The motor will protect the engine from burning up or other mechanical failures, allowing you to work with the tool longer without worrying about overheating.

This tool also comes with a variable speed trigger that allows you to control the speed of the saw’s stroke using speed control. This feature is handy to help you cut different materials at different speeds to get the smoothest cut.

Special note

This Milwaukee reciprocating saw is a well-thought-out, ruggedly built saw that gives good service life. However, like many high-end products, this high-level performance comes at a price, but it is worth it.

Using only high-quality blades for the best work output is also essential.

Frequently Asked Questions

Question: Why is the 15 amp better than the 11 or 12 amp? What more can it do?

Answer: They make a 12 amp model, not an 11 Amp. The 15 AMP has more brute power when cutting and further can maintain its momentum under more significant stress. It will not slow down or bog down.

The unit has a clutch that will disengage the unit and a dial control that allows you to reset the max speed of the blade.

Additionally, it has an orbital feature that adjusts the blade’s stroke from straight up and down to a circular motion (orbital). This allows for faster tearing and cutting.

Question: Does this saw come with a battery and charger, or are these sold separately?

Answer: The Milwaukee 6538-21 15-Amp Super Sawzall Recip Saw is a corded option. However, if you want a cordless option, we recommend the Milwaukee 2620 20 18-Volt cordless Sawzall reciprocating saw.
