I waited far too long to purchase my first impact tool. It has saved me hours.
These tools are incredibly handy for removing lawnmower blades in seconds, and also for removing the flywheel bolt so you can check the crankshaft keyway.
And have recently added a battery impact drill which saves me time removing many bolts I purchased Ryobi LLCDI18022 ONE+ 18V Cordless Percussion Drill/Driver with 2x 1.3Ah Batteries and Charger
This is an excellent choice as it is very powerful for a battery impact tool and also has the adjustable speed to help not strip any bolts or over-tighten.
Here’s a video of my Clarke impact tool in action
This is much smaller and more versatile for stripping parts of lawnmowers. It is very powerful for a battery impact drill and also has variable speed.
