The DeWalt DW3330 is a 7-1/4" precision-sharpened steel circular saw blade for ferrous metal cutting in mild steel sheet, angle iron, light tube, threaded rod, and thin-wall conduit. Fully hardened steel body resists warping under load, the thicker plate gives a stable cut with less wobble, and the 5/8" round arbor fits all standard 7-1/4" worm-drive and sidewinder circular saws.

• Size: 7-1/4" diameter, 5/8" round arbor
• Application: Steel/Iron Cut-Off
• Precision-sharpened teeth for fast, smooth cuts
• Thicker plate body for stable, true cuts under load
• Fully hardened steel body resists warping
• Fits all standard 7-1/4" circular saws (worm-drive and sidewinder)

Application: Steel and iron cut-off blade for mild steel sheet, angle iron, light tube, threaded rod, EMT and rigid conduit, and other ferrous metal stock. Use the blade in a circular saw or chop saw rated for metal cutting, secure the work in a vise or clamp, and let the blade reach full speed before contacting the material. Wear safety glasses and a face shield - metal cutting throws hot sparks and chips. Not for non-ferrous metals - use the DW3329 instead.

Blade Family Selection: Match the blade to the material. Combination (DW3325) for general wood, plywood (DW3326) for finish wood and panels, non-ferrous (DW3329) for aluminum/brass/copper, steel cut-off (DW3330) for ferrous metals. Using a wood blade in metal or a metal blade in wood destroys the teeth and can throw the blade.

Cutting Tip: Let the blade reach full RPM before touching the material. Keep the saw shoe flat against the work, feed at a steady rate, and don't force the cut - if the saw bogs down, back off and let the blade clear. Listen to the blade: a clean cut sounds smooth, a forced cut hums and burns. Inspect the teeth before each use; cracked or chipped teeth can shed at speed.
