The shapes of saw blade teeth determine the way, quality, and speed of cuts. This post explains 4 circular saw blade tooth shapes, including Flat Top Grind (FTG), Alternate Top Bevel (ATB), Triple Chip Grind (TCG), and Combination Tooth (Comb).
Each saw tooth grind presents distinct differences in cutting speed, cut precision, wear resistance, and material compatibility. Choosing the correct circular saw blade teeth improves cut accuracy, reduces tear-out, and extends blade life.
We explore the four saw blade tooth grinds from their features and applications. Hope you can select the right saw blade for your project after reading this article.
Flat Top Grind - FTG
Flat Top Grind (FTG) has a simple design and is a durable saw blade tooth grind. It features a square, flat tooth profile. The large gullets are efficient for chip removal. It has a low tooth count, suitable for fast cutting, but not for fine finishing.
Because all teeth share the same flat profile, the FTG circular saw blade teeth distribute cutting force evenly and allow fast feed rates. The wood is less likely to chip and splinter when it’s being cut along the grain. Therefore, the FTG teeth excel in ripping wood and making grooves.
Additionally, the FTG saw blade teeth are highly resistant to impact and wear. They are better suited for handling nails, knots, and dense wood.
- Strength: Durable, efficient, fast cutting speed.
- Weakness: Rough finishes.
- Best for: Ripping solid wood and creating grooves.
Alternate Top Bevel - ATB
Alternate Top Bevel (ATB) is a widely used type of saw blade teeth in woodworking. The blade teeth alternate between right- and left-leaning bevels. This tooth arrangement creates a shearing cutting action.
The ATB saw blade teeth feature a high tooth count, ensuring smooth cuts across the wood grain. The angled saw tip grinds slice wood fibers cleanly, reducing splintering and tear-out. They are commonly used for cutting wood, plywood, veneer, hardboard, fiberboard, and particle board.
- Strength: Smooth finish, minimal tear-outs.
- Weakness: Wear out fast and are difficult to sharpen.
- Best for: Crosscutting solid wood, fine finishing.
High Alternate Top Bevel - Hi-ATB
High Alternate Top Bevel (Hi-ATB) uses a steeper bevel than the standard ATB, alternating angles over 20º between teeth. The Hi-ATB tooth form minimizes tear-outs and produces extremely clean edges on delicate or brittle surfaces.
However, this saw tip style sacrifices durability for a superior surface finish. It is not recommended to use it for ripping or cutting abrasive materials.
- Strength: Clean edges with minimal splintering.
- Weakness: Dulls faster.
- Best for: Delicate cross cuts through plywood, melamine, and thin laminates.
Triple Chip Grind - TCG
Triple Chip Grind (TCG) teeth feature alternating trapezoidal chamfered teeth and flat-top teeth. The chamfered teeth cut first, and then the flat-top teeth clean the chips. This alternating tooth form is designed to reduce chipping and extend blade life.
TCG circular saw blade teeth excel at cutting dense and abrasive materials. They may also be used for cutting wood, but they can’t produce the smoothest cut.
- Strength: Reduced chipping, long-lasting, and heat-resistant.
- Weakness: Not ideal for fine woodworking finishes.
- Best for: Cutting non-ferrous metals, aluminum, plastics, laminates, and MDF.
Combination Tooth - Comb/ATBR
The combination tooth is the combination of ATB and FTG, also called comb or ATBR. It is a general-purpose saw-tooth configuration, suitable for both ripping and crosscutting. The ATB teeth create clean edges, while the flat-top raker removes chips and improves cutting stability.
The combo blade is ideal for small workshops, jobsite saws, and DIYers.
- Strength: Little tear-out and efficient chip removal.
- Weakness: Wears rapidly.
- Best for: Mixed ripping and crosscutting.
Best Circular Saw Blade for Woodworking
Understanding the shapes of saw blade teeth is essential for choosing the right circular saw blade. For clean and precise wood cutting, ATB saw blade tooth shapes are best suited for crosscutting and general woodworking applications.
A 10-inch, 60-tooth ATB circular saw blade is considered a standard configuration for table saws or miter saws. It offers a controlled feed rate, reduced tear-out, and consistent surface finish when cutting solid wood and plywood.
Based on these criteria, the FindBuyTool 10-inch 60-tooth circular saw blade features ATB tooth geometry suitable for woodworking. It provides smooth, accurate cuts with reduced tear-out and vibration, making it a practical upgrade for home workshops.
