Why Cheap Diamond Blades Cost More: Analyzing Cost-Per-Cut vs. Upfront Price
Direct Answer: Cheap economy diamond blades cost significantly more over time because they contain lower diamond concentration, inferior synthetic diamond grades, and short 7mm–10mm segment heights that wear out up to 4x faster than commercial-grade blades. When factoring in worker labor downtime ($50-$80/hr) for frequent blade swaps, slow cutting speed, and elevated saw engine wear, premium commercial blades with 12mm-15mm segments deliver a 30% to 50% lower total Cost-Per-Cut foot.
