OA-BRES 3-Pack 4-1/2-Inch 60-Grit Diamond Blade, 3/8-Inch Arbor – Tile, Stone & Masonry

Smart value, serious cutting power

Meet OA-BRES 3-pack of 4-1/2-inch diamond blades designed to deliver reliable performance without the premium price. Each blade uses a 3/8-inch arbor and a 60-grit diamond edge, built for steady, controlled cuts through ceramic tile, stone tile, backer board, cement, and other masonry substrates.

With three blades in every pack, you’ll have extended cutting life for longer projects and fewer mid-task changes. These blades are designed to fit several popular compact saws, including Rockwell RK3441K and RK3440K 4-1/2-inch models, the WORX WX429L, and the PORTER-CABLE Pce381, giving you flexibility across tools you already own.

Designed for cooler, cleaner cuts

The blade’s segmented design improves airflow, helping to dissipate heat and reduce dust buildup. The result is smoother, faster cuts and less blade wear during longer sessions, so you can stay productive without sacrificing edge quality.

What these blades excel at

• Materials: ceramic tile, stone tile, backer board, cement, concrete, roof tiles, brick, block, marble, granite, paving, masonry
• Performance: engineered for reliable cutting at up to 13,000 RPM on dense substrates
• Durability: heat-treated manganese steel with #60 diamond grit for longer blade life
• Compatibility: fits Rockwell RK3441K, RK3440K 4-1/2 inch mini saws, WORX WX429L, and PORTER-CABLE Pce381

Whether you’re tackling a bathroom remodel, installing new tile floors, or adding a durable countertop edge, OA-BRES blades offer a practical blend of value and capability. Results can vary by technique and material, but many users report precise edges, cleaner cuts, and reduced rework on common substrates.

User guidance

Let the blade do the work with a steady feed, maintain cool operation, and inspect wear regularly. Replacing blades promptly when wear is evident helps sustain cutting performance across projects.
