DeWalt DW8021 14" x 1/8" x 20mm High-Speed Metal Cutting Abrasive Blade
The DEWALT DW8021 14-inch abrasive metal cutting blade slices, crops, and sections heavy-gauge carbon steel, concrete reinforcing bar, structural steel tubing, and schedule 40 pipe across industrial metal fabrication jobs and commercial jobsites. Formulated with high-concentration A24R aluminum oxide grain bonded to two full sheets of heavy-duty woven fiberglass mesh, this 1/8-inch abrasive cut-off wheel delivers high material removal rates while resisting wheel flutter at speeds up to 5,500 RPM. Designed with a 20 mm (0.787-inch) precision arbor hole for direct mounting on high-speed portable gas cut-off saws, it equips structural ironworkers, mechanical contractors, and pipefitters with straight, burr-minimized cuts and long-lasting wheel stamina under continuous abrasive loads.
Best Used For:
-
Structural Steel and Sectioning: Slicing through heavy carbon steel angle iron, channel stock, unistrut, and hollow structural sections (HSS).
-
Rebar and Heavy Solid Rod Cropping: Shearing high-tensile ASTM Grade 60 deformed rebar bundles, anchor bolts, and cold-rolled steel round stock cleanly before placement.
-
Industrial Pipe and Tubing Fabrication: Cutting thick-wall schedule 40/80 carbon steel pipe, galvanized conduit, and stainless steel tubes to specified lengths.
Key Performance & Safety Features
-
Industrial A24R Aluminum Oxide Formulation: High-density crystalline grain matrix delivers rapid abrasive cutting speed and extended wheel service life.
-
Dual High-Tensile Fiberglass Reinforcement: Two full sheets of reinforced woven fiberglass mesh provide structural rigidity and prevent wheel shatter under high centrifugal stress.
-
5,500 RPM Maximum Speed Rating: Engineered to withstand peak rotational surface speeds on handheld high-power portable gas cut-off saws.
-
Optimized 1/8-Inch Kerf Profile: Balances rapid cutting penetration with lateral wheel stiffness to eliminate blade deflection and wandering in thick stock.
-
Direct-Fit 20 mm (0.787") Precision Arbor: Machined center hole ensures centered, concentric mounting to reduce tool vibration and spindle bearing wear.
-
Broad Metallurgy Versatility: Engineered for efficient cutting across mild steel, high-tensile carbon steel, structural alloys, and stainless steel.

Pro-Tip: Pro-Tip: Allow the cut-off saw engine to achieve full operating RPM before engaging the steel workpiece, and apply steady, moderate pressure rather than forcing the wheel. Letting the high-density A24R aluminum oxide grain do the cutting prevents wheel glazing, reduces heat buildup, and delivers faster cut cycles with minimal edge burring.
