For in the field work it has its merits. As long as you realize that a drill guide is not a drill press, you will be happy. Because of the limited size of stock that this device will allow, it can not take the place of a bench top drill press.
So it solves a lot of my needs.2. It's hard to handle it when it's connected with the drill, because it weights almost the same as the drill. It's very hard or impossible to drill a hole near the edge of a wood sheet, I had to mount it in a piece of wood to get the work done.PROS:1. For aiming, you have to press a few times before getting to the right place so you can begin to drill.
CONS:1. Fairly accurate, much better than drilling with your bare hands.3. There's nothing like it in the market. The two top screws tend to loosen when your drill is making a little bit much vibration due to the nature of whatever you're drilling.
A laser beam would've helped a lot.4. Fair price, not too expensive.I didn't tested other angles besides 90ยช. You have to tight them after every hole you make, or the angle will change.2. I think they should've made it a little lighter.3.
The guide worked like a charm when drilling straight down into the floor. The plastic handle that screws into the base was flimsy and I had no faith in relying on it. I read the existing reviews on this items and have to concur. But it was awkward to hold securely when drilling into the wall. I felt much more safe pressing the base against the wall with my hand, which was awkward.It did in a pinch and was acceptable for the money, given that I do not foresee any immediate future need for it. The overall sturdiness suffers due to the plastic nuts and washers securing the rods to the the base. I removed and discarded the supplied tension springs because they required an insane amount of force to compress.I bought this drill guide as part of a bathroom remodel to make holes in the wall and floor for a pedestal sink.
The slide/chuck assembly has so much play it was not possible to hit a mark within +/- 1/4". This was purchased specifically to put holes in round stock. In short, this will not deliver anything close to an accurate perpendicular hole in anything. I could have done much better without it. The vees were not deep enough to hold 1" stock securely, but it sort of worked. However, the chuck was not centered over the vees, so holes were off position.
If I let the bit get too far the play between the bit and the frame was enough that the bit broke the plug while drilling. The drill guide worked just well enough for what I needed to do. If I had space I would buy a full-size drill press but attaching this to a piece of wood worked for now. I would imagine with hole drilling it would be somewhat the same and a small drill bit may break. The drill bit does wobble a little bit on the rails since they are a little too small, so delicate work is not recommended. I used it to drill some plugs for filling screw holes, and it worked as long as I did not drill too deep.
