Best 14-Inch Diamond Concrete Saw Blade: RPM & Price Compared
A 14-inch segmented diamond blade cuts concrete, brick, and masonry faster than a continuous-rim blade, but never exceed the RPM stamped on its core — 5,400 RPM is the safe ceiling for most 14-inch blades. Running a blade too fast or without a full guard risks a burst wheel and serious injury under OSHA 29 CFR 1910.215. This guide compares the Makita B-69646, RHAPSODY, and ORIXTREME by RPM, arbor size, and price.
| Blade | Max RPM | Arbor | Price | Best For |
|---|---|---|---|---|
| Makita B-69646 (3-pack) | 5,400 RPM | 1″/20mm | $259.97 | Contractors needing 3 spare blades on hand |
| RHAPSODY Xtreme Cut | 4,365 RPM | 1″-20mm | $39.99 | Budget wet/dry cutting, reinforced concrete |
| ORIXTREME Premium Segmented | 4,365 RPM | 1″-20mm | $46.99 | Brick and block, EN 13236-certified segments |
