As someone who is new to Industrial and Scientific drills, I was a bit hesitant to invest in cutting tools like this. However, my analysis of this product showed that it delivers on its promise of adjustable depth and precise countersinking for any project. The ease with which it can be set up and used makes it ideal for anyone looking to increase their drilling skills. The only con is the price point for someone who may not do a lot of cutting jobs.
Pros
Adjustable depth stop allows for precise and consistent countersinking.
Cons
Difficult to use for those without experience or knowledge of countersinking techniques.
Setting the depth exactly where you want it is a bit of a chore, but after that it seems to work great. I ended up turning the countersink by hand to cut a test hole to the correct depth, then installed the countersink into the hole and tightened the set screws when everything was in place. Until it slips and cuts holes to the same depth as it should.
