Most new cordless tools really are made with pretty good modern technology. This new technology allows many of these cordless tools to work almost as well as their corded equivalents. So in today’s day of power tools, you should make sure you are evaluating your tool’s performance standard properly when considering getting a job done in an effective and timely manner.
For instance, with drills, the key to performance is being able to get the required torque at the highest speed. One of the most common misconceptions is the higher the torque rating, the faster the drill will complete an application. This is not always the case.
Torque is the force the drill produces to turn an object, not how fast an object will turn. Recently, torque ratings have been steadily increasing to levels beyond what is actually needed to complete applications. A new and more effective way to measure the performance of a drill is to combine speed and torque, which is in effect measuring power.
In the past, a drill’s power rating has been used as a tool to design products. It is not until now that it will be used as a new way of evaluating a drill’s performance level. Now power rating can be used as a direct indication of how fast a drill will complete an application. The drill’s power rating is measured by its Units Watts Out(UWO), the point where the drill’s speed and torque output are the highest. The higher the drill’s power rating, or UWO, the faster it will perform on the jobsite.
Neat explanation of torque for power tools, drills in particular. I just wonder if the salesman at Home Depot will understand me when I ask him about “UWO”
do you know if torque is measured by Lbs per inches or lbs per foot? For instance Home depots website says that their ridgid 18 V drill has 450 lbs of torque..
