Complete Buying Guide for Reciprocating Saw Blades For Aluminum
Essential Factors We Consider
When searching for the best blades, always look at the TPI (teeth per inch). Higher TPI is better for thinner materials, while lower TPI works well for thicker sections. Additionally, the material of the blade—either bi-metal or carbide-tipped—will determine how long the blade lasts against the heat generated during metal cutting.
Budget Planning
If you have occasional projects, mid-range bi-metal blades are perfect. However, if you are a professional working with aluminum daily, investing in carbide-tipped blades is highly recommended because they pay for themselves by reducing the need for constant replacements.
Final Thoughts
Your choice of blade is the most important factor in how easy your work feels. Don’t be afraid to try a carbide blade if you are tired of your current blades dulling after just a few cuts. Quality gear makes every project run smoother.
Frequently Asked Questions
Q: Can I use wood blades for aluminum?
A: No, you should not. Wood blades have larger, hook-like teeth that can catch or shatter when hitting aluminum, which is extremely dangerous. Always use metal-cutting or bi-metal blades.
Q: How can I make my blade last longer when cutting aluminum?
A: Use a slow to moderate cutting speed and keep the blade lubricated with cutting oil or a light lubricant to prevent overheating and chip buildup.
Q: What does TPI stand for?
A: TPI stands for “Teeth Per Inch.” As mentioned earlier, more teeth per inch provide a smoother finish on thin aluminum, while fewer teeth per inch allow for faster, more aggressive cutting on thicker pieces.
