Stanley Bostitch 2-1/2-in. Coil Siding Nailer (N66C-1)

Key Features

Built for Siding Nails

This coil siding nailer drives 15-degree wire-weld and plastic inserted coil nails from 1-1/4 in. to 2-1/2 in. That gives you the range to handle siding, shingles, sheathing, and fiber cement without switching tools.

Dial in Nail Depth

The adjustable depth guide lets you set nail depth quickly instead of fighting proud heads or overdriving. That matters when you're working on softer woods or finished surfaces that mark easily.

Light on the Arm

With a lightweight aluminum body and a net tool weight listed at 4.7 lbs, this nailer is easier to carry through long siding runs. Less weight means less fatigue when you're working overhead or moving around staging.

Overview

Bostitch N66C-1 2-1/2 in. Coil Siding Nailer is a pneumatic siding nailer built for installing siding, shingles, sheathing, insulation board, drywall, and fiber-cement boards with coil nails. This is a coil siding nailer designed for fastening exterior materials quickly with consistent depth and high magazine capacity. Model Number: N66C-1. If you want a dedicated air nailer for siding work instead of forcing a roofing nailer or framing nailer to do a job it was not built for, this is the right type of tool.

The big advantage here is nail compatibility and capacity. The tool drives 15-degree wire-weld and plastic inserted coil nails from 1-1/4 in. to 2-1/2 in., with a magazine capacity of up to 300 nails. On the job, that means fewer reloads and better pace when you're running long walls or repetitive fastening work. It also handles nail diameters from 0.080 in. to 0.092 in., which is the range contractors expect for many siding and sheathing applications.

The adjustable depth guide is one of the features that actually saves time. Instead of stopping to correct overdriven fasteners or leaving heads standing proud, you can tune the setting to match the material. That matters on softer woods, shingles, and fiber cement, where clean fastening affects both appearance and holding power. Bostitch also adds a soft rubber foot to help reduce marring on softer materials, which is a practical detail if you're working on visible finished surfaces.

From a build standpoint, the aluminum housing keeps weight down without turning the tool into a disposable jobsite piece. The listed net tool weight is 4.7 lbs, and that lighter feel matters more than people think when you're moving ladder to ladder or reaching across a wall. A siding nailer does not sound heavy on paper, but after a full day of repetitive use, lighter tools are the ones you still want in your hand.
