Diablo Diamond Grit Oscillating Blade DOU16DGX Universal Fit Grout Removal Multi Tool Segment (1/16 Inch Joint Thickness Tile Mortar Backerboard)

Diablo DOU16DGX Universal Fit Diamond Grit Oscillating Grout Removal Blade

The Diablo DOU16DGX is a 2-3/4-inch diamond grit oscillating multi-tool blade engineered for fast grout removal, mortar clearing, and tile joint repair down to 1/16-inch thicknesses. Constructed with a permanently bonded industrial diamond grit edge, this segmented blade resists abrasive heat and wear when cutting through cured epoxy grout, cement backerboard, and thinset mortar. Its curved segment geometry allows precision plunge cuts into tight corners and flush edges without damaging adjacent ceramic, porcelain, or stone tile faces, while the universal adapter-free shank mounts directly onto major corded and cordless oscillating multi-tools.

Best Used For:

• Precision Tile Regrouting & Repair: Clearing failed or stained grout lines down to 1/16-inch joints without chipping surrounding ceramic or porcelain tile.
• Cement Backerboard & Plaster Trimming: Making plunge cuts and flush wall edge adjustments in dense cementitious backerboard panels during bathroom remodeling.
• Epoxy Grout & Mortar Scrape Out: Stripping hardened epoxy grouts, stubborn adhesive bed remnants, and masonry mortar from floor seams.

Key Performance & Safety Features

• Industrial Diamond Grit Edge: Permanently bonded diamond matrix delivers superior wear resistance and rapid material removal in abrasive masonry.
• Universal Adapter-Free Interface: Direct-mount shank design fits major oscillating tool brands without requiring loose spacers or separate adapters.
• Curved Segment Layout Geometry: Curved cutting profile enables controlled plunge cuts into restrictive corners and recessed tile intersections.
• 1/16-Inch Narrow Joint Capacity: Thin blade edge tracks cleanly down standard 1/16-inch tile seams to prevent binding and tile face damage.
• Cordless Runtime Optimization: Low-friction edge design minimizes motor resistance to conserve battery power on cordless multi-tools.
• Multi-Brand Machine Compatibility: Connects directly to tool platforms from DeWalt, Milwaukee, Makita, Bosch, Ridgid, Craftsman, and Porter-Cable.

Technical Specifications

Pro-Tip: Maintain a low oscillation speed setting when clearing dense epoxy grouts to keep friction temperatures low; letting the diamond grit wear through the material prevents heat buildup that can discolor surrounding tile glaze.
