My best friend and training partner works for a German drilling company. I love visiting him in his office and look at the different kinds of drills. Right now, I have two cordless drills which I bought from him with a 50% discount. He would also lend me his heavy duty drills whenever I have to drill through hard concrete walls in our farm. He also lent me his laser guided measuring device. It was a fun experience and I really had a grand time working with it.

Until recently, I didn’t know that they were different kinds of drills. I thought they were only two kinds: cordless drills and heavy duty drills. When I had to go through concrete and adobe in our farm, I tried to borrow a jack hammer but he said his heavy duty drills can do it. Good thing my best friend was patient enough and explained to me the difference between chipping, drilling, demolition, and all other handyman tasks that requires specialty tools.
