Is the Bostitch N66C worth it?

For regular siding work, yes. It is light, holds 225 nails and drives fiber-cement reliably. If you only hang a few boards a year, a cheaper strip nailer or screws may be enough.

What nails does the N66C take?

It uses coil nails with a 2.1–2.5 mm shank and 32–64 mm length. Match the nail to the siding: ring-shank for fiber-cement, smooth or ring for wood.

What air pressure does it need?

Run it between 4.8 and 8.3 bar (about 70–120 psi). Start near the low end and raise pressure only until nails set flush.

Does it come with a case or fittings?

The nailer ships with the 1/4 BSP air fitting installed. Check the listing for a case, oil and safety glasses, since bundles vary.

When is the N66C cheapest?

The tracked new price has held at $225.00 at Amazon since November 2, 2026. Siding nailers often dip during off-season and bundle promotions, so watch the price history.

Our take on the Bostitch N66C Coil Siding Nailer

The Bostitch N66C is a pneumatic coil siding nailer built for fastening fiber-cement, wood and composite siding. It drives 2.1–2.5 mm coil nails from 32 to 64 mm long, holds 225 per coil and delivers 500 in.-lb. of driving power at 4.8–8.3 bar. At 1.99 kg it is light enough to use overhead, and its 1/4 BSP air fitting is the common shop standard. The best new price is $225.00 at Amazon as of November 4, 2026, the only new price tracked so far.
