Bostitch RN46-1 Coil Roofing Nailer – Lightweight, Durable, 3/4 in to 1-3/4 in

Overview

The Bostitch RN46-1 Coil Roofing Nailer blends a lightweight magnesium body with rugged durability, making it suitable for roofing, exterior drywall, insulation boards, and fiber cement applications. Its balanced design helps reduce fatigue during long days on the job, while rugged components stand up to abrasive surfaces.

Power, Speed, and Control

With up to 410 in-lbs of drive force at 100 psi, the RN46-1 delivers consistent nail placement. It can drive up to 100 nails per minute and offers two firing modes: a fast contact trip for broad coverage and a precise sequential trip for finish work. For shingles, an integrated tool-less gauge helps maintain even spacing across rows.

The tool is designed for practical versatility, supporting nails from 3/4 inch to 1-3/4 inches and enabling flush, shallow, or countersunk drives via an adjustable depth dial with five settings. This flexibility helps users tailor performance to material and surface conditions.

Loading, Downtime, and Convenience

Reloading is quick and straightforward thanks to a patented single-action side-load canister and a high-capacity magazine that holds up to 120 nails. A zero nail lockout prevents dry firing and clearly signals when a reload is needed, keeping work moving. The nosepiece features carbide inserts for long life, while wear guards and skid pads protect the tool on abrasive surfaces. The over-molded grip provides comfortable control in varied weather conditions.

On the job, these features translate to fewer interruptions, smoother operation, and consistent drive quality across tasks such as siding installation, vapor barrier work, and fiber cement projects. The RN46-1 is built to withstand demanding environments while remaining easy to maneuver for extended periods.
