DEWALT XTREME 12V MAX Reciprocating Saw, One-Handed, Cordless Kit (DCS312G1) ; Visit the DEWALT Store. Best Power Reciprocating Saws based on Portability, Versatility, Light Weight, Mar 10, 2020 · With the new design, the Dewalt DCS312 12V brushless reciprocating saw is a little bulkier than the previous model. In the pistol-grip position, the brushed model was one of DeWalt Xtreme 12V Brushless One-Handed Cordless Reciprocating Saw (Tool Only) of exceptional quality and value. Guaranteed for life.Being able to use it with one hand and have the other hand free to hold onto a ladder is another benefit of this saw. I looked at the 12v models from DeWalt, Milwaukee, and Bosch, but they were nearly the same size and there is a world of difference in the power provided with 20v battery packs over the 12v ones.
