DeWalt DW66C-1 Coil Siding Nailer Review
Verdict: the DeWalt DW66C-1 is a solid, durable coil siding nailer and the natural pick if you prefer the DeWalt name — it goes toe-to-toe with the Bostitch N66C on nail range and depth control, at a slightly higher price.

Build and feel
DeWalt built the DW66C-1 tough — a durable magnesium/aluminum body, comfortable grip, and reliable feed. At about 5 pounds it's easy to run along a wall, and it covers the full 1¼″–2½″ coil siding nail range, so it doubles for fencing and decking like any good coil siding gun.
Depth control
Tool-free depth adjustment lets you dial nails flush on wood or fiber cement, or leave vinyl slightly loose. As always with siding, set it on a scrap piece before you start the wall.
Pros
- Durable, well-built body
- Full 1¼″–2½″ nail range
- Tool-free depth control
- Handles siding, fencing, decking
Cons
- Costs a bit more than the N66C
- Needs a compressor and hose
DW66C-1 vs Bostitch N66C
They're closely matched — same nail range, similar weight, both with tool-free depth. The Bostitch N66C usually wins on price; the DW66C-1 wins if you want the DeWalt build and brand. Either is a great choice.
Who should buy it?
DeWalt loyalists and anyone who wants a rugged coil siding gun and doesn't mind paying a little more. For pure value, the N66C edges it. See the full field in our best siding nailer roundup.
