Do you need a strong impact driver to handle the toughest of jobs? Then it's time to go through the market and decide which one is right for you. There are dozens of different models and brands on the market today so you should not take this decision lightly. You can either be happy with your choice or completely dissatisfied. Buying an impact driver is an investment, so take the time to choose correctly. Here's what to look for:
Torque
Heavy Duty Drill
The most important thing to consider when it comes to choosing a powerful impact driver is its torque. To put it simply, torque is the strength and power of your power tool. Torque is measured in pounds-per-inch or in.-lbs. This is the pressure (in pounds) that your impact motor puts out per inch. So, if you're looking for a powerful impact, look for one with the highest in.-lbs. of torque. There are quite a few construction tool manufacturers that make them with high torque, including brands like Bosch, Ridgid, Makita, and DeWalt. I would consider any impact drill with 1400 or more in.-lbs. of torque as heavy duty.
Speed
The next thing you need to consider is the speed of the driver. The best combination is high torque and high maximum speed. Speed is measured in RPM or revolutions-per-minute. This is the amount of times your bit will spin around per minute. Look for an impact with a higher max RPM. This will help you drive those long screws through the hardest of materials at a faster rate. Any impact driver with 2200 or more RPM is considered fast.
Blows/Impacts
Also, don't forget to check out the BPM or IPM. It stands for blows-per-minute or impacts-per-minute. This is the maximum amount of blows or impacts the driver puts out. It's definitely something important to consider in this construction tool. The higher the BPM/IPM the faster you can drive screws or drill holes. 2500 or more BPM/IPM is a good amount for a heavy duty impact driver.
Other Features
Other things to consider in a heavy duty driver are the size, weight, balance, and battery charge time. These comfort and convenience features can make a big difference, especially on heavy duty jobs.
