The Nm is a unit of torque and a short form of the newton meter. Sir Issac Newton developed the concept of torque. So, according to his name, it’s called newton meter. What is 400 Nm torque mean on an impact wrench? The higher the torque, the more powerful the tool. Most of the 1/2-inch impact wrenches have a maximum torque of around 400 Nm. However, some 1/2-inch cordless models are designed for more demanding applications and can generate up to 600 Nm of torque. If you need a car to tow a trailer or caravan, you’ll need the extra strength of a high torque engine to help pull the extra weight.

For most applications, a 400 nm torque wrench will be sufficient. However, if you’re working with particularly stubborn bolts or are worried about stripping them, you may want to consider a higher-powered model. If you want to convert kgf-cm to Nm, all you need to do is multiply the first value by 0.09807 - one-hundredth of the gravitational acceleration of Earth:Regarding impact wrenches, the power and torque rating is among the most important considerations. More power means that the wrench can loosen more stubborn bolts. While more torque results in less likelihood of stripping the head of the bolt. Supplied with a traceable calibration Certificate allowing end-users to adhere to more stringent quality control processes New design handle is ergonomic and constructed from a soft grip material for comfort when using and enhanced grip Finally, it’s also worth considering how much space you have to work with. If you’re working in a tight space, you’ll need an impact wrench that has a smaller profile and is more compact. The first is the bolt size you’ll be using it on – impact wrenches come in different sizes and capacities, so it’s essential to ensure that you’re getting one that will be able to handle the bolt you’re working on with.

J/rad are also alternative units of torque, commonly used when you need the value of torque in calculations of work or power. These units are equivalent to Nm: Specifications ½" push thru sq dr 60 - 340 Nm / 50 - 250lbs.ft Length: 593mm Weight: 1.48kgSupplied in blow moulded box Specifications ½" push thru sq dr 60 - 300 Nm / 50 - 220lbs.ft Length: 593mm Weight: 1.42kgSupplied in blow moulded box Torque, simply put, is a measure of how much force is required to turn an object. When applied to tools, it measures how much power the tool can generate. A tool that produces more torque generally means it will provide more power and better performance, mainly when working with larger or more stubborn objects.

Ideal for use by professionals such as plumbers, electricians, engineers, mechanics, construction workers as well as DIY enthusiasts It’s worth noting that engines producing much more than 400 Nm (295 lb/ft) of torque, whether petrol or diesel, are usually at their best teamed with an automatic gearbox. Beyond 500 Nm (369 lb/ft), most engines come with an automatic gearbox anyway since they’re better able to cope with an engine that strong. Does torque affect fuel economy? Kilopondometer is another unit of torque and energy, abbreviated as kp⋅m or kgm. This means the force applied to one kilogram as a result of gravitational acceleration: Yes. Low torque engines are less economical because they have to work harder than high torque engines. That’s why diesel cars are a good choice if you take long, high-speed motorway journeys. They will be much more fuel-efficient than a petrol car. What about electric cars? Do they have lots of torque? In general, cordless power tools have less torque than their corded counterparts. Because the cordless models usually rely on battery power, and an electrical outlet supplies power to a corded model. However, there are some high-torque cordless tools available for heavy-duty tasks.
