The durable and lightweight BN31M1P is equipped with a number of quality-of-life features that make it ideal for all-day use. The tool comes outfitted with a last nail lockout, which reduces wear on the tool and indicates when to reload. Additionally, SENCO's oil-less design saves the user the hassle of oiling the tool prior to use, saving you time and money. Capable of driving 18-gauge brad nails from 5/8" to 2-1/8" in length, this nailer is ideal for finish and trim applications where you want the power to drive through dense materials without splitting the work surface. Includes couplers, wrench and case.
