What it is
The Extreme DeWalt DT4321-QZ blade is a circular saw accessory dedicated to cutting wood, with a diameter of 250 mm and a 30 mm bore. The 30-tooth configuration, with clockwise direction of rotation, is designed to deliver efficient, even cuts in wood. Its specific wood application clearly defines its field of use.
A circular saw blade is a toothed disc, usually carbide-tipped, for circular saws, mitre saws and plunge saws; it cuts wood, panels, metals and plastics.
What it is for
Used for cutting solid wood, panels and battens, on the bench or on site.
How to use it
Choose a blade with a diameter, bore and kerf compatible with the machine and teeth suited to the material: fewer teeth for fast cuts, more for fine cuts. With the machine unplugged, fit it with the rotation arrow matching that of the saw and tighten the flange. Cut with the guard working, letting the blade reach full speed before entering the workpiece, and wear safety glasses and hearing protection.
