RIDGID Gen5X Reciprocating Saw R8642

Gen5X Reciprocating Saw

When Ridgid introduced the next generation Gen5X  combo kit, I was excited to get my hands on the reciprocating saw. Ridgid talked up the Gen5X permanent magnet motors saying they have great power, performance and runtime. The nice part about the kit is that the batteries are 4.0 amp hour Lithium-Ion batteries that can supply the tools the power to run longer. While there will be a debate on the Ridgid warranty, they do claim a lifetime service agreement; free batteries, free parts, free service and for life.  Read everything about the warranty and follow the instructions exactly.

Ridgid Recip Saw Specs:

  • 1-1/8 inch stroke length
  • 0 – 3,000 SPM no-load speed
  • On/Off orbital action; orbital action for wood-cutting and demolition, non-orbital for cutting metal

Look and Feel

Ridgid_Gen5x_Side1When you pick up almost all of the Ridgid Gen5X tools, you will notice most of the tool is covered in a nice textured rubber over mold. The reciprocating saw is no different. The saw’s look and feel is great. The variable speed trigger is easy to use and the tool is comfortable with bare hands or with gloves. The switch to engage or disengage the orbital cutting for wood is very easy to use and hard to miss.

There have been some upgrades in the Gen5X reciprocating saw from the previous model. First, this model is a bit slower with 3,000 stokes per minute compared to 3,600 strokes per minute with the older model. The reason for this is because Ridgid increased the stroke length from 3/4″ to 1-1/8″ to make for a better and faster cutting saw.

The adjustable shoe on Gen5X reciprocating saw is nice because it will allow you to make blades last longer. However, it is only supported on one side and in some ways seems like it could be easily bent if the unit was dropped. Adjustment is easy and I would rather have this over a non-adjustable shoe. I just wish it was a bit more beefy.

Power Vs Vibration


The orbital setting makes cutting wood during demolition fast.  I enjoyed being able to change back and forth depending if I was cutting metal or wood.  With longer flat cuts the orbital setting really shines and allows you a lot less fatigue than with a standard straight stroke.

The one thing that I could really feel was that there is not a lot of dampening or anti-vibration in this tool.  It really stood out when I was using two of these tools from different manufacturers at the same time.   The vibration should only be an issue if you use it over an extended period of time.  In our case, we were trying to cut up the framing of a deck that was not framed correctly.

The power of the unit to be pushed through wood or metal is pretty impressive and battery life is on par with the other brands we were using on the deck.  This is not a brushless motor, but performance and battery life were close to some of the upper end models we were using.  While most of everything we were cutting was wood filled with screws, we really had to push the saw to get it to slow down.  Ridgid’s motor improvements include much better torque.

The Gen5X reciprocating saw is a bit heavy and it was noticed over a long day, but it is still lighter than some of the corded models of the past.  The extra rubber grips help to control the power and weight.


Overall, the saw is an improvement over older models and is a nice tool in the kit. There are many features included on the saw that do not come standard on others in this price range.

    • I wish we knew. We want a brushless sawzall and a brushless impact wrench.

      I just bought a Gen5X brushless model, the r8643. It’s a little heavier and noisier, and more vibration prone than the X4. I don’t know if it’s any more powerful than the X4. The shoe is modified so the support on one side is removed, however the shoe’s metal is thicker to support this change. Overall the shoe & shoe latching mechanism doesn’t feel as crisp as the X4. The tool itself seems more rugged, at least it looks that way. Overall I’d say it compares pretty favorably with the competition.
