Bostitch RN46-1 vs BRN175 Review

If you need a tool to assist you with roofing, which can easily pierce through fiberglass and asphalt, a roofing nailer may be for you. Roofing nailersare designed to help with construction projects and the nails a formatted to be removed every 20 years for replacement roofing. Bostitch makes two very similar roofing nailers that have a few differences you should be aware of before making a purchase. Let’s examine both of these nailers, and see which one would be the best choice for you!

Bostitch RN46-1 Roofing Nailer

The Bostitch RN46-1 coil roofing nailer has an operating pressure of 70 to 120 psi. This nailer is lightweight, at only 4.8 pounds, and has 410 inch-pounds of torque. This product is durable, with ideal usage in roofing, fiber cement, and exterior dry wall.

This nailer can drive 100 nails per minute during contact firing, which bounces across your workpiece for speed and accuracy. An integrated gauge to help with shingle spacing and control also accompanies this. Depth-of-drive adjustments can also be made easily with a 5-setting depth dial. This allows you to adjust the depth for your project, with countersinking and flush mount driving available.

The Bostitch RN46-1’s magazine holds 120 coil nails, from ¾ inch to 1-3/4 inches long. To prevent against dry firing, this product also comes with a zero nail lockout. The Bostitch RN46-1 also has a loading canister on the side, for easy and quick access during your work. Along with this is a carbide nose insert, to make sure that your tool lasts for years.

This product comes with wear guards and skid pads to protect against harder surfaces, along with an over-molded grip. This grip allows you to work no matter what the weather conditions are, and wherever you want to. The Bostitch RN46-1is also made from aircraft grade aluminum, to withstand any drops or falls on the job.

The Bostitch BRN175 roofing nailer is very similar to the previous product. This product weighs 4.8 pounds, and drives ¾ to 1-3/4 inch coil roofing nails. It comes with an operating pressure of 70 – 120 psi.

This product also comes with a depth adjustment wheel, similar to that of the RN46-1, which helps you maintain the depth you need for a variety of different projects. Like the previous product, the Bostitch BRN175 also comes with a shingle guide to get proper shingle spacing every time. This product also comes with a carbide nose insert, much like the RN46-1, to ensure tool longevity.

Unlike the previous product, the Bostitch BRN175 has adjustable exhaust. This feature makes sure that exhaust is never directed towards you while you use the product. This product also comes with a rubber grip, adding extra comfort during long-term use. The Bostitch BRN175 does not come with skid pads, however.

This product comes with two firing modes: contact and single. A dial is featured above the trigger, for your convenience, so you can switch between the two modesas you need to. Contact mode, similar to the previous product, also bounces across your work item for quick nailing. On top of this, you also have a depth-setting dial, ensuring that you have the adjustability you need for every project.

Both of these nailers are a great choice for roofing and other rugged, outdoor and indoor projects. If you have a necessity for skid pads, high durability, zero-nail lockout, and single-action reloads, then the Bostitch RN46-1 would be the best choice for your needs. If you prefer a more simplistic design, with adjustable exhaust and durability, then the Bostitch BRN175 may be a better choice for you. Both nailers come with single and contact firing modes, as well as a lightweight design and depth setting dials. Either of these nailers would be an excellent choice for your work and at-home project needs.
