In woodworking, the quality of a cut is greatly influenced by the type of saw blade used, particularly its teeth. This guide focuses on two crucial aspects: achieving a smooth cut and selecting the right teeth type for that purpose.
Let’s dive into this article and decide which blade is best for you.

Understanding the Types of Cuts
Cross Cuts: Ideal for cutting across the wood grain. Recommended saws are crosscut saws with higher tooth counts for finer finishes.
Rip Cuts: Best for cutting along the wood grain. Rip saws with fewer, larger teeth are recommended for efficient, faster cuts.

Combination Cuts: Combination saws with a balanced tooth count and gullet size are ideal for versatility in both cross and rip cutting.
Fine Finish Cuts: Fine-toothed blades are recommended for detailed work requiring a polished finish.
Rough Cuts: For initial sizing or where the finish is not a priority, saws with fewer teeth and aggressive cuts are preferred.
Choosing The Best Tooth Design For Smooth Cuts
To achieve smooth cuts in woodworking, the design of the saw teeth is critical. Each type of tooth design contributes to the smoothness of the cut in different ways:
Alternate Top Bevel (ATB)
The ATB design features teeth that alternate between a right-hand and left-hand bevel. This configuration allows the blade to make cleaner, finer cuts with less effort.
The angled bevels effectively slice through the wood fibers, reducing tear-out and leaving a smoother surface.
High Alternate Top Bevel (Hi-ATB)
This is a variation of the standard ATB with a higher bevel angle on the teeth. The increased angle enhances the slicing action of the blade, making it even more effective at producing a polished finish.
Hi-ATB blades are especially useful for cutting materials that easily splinter, such as veneers and laminates, as they minimize chipping and leave a smoother edge.
Triple Chip Grind (TCG)
In TCG blades, the teeth alternate between chamfered and raker teeth. This unique combination allows efficient cutting while minimizing chipping, particularly in harder materials.
The chamfered teeth gently remove the bulk of the material, while the raker teeth clean up the cut, resulting in a smoother finish.
Combination Tooth
Combination saw blades merge Alternate Top Bevel (ATB) and Flat Top Grind (FTG) teeth, effectively balancing ripping and crosscutting.
The ATB teeth contribute to smoother finishes, while the FTG teeth provide aggressive cutting action. This combination makes these blades versatile and suitable for woodworking tasks requiring smooth cuts.
Flat Top Grind (FTG)
Primarily known for efficient ripping, high-quality FTG blades can achieve smooth cuts in certain conditions, like in softer woods or with controlled feed rates.
The flat-top teeth cut efficiently and, when sharp and used properly, can leave a surprisingly smooth finish for a rip blade.
Summing Up
| Tooth Design | Ideal For | Cut Quality |
| ATB (Alternate Top Bevel) | General Purpose | Cleaner, Finer Cuts |
| Hi-ATB (High Alternate Top Bevel) | Splinter-prone materials | Polished Finish |
| TCG (Triple Chip Grind) | Harder materials | Minimizes Chipping |
| Combination Tooth | Ripping & Crosscutting | Versatile, Smooth Cuts |
| FTG (Flat Top Grind) | Ripping in softer woods | Efficient, Smooth Cuts |
Choosing The Best Tooth Count and gullets For Smooth Cut
It’s not as simple as stating a definitive number for the ideal tooth count for smooth cuts, as everyone’s needs differ. Therefore, we aim to detail each tooth count range, enabling you to make an informed choice based on your specific requirements. While blades with 60-100 teeth generally yield smoother cuts, there’s more to consider in your selection process.
In addition to tooth count, the gullet size of a saw blade is a significant factor influencing the quality and smoothness of cuts:
Crosscut Blades (60-100 Teeth): These blades have finer teeth for a smooth, fine finish. The gullets (spaces between the teeth) on these blades are relatively smaller, allowing more teeth to fit on the blade. Smaller gullets limit the amount of wood removed with each tooth pass, reducing the cut’s aggressiveness but improving the finish’s smoothness and quality.
Rip Blades (10-30 Teeth): Designed for efficient, coarser cuts along the wood grain, rip blades have fewer and larger teeth. The gullets on these blades are significantly larger to accommodate the larger chips produced during ripping. This larger gullet size allows for faster chip removal, essential for the quicker, more aggressive cuts needed in ripping operations.
Combination Blades (40-50 Teeth): Balancing smoothness and efficiency, combination blades are designed for crosscutting and ripping. Their gullets are a compromise between the finer crosscut and the coarser rip blades. These gullets are sized to provide efficient chip removal (necessary for ripping) while maintaining a smoother finish (as required in crosscutting).

Our General Practices (Tips) For Getting Smooth Cuts
- Ensure precise measurements and markings for a correct starting point, minimizing post-cut corrections.
- Firmly clamp the wood to prevent movement, leading to cleaner and more accurate cuts.
- Choose blades with higher TPI for thin wood and appropriate tooth geometry for the material, reducing tear-out.
- Maintain a consistent, controlled motion to avoid rough cuts.
- Take your time and use sharp blades to prevent uneven cuts and splintering.
- Use proper body positioning and apply moderate, consistent pressure and slow feeding for smooth blade movement.
- Keep the blade aligned with marked lines to ensure straight, smooth cuts.
I believe by now, you have a good grasp of which tooth type and TPI (Teeth Per Inch) are best for your projects. However, if there’s still any uncertainty, we’re here and more than willing to assist you!
