I made cutting boards and really didn't want to use a jigsaw to cut holes. I ended up getting this to make the job easier and OH BOY DID IT! My cordless drill/driver got through plywood with no problems. I even had to stop in the middle before it sank to take a picture simply because I was so impressed with how well and quickly it worked. This saved me tons of time and you can skip the compass by drilling a hole and sawing it out with a jigsaw or by hand. Just mark where I wanted to make the hole and BOOM. DONE! It worked great! I'm so glad I got this, the corn boards turned out great!
