AI picks by need

Milwaukee M18 Double Cut Shear (line)
A double-cut design keeps both sides of duct and panel stock flat, with full-size battery power.
Not for: Users who need the lightest tool for overhead work.
What the AI looks for in Power Shears
- Single vs double cut
- Choose double cut when both sides of the sheet must stay flat, and single cut for fastest straight trimming. A single-cut shear curls one edge, and a double-cut shear removes a strip instead.
- Rated gauge capacity
- Match the rating to your thickest mild steel, and expect a lower rating for stainless. Undersized shears stall and leave torn edges.
- Minimum cutting radius
- Check the stated radius if you cut curves or round duct openings. Shears cannot turn as tightly as nibblers. Past their radius they bind and tear.
- Blade replacement
- Confirm that replacement blades are sold for the exact model and can be changed without special tools. Shear blades dull with use, especially on galvanized and stainless steel.
- Head rotation
- Prefer a swivel head for cutting inside boxes, along walls or overhead. It keeps your wrist neutral and the cut steerable.
Brands that matter
- Makita: Long-standing corded shear line with good parts support.
- Milwaukee: M12 and M18 cordless shears common in HVAC.
- DeWalt: 20V MAX swivel-head double-cut shear.
- Malco: TurboShear drill attachments for light, occasional use.
- Metabo: Corded shears for heavier gauges.
What to avoid
- Forcing a shear through corrugated or ribbed panels
- Running galvanized or stainless steel at or past the rated gauge
