37 TORQUE THE TORQUE...

We are potentially going to be painting 16 alloys, which is a lot of unscrewing and screwing of bolts, so I was thinking of investing in a cordless drill to help ease the burden.  After some research, it turns out that I need an impact wrench, not a drill.

What is the difference?  I didn’t know either.  After digging, it looks like impact drivers generate bursts of torque by releasing energy from a spring; a drill provides a steady turning force through gears. 

An example I found online goes, “Picture placing your hand on a brick wall and continuously pushing - that's how a drill delivers power.  Imagine punching the wall; that's how an impact driver works.  One applies a constant 'push,' while the other delivers quick, sharp ‘punches.’” Impact wrenches deliver more torque than a drill, which is why they are used for heavy-duty tasks such as removing wheel nuts.

Right, got it. So, where do I buy one of these fancy devices? B&Q, that's where. For £100, I can pick up a Ryobi ONE+ 3-Speed Impact Wrench 18V, which is cordless and has a battery that can be used in other devices.

Do I technically need one of these devices, probably not.  Do I want one, oh hell yeah!!!
