From the company that brought you the original Sawzall comes the Milwaukee 2420-21 Cordless M12 Hackzall Reciprocating Saw Kit with Battery. This handheld wonder-tool does the work of a traditional Sawzall, but in a lightweight and compact package. The 2420-21 can cut over 80 pieces of 1-1/2" PVC on one charge, and the 3000 1/2" strokes per minutes means that your cuts will be clean and smooth every time. It accepts both standard Sawzall blades and Hackzall blades, so you'll never have to worry about having the right blade for the job. Forget using a traditional Sawzall one handed, that can lead to not only an inaccurate cut, but an unsafe situation as well. The 2420-21 can be used with one hand safely and effectively, and the lightweight design means less fatigue even if you're using it all day. Once you've gotten it into that tight, confined space, the built-in LED will allow you to cast a bright beam of light on your cut zone for added accuracy and safety. And you can trust the proven power of the Milwaukee M12 Cordless platform to offer you the versatility and compatibility you need to get the job done.

From the first time we picked up a Milwaukee 2420-21, we absolutely loved this tool. It just felt perfect in our hand, and once we pulled the trigger it was obvious we were holding a winner. This saw feels as powerful as a full sized Sawzall, but is comfortable and easy to use with one hand. It produced clean cuts in PVC, metal tubing and a variety of other materials. And the best part is that it was compatible with all the M12 tools we loved so much. No surprise here, Milwaukee has once again raised the bar in the compact cordless tool market.
