185mm Carbide Tipped Circular Saw Blade, 24 Teeth, 16mm Bore

The blade is the part of a circular saw that does the work, and a tired blade makes a good saw feel broken. Burning, a cut that wanders, smoke, a motor that labours and a finish that needs planing afterwards are all symptoms of a blunt or wrong blade rather than a worn out machine. A 185mm blade is the common size for handheld circular saws.

Twenty four teeth is the general purpose count. Fewer, larger teeth take a bigger bite, clear the sawdust better and cut faster along the grain, which is what you want for ripping boards, cutting rafters and sizing structural timber on site. A high tooth count blade gives a finer finish but cuts slowly and clogs in deep timber. Carbide tips are the reason the blade lasts, because carbide holds an edge far longer than plain steel and survives the occasional nail or grit in reclaimed timber, though not without damage. The blade is 185 by 1.8 by 16mm and rated to 7 000 revolutions a minute.
