- Ability to withstand temperature differences (melting point of 3400 °C)
- Non-corrosive properties.
- Long service life.
Tungsten carbide blades are suitable for clean and precise cuts on various materials, including softwood, hardwood, coated particleboard, non-ferrous metals, plastic, Plexiglas sheets, plywood, veneer, and MDF. They can also be effectively used for cutting aluminum, copper, and PVC.
