Can A Wood Bandsaw Be Used For Metal? (SOLVED)

To save money, some people consider converting their old wood bandsaw into a metal bandsaw. This article addresses the question: Can a wood bandsaw be used for metal?

Converting a wood bandsaw for metal cutting can be an appealing way to save money. However, there are crucial differences between wood and metal bandsaws that need to be understood. This article will discuss whether you can use a wood bandsaw for metal and the necessary modifications required.

Key Differences Between Wood and Metal Bandsaws

Feature	Wood Bandsaw	Metal Bandsaw
Blade Speed	3000-4000 FPM (Feet Per Minute)	150-300 FPM
Blade Thickness	1/8” to 2” width	Typically thicker for metal cutting
Blade Material	Wood-cutting blades (e.g., bi-metal)	Metal-cutting blades with carbide teeth
Price Range	Generally higher	Usually more affordable
Intended Use	Designed for wood	Specifically for metal and harder materials

Can a Wood Bandsaw Cut Metal?

1. Change the Blade

To effectively cut metal, the first step is to change the blade. Standard wood bandsaw blades are not designed for the increased toughness of metal. Here are some essential considerations:

Recommended Blades: Use high-quality blades such as Timber Wolf or Dewalt, which are known for durability and performance in metal cutting.
Blade Specifications:
- Teeth Count: Aim for 20-24 teeth per inch (TPI) to ensure a smoother cut.
- Blade Thickness: The thickness should ideally be around 0.032” or more, depending on your bandsaw’s capabilities.
- Wheel Diameter: The bandsaw’s wheels should typically range from 11 to 24 inches for optimal performance.

2. Adjust Blade Speed

The speed at which a bandsaw operates is crucial when cutting metal:

Wood Bandsaw Speed: Usually operates at 3000-4000 FPM.
Recommended Speed for Metal: To cut metal smoothly, you need to reduce the speed to between 150-300 FPM. This adjustment prevents overheating and prolongs blade life.

Why Speed Matters

Cutting metal at high speeds creates excessive friction, which can lead to:

Blade Damage: Higher speeds can cause blades to overheat and warp, resulting in breakage.
Material Deformation: The metal being cut may bend or twist under excessive force.

Safety Precautions

Safety should always be a priority when operating any saw, especially when transitioning from wood to metal:

Warning Signals: Implement warning signals in your workspace to alert nearby workers of potential hazards.
Use Blade Guards: Always use blade guards to prevent accidents from accidental contact with the blade.
Hydraulic Safety: Ensure that all hydraulic systems are turned off when not in use to prevent unexpected operation.

Can a Bandsaw Cut Other Materials?

Cutting Meat: Yes, with the right blade and speed adjustments, a bandsaw can effectively cut meat. Use a thin blade and set the speed to around 2000-3000 FPM.
Cutting Aluminum: A wood bandsaw can cut aluminum if equipped with the right blade. Opt for a blade with a higher tooth count (20-24 TPI) and adjust the speed to 5000 RPM for optimal performance.

Wrap Up

In conclusion, while it is possible to use a wood bandsaw for metal cutting, it requires specific modifications and careful attention to safety. The following key points summarize what you’ve learned:

Blade Change: Use a suitable metal-cutting blade.
Speed Adjustment: Reduce speed to prevent overheating.
Safety Measures: Follow strict safety protocols to avoid accidents.

While it can be tempting to adapt an existing wood bandsaw for metal work, investing in a dedicated metal bandsaw like the PORTER-CABLE or Milwaukee Metal Cutting Saw is advisable for long-term performance and safety.
