Hi guys! Alright? Today we are going to talk about… This manual impact wrench from Megadora Impacta, from Vessel brand. I'm going to explain the characteristics of this key, show it at work and explain why I think you should have such a key. So let's go to the video! Vessel is a century-old Japanese brand in the production of tightening wrenches. I talk more about the brand's history in the video of this Megadora 900 switch, as well as all the explanation of the difference between the Phillips standard and the Japanese JIS standard. If you still don't know, take a look at this video and I'll leave a description. This is the Vessel Megadora Impacta model 980. It is from Vessel's Megadora line of keys and has a dedicated system of the company's 12° turn, when it receives the impact.

The purpose of this wrench is to facilitate the removal of screws that are rusty, locked or until they are dusted. Wait a little longer and I'll show you in detail how this mechanism works. In addition to the key model here at the top, some product information here at the front. The information that it should not be used to leverage. That it's made in Japan. And that it has a patent pending. Here at the back, some more information about the key features and instructions for use. Vessel has this key in five model sizes. This is the P.2 model, 100 mm rod. It is also size number 2 with a 150mm shank. A P.3 model, also with the 150 mm shank. And in Europe, two more models: a 100mm PZ2 and a PZ3, or PoziDrive number 3, with the 150mm shank. An interesting point of this Vessel package is that for you to take it off, you just have to do a turn, pull it here and then remove this necklace. So let's go here for the key details.

As I mentioned in the Megadora 900 video, this cable has a very nice feel to the touch. It is an extremely comfortable grip , it fits very well in the hand and also has a great grip. The cable is made of two components, this dark part being an elastomer and this gray part a recycled resin. Vessel uses the color of the cables to identify the models in the line. The Megadora 900 uses this greenish color and the 980 Impacta is identified by this gray color. The handle has this hexagonal shape and on three of its sides has this anti-slip region for greater grip. The manufacturer informs that this model can achieve a touch up to 26% greater, than common cables, in a scenario of use with oil. Vessel reports that it can achieve a torque of up to 2.9 Nm with this wrench. The hexagonal cable system also helps, to some extent, in anti-rolling. The key, when positioned on the table, keeps the tip off the floor.

And here on the back, the metallic region that will receive the impact to trigger the mechanism. Note that she already has some marks here from the hammer, but no part of the chrome came out. Moving on to the rod here, the first thing you notice is the grain you find in this chrome. Normally the common chrome keys, they don't have this porous visual aspect. Comparing here with the Megadora 900, observe how the Megadora 900 itself has a slightly less grainy look than the one from Impacta.

The shank is made of chrome vanadium and has a black tip that increases accuracy as well as strength. Comparing here with the tip of the 900 model on the right, note that this model from Impacta does not have the Jaws Fit feature. Observe the little wear here on both ends over about 6 months. Another very important point that these Vessel keys have are the tips in the JIS standard, which is the Japanese standard. Contrary to what most people think, when you see a view like this of a cross-slot screw, you imagine that they are all the same. And mainly, that they are of the Phillips standard. But this screw, it follows the JIS standard. Look at this little ball down here, which tells you that this screw doesn't use a Philips pattern, but a JIS pattern. It is very important to remember that Phillips wrenches, they do not fit this type of screw.

When applying force, the key easily escapes. Standard JIS wrenches work on both JIS screws and Phillips screws as well. I explain this difference and the pattern in more detail in the Megadora 900 video. And like all standard JIS Vessel wrenches, the fit on the Phillips screw is very tight. A point that impressed me a lot about this key was the strength of the magnetism of the tip. The Megadora 900 comes with a magnetized tip. But the strength of Impacta's magnetism is impressive! Note that when fitted, even with a lot of force, it does not come out of the tip. Look at this impressive screw attraction test here! Let's now explain the impact system. Unlike an ordinary impact wrench, which has the rod fixed here from the beginning to the end of the handle. Vessel developed a mechanism, in which the rod is actually mobile. The mechanism consists of a free rod, which when actuated by the impact at the end of the cable, uses this energy to press a spring and causes the rod, which has a pivot, to slide along a rail until it makes a 12-degree bend.

In other words, for each tap that you make here at the end of the wrench, the rod turns 12° to the left and returns to the same position. In the instructions for use, Vessel advises that you must firmly grip the cable, exerting a force towards the loosening and applying the impact, at the end of the wrench. This will cause those screws that are locked to move towards loosening. She also emphasizes not to use this type of key on thin surfaces, or that are more fragile, such as aluminum.

Let's move on to the measurements of this key here. The key has an overall size of 210 mm. Being 10 mm of rod and 11 mm of cable. The cable thickness is 33.8 mm. From the impact area, 18mm. And the rod, 6.4 mm. The weight of this key is 136 grams. Comparing here with the common model, it is around 45 grams more. Just out of curiosity, the Wera impact model has 127 grams. In other words, this model, which also includes all this internal metallic mechanism, has practically the same weight as a key without this mechanism. Now I'm going to show you it in practice! I put this blue tape on, so that you can see in a better way, the rod's rotation with each beat.

So let's go now to the final conclusions. There are manual impact wrenches on the market that are specific to this job. And this model is not intended to completely replace these keys. A specific impact wrench system may perform better than that wrench if you are going to use it constantly. But it's a big, heavy system that you always need to carry with you. This key, in addition to being light, has a greater reach and the versatility of being able to be used as a normal key. And as a final differential, with this wrench you don't have to worry if the screw is Phillips or if it's JIS. It's definitely a very versatile wrench, which you can carry in your tool bag and will help you if that screw you need to loose appears. And if you're arriving now and haven't signed up yet, Sign Up!
