Frequently Asked Questions
Q: How often should I replace my OSB saw blade?
A: Expect 50–150 cuts before dulling depending on tooth count and material density. Replace when cuts become slower or splintered.
Q: Can I use a regular plywood blade for OSB?
A: Not recommended. OSB’s density requires more aggressive teeth (120T+) and harder steel to resist wear.
Q: Do carbide-tipped blades last longer?
A: Yes. Carbide holds up to 3x longer than carbon steel, especially on abrasive materials like OSB.
Q: What’s the difference between 120T and 144T blades?
A: Higher tooth counts (144T) create smoother cuts but require more passes. 120T is versatile for most OSB projects.
