          A great implementation of a great tool.
          I am a bit of a fan of Rigid tools, especially their cordless tools. This cordless reciprocating saw keeps with their high standards for fit, finish, ergonomics, ruggedness and quality. It has great power and heft making it very efficient for the task. I’m a fan of its locking features for both blade and trigger. It makes a great additio. To my tool collection.

          Cordless convenience
          We already had a reciprocating saw but it is corded and not so easy to use in certain applications. The RIDGID 18V Cordless Reciprocating Saw is battery operated and makes using it so much easier because you can literally take it anywhere. The saw comes with one woodcutting blade. It has a convenient side lever keyless blade release that's easy to access. It has a lifetime warrantee on parts and service if registered within 90 days.

          Terrific cordless reciprocating saw!
          My husband loves his new RIDGID cordless 18v reciprocating saw. He said it’s powerful and well-made. The handle has a good grip material to make it easier to hold while using. The saw blade is easy to insert and remove. You’ll need to purchase the battery and its charger separately. RIDGID provides a “Lifetime Service Agreement” for the reciprocating saw and its parts with details on their website.

          Sawzall Recepricating saw
          Another Ridgid high quality tool, very easy to use and care for, light weight and very easy to use. I use mine for demolition work, cutting branches off small trees. The blade is very easy to change and is compatable with all sawzall blades. You need to hang on tight when cutting steel studs or pipes as it wants to jump and get stuck. So nice to have battery power and no cords. This is the only way to go now.

          Excellent No Frills 18V Recip Saw
          The Ridgid R8646B is TOOL ONLY and represents the solid, but no bells and whistles two-handed cordless reciprocating saw in the Ridgid lineup. It is lightweight, yet powerful. Blade changing is tool free with a blade clamp lever on the side of the body. Extending the Pivot Foot requires a 5mm Hex Tool (not included). The body of the saw is covered with soft over-molded textured grip. The saw is easy to hold and hang onto.

          Great Saw For Those Unique Jobs
          It’s fall in the Midwest and time to safely trim the trees. My old corded reciprocating saw died last year and it’s time to upgrade to battery power. Since I already possess a Ridgid battery powered circular saw I decided to go with this saw. I attached the battery after removing the saw from the box and noticed how well balanced it was. The saw grips well and runs quiet. The blade loads easily with the flip of a thumb switch. A safety lock prevents the trigger from activating. This will be a nice addition to my power tool box.

          Love this saw!
          I'd had a corded reciprocating saw for a few years now and it's really nice to have, but this cordless Ridgid reciprocating saw is super convenient. I'm doing a reno on an old house and there are countless times I've needed a reciprocating saw and there was no electricity available where I was working. Also, working on a ladder, you don't want to be dragging a cord with you up a ladder. This saw has a good, ergonomic design and it comfortable to grip. It has a on/off switch on top and a quick release blade changing mechanism that makes it super easy to switch out the blade. It also has a locking feature so that the saw cannot be accidentally turned on I suppose. This doesn't seem to be covered in the manual. At least I didn't see it anywhere, but who knows. I thought it was to keep the blade running without having to hold the trigger down, but I couldn't seem to get it to work that way, so I figured it was just to prevent accidental turning on like if you threw it in your tool box and the trigger got hit. It seems to have good power. The blade that comes with it is rather short, something you might see in a jigsaw or something and it didn't seem to cut a metal screw off very well, but I'm sure a different blade would work better and they look like it will use a universal blade design. I think they need to improve the manual a bit to cover the lock on the handle more clearly.

          Very nice cordless saws-all with capability equal to my plug-in Saws-all.
          This is an excellent addition to my RIDGID 18V tool collection. Since I already have a 4AH battery that came with my 1/2" hammer-drill, Tool Only was a good way to go. The saw (with battery attached) is well balanced and a nice balance of weight to be heavy enough to control vibration but not too heavy to use for extended periods. It has tool-less blade changing that works great and a trigger lock which is a nice safety feature. I used the blade that came with the saw to cut a 1" thick piece of dry red oak and compared cutting efficiency to my older corded Saws-all. The 2 tools were comparable with this saw cutting slightly faster. The advantages of a cord-less tool will make this my go-to saw unless making more cuts than the battery can handle which is rare. I did not determine battery life but I don't expect it to be an issue since I don't tend to use this type of saw for extended periods.

          Let's you focus on cut line straightness in total absence of binding.
          Power reciprocating saw is even more universal than manual hack saw. You can cut everything from drywall panels to steel pipes using appropriate blades. This tool comes with wood blade (lower number of teeth per inch or TPI). You can still use this blade for drywall and even large PVC piping. Tool has quick blade disconnect. Some people complained that blade gets stuck. But I found that you just need to slightly lift the blade when you push release lever to easily release it. Blade lock is non-proprietary and you can use blades from other brands. As with other Ridgid tools I like hybrid plastic/rubber material that offers no slip grip. Tool is especially great for drywall cutting. Comparing to manual drywall saws it let's you concentrate on straightness of the cut. With manual saws you often have to wiggle them to unbind and hence loose control over straightness of the cut. As for ability to cut in contrained spaces I have an older corded reciprocating saw that I even used for cutting stump roots. I was lucky that this stump was within 100ft of an electric outlet. This saw has brushed dc motor and this is for a reason: very high starting torque. You almost always start the saw when teeth are already in contact with material and you need this high torque to avoid binding. Would it be a table or miter saw that needs to spin up first before teeth touch material brushless DC motor would certainly win efficiency game. This is beacause brushless motors in power tools has no rotor position sensor. Reliability wise carbon brushes live longer than even simple brushless motor controllers at least in my experience. Even if brushes are done they are cheap and easy to replace. Failed brushless controller is more expensive than brushless motor itself and those controllers are mostly non-serviceable.

          Ridgid #R8646B Reciprocating Saw
          The Ridgid model #R8646B a heavy duty, professional reciprocating saw that is excellent for use by the contractor on the jobsite or the homeowner in doing wood or metal demolition work. This tool is a just the reciprocating saw (tool body only) meaning that does not come with the rechargeable battery and charger so that saves you money in the long run without duplicating these two RIDGID items if you have them already. The saw uses the 18-volt Ridgid removable rechargeable battery and charger (sold separately) and it is100% compatible with all other 18-volt Ridgid tools such as, but limited to, impact, bandsaw, jigsaw, drill, radio, oscillating tool, etc. This saw features a simple lever keyless blade holder for easy installation and removal of the reciprocating blade without the need of a screwdriver, wrench or hex key! Just by squeezing the handle trigger, the saw can operate the saw from 0-3,000 strokes per minute. The variable blade speed is great for starting, during running, or ending your cut into wood or metal without having the saw jump around as you cut as it gives you control of the cut. It also has a powerful back and forward 1 1/8” cutting stroke length which thrusts the cutting blade in the wood or metal. It has a pivot changing position shoe assembly that allows you to stabilize the saw directly at any angle on the work piece. It has a nice simple slide lock handle feature, that you can activate, so the tool does not accidently turn on and drain the battery while tool is being transported and when it is not in use. This reciprocating saw comes with the Ridgid Lifetime Service Agreement, you must register the product online with 90 days with a Home Depot receipt, that covers free repair service, replacement parts for the life of the tool. The saw comes with complete operating instructions, charging instructions, and a wood cutting blade. Other wood and metal reciprocating cutting blades are available at Home Depot. Made in China. You can always count on the Ridgid brand for quality tools as they will always meet and exceed your performance expectations when it comes to your power tool needs!
