Dewalt DT4097-QZ Circular Saw Blades Series 40 D235/BS30/2.2/3/56/TCG/-5DEG

Key specs: diameter 235 mm, bore 30 mm, thickness 2.2 mm, 56 teeth, triple-chip grind (TCG). It features a non-stick coating to lower friction and resin buildup, enabling smoother cuts and longer blade life.

The blade is suitable for use with a range of circular saws, including sidewinders and worm-drive models, thanks to its 30 mm bore and 235 mm diameter. It’s designed for up to 7,200 rpm for high-speed cutting.

Unplug the saw, remove the existing blade, and align the teeth direction with the saw’s stroke. Slide the blade onto the arbor, secure with the flange and nut, and ensure the blade sits flat and spins true before powering the saw back on.

Support the workpiece firmly, feed steadily without forcing the blade, and use a suitable fence or guide. The anti-kickback teeth design and thin kerf help reduce kickback and improve control for cleaner cuts.

Wear appropriate PPE (eye, ear, and hand protection). Keep guards in place, secure the workpiece, and avoid forcing the blade. The anti-kickback tooth design contributes to safer cutting by reducing kickback risk.

The 56-tooth count with TCG enhances cutting efficiency and chip evacuation on wood, delivering a good balance between speed and finish quality. The design is particularly effective for crosscuts and ripping through varied wood densities.

Keep the blade clean and free of resin buildup, use a clean and sharp cut, and avoid overheating by cutting at appropriate speeds. Regularly inspect teeth for dullness or chipping and replace when performance declines.

Ideal for framing lumber, plywood sheets, and general woodworking where clean, precise cuts are desired. The thin kerf and anti-stick coating help with smooth rips and panels where finish quality matters.

Yes, the thin kerf design and 56-teeth configuration support smoother cuts on plywood and laminated boards, reducing tear-out and producing cleaner edges.
