DEWALT Portable Band Saw Blade, 32-7/8-Inch, .020-Inch, 18 TPI, 3-Pack (DW3983C)
The DEWALT blade features Matrix II high-speed steel edges designed for enhanced heat and wear resistance, with 8% cobalt content for added durability and a Rockwell hardness of Rc 65-67. This combination makes it well-suited for cutting through soft ferrous metals and other common metals in a factory or workshop setting. Best for operators who want dependable, long-lived blades for portable band saw tasks and who regularly tackle tough cuts that generate heat.
Best for: Metal fabrication shops and DIYers needing reliable performance with minimal blade changes. Consider this blade if you frequently cut softer steels or aluminum where heat buildup is a concern. Limitation: High cobalt content can make the blade slightly more brittle if used aggressively on extremely tough alloys.

Buying Guide: Choosing The Right 18 TPI Bandsaw Blade
Key factors to weigh when selecting an 18 TPI blade include blade length, width, and compatibility with your portable band saw. Material quality, tooth design, and steel type directly influence cutting performance and durability. Consider the following questions:
- What material will I cut most often (soft ferrous metals, aluminum, or mixed metals) and how hot will the blade get in my typical workflow?
- Do I need a longer blade for extended cuts, or is a compact blade better for tight spaces?
- Which band saw brands and models am I using, and is blade length officially compatible?
- Is a bi-metal blade preferred for its wear resistance, or would a standard high-speed steel edge suffice?
- What is my acceptable balance between blade life and initial cost?
Practical Buying Tips
- For frequent long cuts on soft ferrous metals, prioritize longer blades with robust wear resistance (bi-metal options like M42 steel).
- If you switch between saw brands, choose blades with broader compatibility and standard blade dimensions like 44-7/8″ or 44-7/8″ long blades.
- Check blade thickness; thicker blades typically offer greater durability but may be harder to start in tight corners.
- A hook teeth profile can improve aggressive cutting and material removal for certain metals.
- Verify the exact blade length, width, and tooth configuration for your specific saw model before purchasing.
FAQ
- What is 18 TPI and when should I use it?
– 18 teeth per inch (TPI) is a balance between fast material removal and fine finish, suitable for soft ferrous metals and similar materials in portable band saws. - Are bi-metal blades worth the extra cost?
– Bi-metal blades combine high-speed steel teeth with a flexible backing, offering longer life under heat and stress, especially in metal cutting tasks. - Can I use a 44-7/8″ blade in a compact portable saw?
– It depends on your model’s blade length requirement; confirm compatibility with the manufacturer’s specifications. - Should I choose a blade with an 0.020″ thickness or a thicker variant?
– 0.020″ is common for balanced rigidity and flexibility in portable saws; thicker blades resist flexing but may require more precise setup. - Which blade is best for a mixed metal shop?
– A versatile 44-7/8″ blade with 18 TPI from a reputable brand often provides consistent results across several models and tasks. - What maintenance helps extend blade life?
– Keep blades clean, avoid dry running, and ensure the blade is properly tensioned and aligned to minimize premature wear and heat buildup.
