Questions & Answers

Tightening foot pounds for 3/8 sub compact
ByOct 18, 2026
1 Answer | 
Answer This Question

Hello, Steve - Impact wrenches are not intended to provide an exact fastening torque. For applications with a specific torque requirement (such as lug nuts or engine components), it's best to snug the fastener with the impact wrench and then finish with a calibrated torque wrench set to the manufacturer's specification. If you need further support, then feel free to ask another question. You can also contact us by phone at 1.866.539.1710, Monday - Friday from 9am to 6pm (EST), or via email when you visit us at https://register.ridgidpower.com/contact.

          Advantage of a brushless motor
          ByDec 28, 2024
          2 Answers | 
          Answer This Question

          Brushless motors offer several advantages over traditional brushed motors: * **Longer lifespan:** Brushless motors don't have brushes that wear down, resulting in a significantly longer lifespan. Less friction also means less heat buildup, further contributing to durability. * **Higher efficiency:** Without the friction of brushes, brushless motors convert more power into rotational energy, making them more efficient. This translates to longer runtimes on battery-powered tools and lower energy consumption for corded tools. * **More compact and lightweight:** Brushless motors can be smaller and lighter than brushed motors with comparable power output, making tools easier to handle and maneuver, especially in tight spaces. * **Quieter operation:** The absence of brushes reduces noise and vibration, providing a more comfortable user experience. * **Greater power and torque:** Brushless motors can deliver higher power and torque for demanding applications. They also offer better speed control and responsiveness.

          Hello, Patrick - Brushless tools have more power, longer runtime, and longer motor life. Brushless motors not only deliver more power but are also lighter and more compact than brushed motors, allowing you to work longer and more efficiently.

                      It’s an alright tool I just wish there was more power in in that’s about it
                      by
                      Bought this wondering how often I would actually use it. Within a couple days of purchasing it, I had to replace a transmission belt on my lawnmower. This 3/8” impact wrench saved the day. The impact was enough to break the bolt loose on the main pulley coming off the engine without having to brace the pulley to keep it from spinning. Worked great changing the mower blades, too. Compact to fit into tighter places, yet powerful enough to get the job done. The LED lights are an added bonus. Highly recommend!

                      Warranty department is a zero
                      Warning: Watch out when purchasing a Ridgid power tool product. The warranty is a painfully experienced one. I purchased a 3/8 impact a year ago and finally got it out to use it, but it had no power. I tried three different batteries, and none worked. I've been dealing with the warranty department for half of my day with very little help. It has been a nightmare to deal with. I have multiple tools from Ridgid, and this is the first and last time I will deal with their warranty department. Very bad experience!

                          Beefy 1/2" impact
                          This is a beefy, large 1/2" impact. Be aware all of your 1/4" stuff will NOT fit this guy. But we are working on large steel buildings and this impact has the umph to tighten large bolts. Double check the tiny screw on the clip, mine fell off promptly but these things are constantly doing that. Great addition to my Ridged set, all my batteries are still going strong after 3 years.

                          Awesome tool
                          This RIDGID cordless impact wrench packs a punch. It has 250 pounds of toque. The balance at the grip is stable and easy to hold. It takes a 18 volt battery . It has a compact size and fits into smaller areas. It has 3 speeds and a auto tightening mode so you don't over tighten or under tighten your work. It has a tri beam light that lights up when you are using it. It has a 3/8 anvil connection. Very sturdy and handy tool.

                          Lightweight and small, convenient to carry around and not causing fatigue
                          The RIDGID 18V subcompact ½ impact wrench is lightweight with a small footprint, but still has a strong punch with a 225 ft/lbs of breakaway torque. I used it to take the tires off of a truck and car, and the breakaway of the lug nuts was quick and easy. I also used it to install TV wall-mounts and it worked like a charm. You need to use impact rated sockets so that they don’t break. One cautionary point is to check with your hand or with a torque wrench after fastening the lug nuts with the wrench. I needed to apply 90 lb-ft torque on the lug nuts, so I did some of it manually. What I really like about this impact wrench is how lightweight and small it is, making it very convenient to carry around and not causing fatigue.

                          Compact well balanced variable speed 3/8" impact wrench with three speed ranges and an Auto mode
                          This is a really outstanding 3/8" drive impact wrench. I would call this mid-torque. It is not for taking lug nuts off a cement mixer! It is super handy for medium applications where the compact shape is needed. It is very compact (in diameter and in depth) and has three bright LED lights spaced around the nose to illuminate your work without any weird shadows. It uses a friction ring to hold the socket in place. I got it as a bare tool - it uses RIDGID 18V batteries, which I had already, so this makes for a very good value. The balance of the tool is great, very neutral in your hand with a battery attached. It comes with a metal belt clip (I don't always use it on an impact - I do like them on the drills). It can be removed easily and can also be mounted on either the left or right side depending on which side you want to hang it. The impact has three speed settings and an automatic setting called "A". Setting 1 is low. Setting 2 is medium. Setting 3 is high. Auto mode "A" is useful and does different things in forward and reverse. When you are removing a fastener in auto mode it will impact on high until it starts spinning then slow down. If you are tightening in auto mode, it will spin on quickly then stop when it begins impacting to avoid over tightening. The tool is variable speed - it goes faster than more you pull the trigger. In low (1) max is 800 rpm. In high (3) it maxes out at 2800 rpm. If you register your tool, you can also get their lifetime service agreement.

                          Small yet powerful
                          I chose this Ridgid Lithium ion 3/8” impact wrench because of the reputation 0f Ridgid tools and for its compact size. There have been many instances where I couldn’t use my existing impact wrench because of it’s length. The Ridgid impact is a full 2 inches shorter, making it possible to fit in smaller areas. It has 4 torque settings, including an witch I have found useful. The 2 aH battery also has a level of charge indicator. This tool has a great deal of torque, especially for it’s size. As a test I removed the wheel nuts on my full size Jeep, and the had no trouble breaking them free. It comes complete with a charger, battery and carrying case.
