  • A specific tool for specific jobs
The price more than fair it's light weight but powerful and performed well in difficult positions and places

  • Works well within it's limits
Not bad for the size and power. Takes about 20 sec to saw through a 3" limb with a wood blade.. would give a 5 if it had a speed option. For wood you want it slower with a longer stroke.

  • Fantastic Tool
I needed a compact saw - I have a leaking water pipe and need to cut the existing pipe to repair. I needed something that would get into a very tight space. I have a Milwaukee 3/8" electric ratchet complete with batteries and charger, so I wanted just the Hackzall tool. This really fit the bill. The battery seems to last quite a long time and the tool has quite a bit of power. I also had to cut a 2x4 to get into the area - it went through quite well. This doesn't perform like my full size 110V Sawzall, but then again, I'd be shocked it it did. It came with 2 blades, one for wood and the other for metal. Each blade is 3" long. Perfect. ... show more

  • Good one handed operation
Needed this to work on soffits at the top of a ladder. Corded two handed Sawzall was too much risk and weight. This worked very well. It has more hand vibration than a full sized saw due to the weight. But the lack of a cord and the one handed operation are really handy. As is the small size in some locations. The short 1/2 inch stroke means that you may have to practice some sawing motions to help clear sawdust from thicker wood. Made fast work of PVC pipe in a remote location. Battery life is ok for short tasks. For all day stuff I would try to use a normal ac powered saw. Good addition to the tool box from a reputable company and at a good price. You need to already have another Milwaukee tool with identical batteries as this tool was sold in this listing without battery or charger. ... show more
