Why The MiniTrencher SiBore SB431E Is Worth The Investment

This isn't just a boring drill, it's the combined best of MiniTrencher's SB216E and SB215E cordless models, giving landscapers and contractors 1-in., 2-in., and 4-in. bore capability plus extensions in a single Makita-powered kit instead of buying separate cordless tools for each size.

The SB431E specifically addresses the needs of landscapers, sprinkler system installers, plumbers, and electrical contractors who need the full range of common bore sizes with the convenience of cordless power, without owning multiple single-size drills.

One Cordless Kit, Three Bore Sizes, No Mud. The SB431E includes all the accessories of the 1-in. microBore model plus the 2-in. and 4-in. augers and extensions of the traditional model, powered by a high-performance Makita battery, and its waterless boring method eliminates the muddy mess and cleanup time that comes with water-jetting or mole-style boring tools.
