Circular Saw Arbors & Blades vs. Welding Wire & Electrode Sizes
Comparing 2 standards across 15 specifications. 15 key differences identified.
Comparing:
Circular Saw Arbors & Blades
Welding Wire & Electrode Sizes
Circular saw blade arbors (center mounting bore holes) are standardized into 5/8-inch (15.88 mm with diamond knockout for worm-drive saws), 1-inch (25.4 mm for table/miter saws), 20 mm, and 30 mm (European standard), paired with Alternate Top Bevel (ATB) or Triple Chip Grind (TCG) tooth geometries.
Welding filler metals are standardized under American Welding Society (AWS) and ISO specifications into MIG solid wires (.023", .030", .035", .045" / 0.6–1.2 mm), Stick SMAW electrodes (AWS E6010, E6013, E7018 from 3/32" to 5/32"), and TIG tungsten color-coded alloy classifications.
