Complete Buying Guide for Best Saw Blades for Hardie Siding
Essential Factors We Consider
When choosing a Hardie siding blade, focus on three key factors: PCD tooth count, kerf thickness, and arbor compatibility. More PCD teeth mean faster cuts but may increase cost. A thinner kerf reduces material waste, while arbor size ensures proper fit for your saw. Always match the blade’s RPM rating to your equipment specs.
Budget Planning
Expect to spend $20-$60 depending on features. Budget options (like Wen’s BL0704) deliver PCD performance without premium prices. Mid-range blades (Diablo’s D0704DH) offer better durability, while high-end models provide specialized features like noise reduction. Consider how frequently you’ll use the blade—daily projects justify investing in higher-end options.
Final Thoughts
No single blade fits every scenario. The HardieBlade 4T excels for versatility, Diablo D0704DH for pros, Wen BL0704 for budgets, Twin-Town PCD71406 for dense materials, and TOMAX PCDM71404 for value. Test if possible blade feel and cut quality matter as much as specs!
Frequently Asked Questions
Q: How do I know if my blade suits my Hardie?
A: Match the arbor size (typically 5/8″ or 1/2″) to your saw. Check RPM ratings most Hardie blades run at 5,000-8,000 RPM. Avoid exceeding manufacturer limits to prevent premature dulling.
Q: Will a PCD blade last years?
A: Yes! Properly stored, PCD blades maintain sharpness for 500+ cuts or several seasons. Clean debris between uses and store vertically to preserve edges.
Q: Can I use these for non-Hardie materials?
A: Absolutely! These blades excel on fiber cement, laminate, MDF, and Corian due to their diamond-tipped teeth resisting abrasion.
