Bosch Diamond Blade DB1265S 12 Inch Segmented Rim (1 Inch 20mm Arbor Wet Dry Asphalt Green Concrete Soft Masonry Slicing Cutoff Saw)

Bosch DB1265S 12-Inch Segmented Rim Diamond Blade for Asphalt and Green Concrete

The Bosch DB1265S 12-Inch Segmented Rim Diamond Blade is an industrial cutoff saw accessory engineered for high-speed deep slotting in abrasive substrates including asphalt pavement, freshly poured green concrete, and soft cinder block. Formulated with hard-bond synthetic diamond segments laser-welded to a 0.110-inch tensioned alloy steel core, this 1-inch and 20mm arbor wheel delivers up to 4 inches of cut depth per pass on portable gas cut-off saws and walk-behind saws. Designed with wide segmented gullets that clear abrasive slurry, this dual wet-or-dry cutting blade prevents premature core undercut while maintaining straight cut tracking across road repair sites.

Best Used For:

• Asphalt Pavement & Street Patching: Cutting clean expansion joint borders and trench perimeters in asphalt roadways prior to excavation.
• Green Concrete Expansion Joint Slotting: Slicing stress-relief joints in freshly poured green concrete slabs before full thermal curing.
• Abrasive Masonry & Soft Block Shearing: Sizing cinder blocks, lightweight aggregate brick, and soft stone masonry without blade glazing.

Key Performance & Safety Features

• Hard-Bond Matrix Segment Formulation: Engineered to withstand severe slurry abrasion when cutting highly abrasive green concrete and asphalt.
• Laser-Welded Segmented Rim: Deep gullet spacing ejects thick aggregate slurry rapidly while directing air to cool the internal steel plate.
• Tensioned 0.110-Inch Alloy Steel Core: Heavy-gauge steel plate resists lateral deflection, wobble, and thermal warping under heavy cutting force.
• 1-Inch and 20mm Dual Arbor Compatibility: Fits standard gas power saws, masonry table saws, and walk-behind concrete joint saws.
• 4-Inch Maximum Cutting Depth: Wide 12-inch blade diameter allows full-depth single-pass cutting on standard 4-inch asphalt overlays and slab joints.
• Wet and Dry Application Capability: Operates efficiently dry for rapid field trenching or wet with water spray to suppress silica dust and extend rim life.

Pro-Tip: Use continuous water flow when cutting abrasive green concrete or asphalt; flooding the kerf flushes away loose sand aggregate that can otherwise wear down the steel blade core behind the diamond segments.
