Q:what is a good screwdriver tip set for this?
by|Apr 8, 2024

Answer This Question

A:  None since this is not an impact driver. It's an impact wrench that uses sockets only.

        Q:What size socket do I need for this? I just bought it and noticed my half inch dewalt deep impact socket set won’t fit through the hog ring. Bought DEWALT Impact Driver Socket Adapter Set (DWMT74741) and that doesn’t fit either.

            Incredible Tool. Highly recommend
            [This review was collected as part of a promotion.] I bought this tool in need of a strong compact stubby for my work in an automotive shop. I bought this tool because I was so impressed by my recently purchased Dcf900, dewalts new 1/2 in high torque. When I first used the tool I loved how perfect it fit in the hand, also the three led lights on the front. Being able to control the brightness of the leds and having 4 different torque settings makes all jobs easier. Probably my favorite setting is the precision torque mode allowing me not to completely back off nuts/bolts but also not destroying threads but screwing them all the way on. I was blow away by the performance of the tool zipping off rusty caliper bolts (high in the rust belt of the northeast) and getting in to hard to reach places. Amazing tool no complaints yet after 6 months of heavy use.

              Should have bought one of these years ago
              So far I have used to change the blades on my rider, without taking off the deck! This thing is so compact it fit under when the blade was on highest setting saving me a lot of time. I used to to remove spark plugs on an old v8 engine. I had one plug that broke off and I used this to get it out with an extractor. After I broke one I used this to get the rest out and they all came out without issue. I love how compact light weight and powerful this thing is, will be buying one for my dad as well!

                Pretty impressive for a compact
                Decided to pick up this 1/2 inch impact and so far I’m pretty impressed. I used it to do a brake job on my wife’s car and it had no problems taking the lug nuts off. I also love how compact it is, fits into tight spots to get hard to reach bolts. If it’s like all my other dewalt tools it’ll last a long time.

                  Excellent power. Compact size!
                  [This review was collected as part of a promotion.] Super easy to use. Extra power without using a ratchet. Love that it works with my other dewalt batteries and don’t need to have an extra charger laying around. Bought myself some deep impact sockets and this will be my new go to for any auto repairs and anytime I would’ve previously used a socket and ratchet. No job too big or small for this tiny but mighty wonder

                    Compact size with out sacrificing power!!!
                    [This review was collected as part of a promotion.] Very pleased with this impact wrench. At first I did not think it would be as strong as the full size but it was able to remove the hydraulic cover for my excavator with ease! Compact size without sacrificing power.

                      Crazy power!
                      [This review was collected as part of a promotion.] This impact wrench really packs a punch in a very small package, with a 6ah flexvolt battery it drove a 9" long 1/2" lag bolt into glue lam with no pilot! It has a great connection ring that is very sturdy and has held up to quite a few bit changes. Its been dropped, kicked, rained on, and still has the same power as when I got it! Very very impressed

                        Very compact
                        [This review was collected as part of a promotion.] This worked out perfectly. I needed to get some exhaust manifold bolts off in a tight space and this worked out perfectly. It's so compact I could get it right where I needed it and it had enough power to break them free. These bolts are known for snapping off and that was not the issue here. Having a bright light is a great feature as well.

                          Must have
                          [This review was collected as part of a promotion.] This is a great tool and a must have. From building decks to mechanic work, this power tool will get the job done. It is well balanced and has plenty of features to get the job done. From the lights to the variable speed, you will not be disappointed.

                            Buy this now, thank me later
                            [This review was collected as part of a promotion.] I got this as my daily go to for driving screws and bolts. Previously, I used a standard 20v impact with a 1/4" bit driver but was looking for brushless replacement . There are several key form features that make this thing great. The hog ring anvil is a super secure connection, it makes a very satisfying click when you lock a socket onto it. My previous impact gun used socket adapter which had alot of play in it. This caused me to drop a socket in a hard to reach area more than once. The secure connection to the socket on this hong ring anvil, will also give me piece of mind while working overhead securing bolts in truss work. The flat back to the tool is a great point of contact for your other hand, it allows great control when driving timber lock or other lag style screws into place. The belt hook is also wider and slides into place much easier. While this might seem trivial, having the tool feel more secure while it's not in my hand allows me to concentrate more on things like moving work material or climbing a ladder. This is the first tool of this series I have used that has the adjustable torque and light settings, and while I am still getting used the added feature my initial take away is that it's awesome. I purchased an adapter to take this back to a 1/4" screw bit, and given the compact form of this unit it still falls into the same profile as my old impact gun. Overall I couldn't be happier with this thing, and would highly recommend it.

                              DEWALT 20-Volt Cordless 1/2 in. Impact Wrench (Tool-Only)
                              I used to use a ¼” impact driver with a ½” adapter and sockets for tightening nuts or installing lag screws on building projects. Unfortunately, the socket adapters would break and I was always replacing them. I tried my Dewalt DCF899 20v impact wrench, but it got heavy very fast when I was using it overhead. I also didn’t need the 700 ft-lbs of torque it was capable of. I saw the Dewalt DCF921, I ordered it right away. This compact impact wrench provides about half the torque (300 ft-lbs) as the bigger wrench which is all I need, but more importantly it weighs only about 1/3 as much. Because of its compact size, it allows me to get into tight spots. Handy tool and works great.
