Choosing the right bandsaw blade doesn’t have to be complicated. With so many options for materials, TPI, blade widths, and lengths, it’s easy to feel overwhelmed. But by breaking the process into manageable steps, you can confidently select the blade that matches your project needs. This guide condenses everything we’ve shown so far in our five band saw blogs and includes practical tools—charts and diagrams—to help you make the best choice.

Step 1: Match the Blade to Your Material
The material you’re cutting is the most important factor in blade selection. Different materials require different blade types:

• Wood and Plastics: Use carbon steel blades for their affordability and flexibility.
• Metals and Mixed Materials: Choose bi-metal blades for their durability and ability to handle tougher tasks.

Material	Recommended Blade Type
Softwoods, hardwoods, plastics	Carbon Steel Blade
Metals, dense hardwoods, composites	Bi-Metal Blade

Step 2: Choose TPI Based on Material Thickness

TPI (teeth per inch) affects cut speed and finish. Lower TPI blades are faster but rougher, ideal for thick materials. Higher TPI blades are slower but smoother, perfect for thin or delicate materia

TPI Range	Best For	Examples
3 - 6 TPI	Thick materials, rough cuts	Logs, beams, thick hardwoods
8 - 14 TPI	General-purpose, balanced cuts	Plywood, plastics, medium woods
18 - 24 TPI	Thin materials, smooth cuts	Veneers, plastics, soft metals

Blade Width	Best Uses	Material Recommendations
1/8"–1/4"	Tight curves, intricate patterns	Softwoods, thin plywood, plastics
3/8"–1/2"	General-purpose, moderate curves	Medium-density woods, plastics
3/4"+	Straight cuts, resawing, heavy-duty	Hardwoods, dense composites

Step 4: Ensure Length and Compatibility

Blade length must match your band saw’s specifications. Check your user manual or measure your blade path. Longer blades are for industrial machines; shorter ones fit compact models.

Blade Length	Best Uses	Compatible Machines
56-7/8" to 72"	Compact, hobbyist applications	Small band saws (e.g., benchtop models)
80" to 105"	Standard workshop projects	Medium-sized band saws
Over 105"	Industrial and heavy-duty applications	Large, professional-grade band saws

Final Thoughts

Selecting the right band saw blade is about balancing your project’s needs with your machine’s capabilities. By considering material, TPI, width, and length, you can find a blade that delivers the best results for your work.

Flowchart: Your Blade Selection Made Easy

1. What Material Are You Cutting?

• Wood or Plastic → Carbon Steel Blade
• Metal or Mixed Materials → Bi-Metal Blade

2. What Type of Cut?

• Straight → Wide Blade (3/4"+)
• Curves → Narrow Blade (1/8"–1/4")

3. Material Thickness?

• Thick → Low TPI (3–6)
• Thin → High TPI (18–24)

4. Is the Blade Compatible with Your Machine?

• Check length and width specifications in your user manual.
