Choosing the right sawmill blade depends on a few factors, such as the type of wood you’ll be cutting, the type of sawmill you’re using, and your specific needs in terms of cut quality and speed. Here’s a guide to help you make an informed decision:
1. Blade Material
- Carbon Steel Blades: Affordable and easy to sharpen, but wear down faster than other materials.
- Bimetal Blades: A combination of high-carbon steel and high-speed steel, offering a longer lifespan and the ability to handle tougher cuts.
- Carbide-Tipped Blades: Best for cutting dense or abrasive wood. These are durable and stay sharp longer but are more expensive.
2. Blade Type
- Band Saw Blades: Common for most portable and industrial sawmills. They offer flexibility, durability, and are available in various tooth configurations.
- Circular Saw Blades: Used in stationary sawmills, they provide fast cutting speeds and work well for straight cuts.
- Resaw Blades: Designed specifically for cutting thick wood into thinner boards, ideal for maximizing yield from logs.
3. Tooth Configuration
- Raker Set: Each tooth alternates in direction (left, right, straight), making this ideal for general cutting.
- Skip Tooth: Teeth have a wider spacing, making them suitable for cutting softer woods and reducing heat buildup.
- Hook Tooth: Teeth are angled forward for faster cutting in harder woods.
- Flat or Straight Tooth: Best for smooth, clean cuts in softwood.
4. Blade Thickness and Width
- Thicker Blades: Offer more durability and are less prone to deflection but may require more power to cut.
- Thinner Blades: Easier to maneuver and are good for fine, precise cuts but are more prone to wear and damage.
- Wider Blades: Provide more stability and are better for cutting thicker logs, but may cause more friction and heat.
- Narrower Blades: Offer better flexibility for curved or intricate cuts.
5. Blade Tension and Speed
- Consider the sawmill’s ability to tension the blade, as higher tension can provide a straighter, more accurate cut.
- Faster cutting blades often have a more aggressive tooth angle, but you might sacrifice the smoothness of the cut.
6. Wood Type
- Softwoods: Require less aggressive blades, often with a wider tooth set.
- Hardwoods: Harder woods may require carbide-tipped or high-speed steel blades to handle the density and minimize wear.
7. Sawmill Specifications
- Ensure that the blade is compatible with your sawmill’s size and horsepower. A high-powered sawmill may be able to handle larger, more aggressive blades, while a smaller sawmill might benefit from a thinner, more flexible blade.
8. Maintenance and Cost
- Some blades require more frequent maintenance, while others can be re-sharpened and used multiple times. Consider the cost of replacing and maintaining blades over time.

To sum up:
- Carbon steel for affordability and ease of sharpening.
- Bimetal or carbide-tipped for longevity and durability.
- Tooth configuration depends on your wood type (e.g., raker set for general use, skip tooth for softwoods, and hook tooth for hardwoods).
- Consider blade thickness and width for stability versus maneuverability.
By matching the blade characteristics with the type of wood and work you’re doing, you can improve both the efficiency and quality of your cuts.
