What to Look for When Buying an Impact Wrench
Buying the right impact wrench is a process that needs careful consideration of different factors. Let’s look at some of them and why they matter.
#1. Torque - It’s important to have a torque that is enough to remove a fastener. A higher torque translates to a more capable impact range. It’s better to go for an impact range that has a minimum torque of 150 foot-pound.
#2. Size - The smaller the size the better. However, you need to know that there’s a tradeoff between torque and size. Going smaller means that you sacrifice a little torque. But then, you get a tool that fits tight spaces and balances well in the hand.
#3. Weight - Depend on the duration of the project. For short-term projects, weight isn’t a huge consideration. However, long-term projects requires that you go lighter since that’s where fatigue begins to set in.
#4. Impacts Per Minute - The number of impacts generated per minute is an important consideration. A higher number lets you drive screws faster and loosens bolts much easier.
#5. Brand - Impact wrenches are manufactured different. That said, you need to buy from a trusted brand. Examples of brands to consider include DeWalt, Campbell Hausfeld, Portable-Cable, Ingersoll-Rand, among others.
#6. Warranty - You need to buy an impact wrench that’s got a descent warranty. Most manufacturers put a warranty of 1 to 2 years on their tools. But occasionally, you can get warranties that are much longer.
