Diablo DBD040040101F 4" x 0.040" Type 1 Thin Kerf Metal Cut-Off Disc
The Diablo DBD040040101F 4-inch Type 1 flat metal cut-off disc delivers razor-sharp, burr-free straight cuts across structural steel, stainless steel tubing, cast iron pipe, and sheet metal panels. Engineered with a premium aluminum oxide abrasive grain blend and an ultra-thin 0.040-inch kerf profile that reduces power draw and friction on angle grinders, this 15,250 maximum RPM wheel speeds up cutting cycles while extending disc service life. Outfitted with high-tensile multi-layer fiberglass mesh reinforcement and a standard 5/8-inch arbor interface, it equips certified welders, mechanical plumbers, and metal fabrication contractors with clean, spark-controlled metal slicing performance.
Best Used For:
- Thin-Wall Conduit and Tubing Slicing: Slicing stainless steel lines, EMT electrical conduit, and copper pipe with minimal heat discoloration and virtually no burr formation.
- Structural Steel and Rebar Parting: Cutting through mild steel angle iron, threaded rod, solid round bar, and structural framing channel on tight jobsites.
- Auto Body and Sheet Metal Fabrication: Trimming heavy automotive sheet metal, exhaust components, and floor panels cleanly in confined clearances.
Key Performance & Safety Features
- Ultra-Thin 0.040-Inch Kerf Geometry: Slices through dense metals with reduced cutting resistance, minimizing motor bog-down and battery drainage on cordless tools.
- Premium Aluminum Oxide Abrasive Blend: Delivers rapid material penetration and exceptional grain durability under high-friction industrial cutting.
- Multi-Layer Fiberglass Reinforcement: High-tensile woven fiberglass mesh provides maximum burst resistance and operator protection under extreme lateral side loads.
- Type 1 Flat Wheel Architecture: Allows deep, straight-line plunge cuts and flush sectional trimming in narrow workspaces.
- High-Speed 15,250 Maximum RPM Rating: Dynamically balanced body minimizes tool chatter and vibration to improve cutting accuracy and reduce user fatigue.
