BOSTITCH Coil Roofing Nailer RN46 - Durable, Jobsite-Ready Tool

Our review of the BOSTITCH Coil Roofing Nailer RN46 finds it aimed squarely at roofing contractors and serious DIYers who need a durable, fast roofing nailer for repetitive nailing. The single biggest reason to buy is reliability on rugged jobs: the tool combines a lightweight aluminum/magnesium housing with a dry-fire lockout and carbide nosepiece so it stands up to abrasive roofing work while reducing downtime. This review focuses on real-world durability, loading convenience and how the RN46 handles long days on shingle roofs.

Key Features

• Lightweight housing: Magnesium/aluminum construction keeps the tool light for extended overhead work while remaining tough enough for jobsite abuse.
• Zero nail lockout: The dry-fire lockout prevents accidental dry firing and clearly signals when to reload, reducing wasted time and damaged materials.
• Carbide nosepiece: Carbide inserts on the nose extend wear life on abrasive shingles so the tool keeps seating nails consistently over many jobs.
• Single-action side load canister: The patented one-step side load lets roofers reload coils quickly without wrestling with the magazine.
• Adjustable depth and shingle guide: Quick-set depth control and an adjustable shingle guide make it straightforward to set nail depth and spacing for consistent results.
• Comfort and protection: Over-molded grip, wear guards and skid pads reduce fatigue and protect the nailer when dragged across roofs.

Who It's For

The RN46 is best for professional roofers and dedicated handymen who run dozens to hundreds of nails per day and need a tool built for continuous use and easy servicing. Its features favor crews that value fast reloading, consistent drive quality and minimal downtime caused by tool wear.

Less suitable are occasional users who nail only a few shingles per year or who need a multi-purpose framing or finish nailer; this model is optimized for roofing coils and the specific demands of shingle installation rather than general carpentry tasks.

Pros & Cons

Pros

• Durable lightweight housing balances a low weight with ruggedness for jobsite longevity.
• Dry-fire lockout and clear reload indication reduce misfires and lost time on the roof.
• Carbide nosepiece and wear guards extend component life on abrasive shingles.
• Single-action side load canister and adjustable guides speed reloading and layout work.

Cons

• Designed specifically for roofing; users needing a multi-purpose nailer should consider other types.
• As a dedicated coil roofing nailer, occasional owners may not recoup the investment compared with lighter-duty tools.
