Swim Time Guide Inground Drilling 5/8” Anchor Holes to Easily Install Your WardenWarden Pool Fence in Concrete, WWDG, 5/8-inch, Black

If you have a regular power drill with a hammer setting, you're probably going to have a hard time with this tool and the job in general. I started with a Dewalt DW511 knowing that it was under-rated for the job, but interested in how it would do. It shook the drilling guide apart (wingnuts jiggled off), and popped the upper bearing loose. It rattled around inside the "loose" bearings and I stopped before I got through the first hole. Then I switched to a Dewalt D25263K. Same bit, same concrete, same guide. It slid into the concrete like I was pushing on sand. The slight gap between the bearing and the bit was no longer sloppy, and the bearings were no longer contact surfaces for the bit, but guides to keep the bit straight for like 5 seconds while it effortlessly made its way to the bottom of the hole.

As expected

Got my job done ! Perfect

This is advertised to drill 5/8” holes for pool safety fences. However, the inner diameter of the bearings are bigger than 5/8”, so the bit does not sit plumb. This jig is worthless and shouldn’t be purchased. You might as well freehand the holes with the quality of this jig.

Exactly what it says. This assisted us in installing our Water Warden pool fence we purchased from another store but it did not come with the guide thankfully I was able to order it from here and it came 2 days later and it was extremely accurate and good quality.
