Drilax 5/8-11 to 3/8 inch Drill Adapter Attachment, Threaded Arbor Shaft for Diamond Hole Saws and Sanding Tools, 5/8-11 Male to 3/8 Triangle Shank Professional Results for Home Renovations DIY Jobs

The only negative I can report on this item was the long shipping time. Other than that this adapter attachment works as expected. It is a very high quality product.

Well made

This works just fine as an adapter to a 3/8" drill. I used the arbor for a masonry wheel to clean up a concrete slab edge. One has to laugh at the folks who attempt to use this as an adapter for a core drill, try to drill 6" holes through concrete, then rate the small adapter one star. They probably rated their 3/8" drill one star too as it went up in smoke... This adapter is great when used appropriately.

You need this tool to change arbor sizes on some DeWalt tools.

Was hesitant based on a prior review, but put my faith in the seller. It fit my 3/8" drill just fine with the chuck open all the way. Perhaps the other reviewer may own a 1/4' drill ? Unit arrived on time, and the quality of the material & workmanship is very good. My need is quite simple - want to attach a wool buffer pad to a cordless drill I already own, to wax my car.

Summary: Adding a few grab bars to dad's shower. I used a lot of products for this project, so including all related products in this review. Recommendation: 1) When mounting grab bars, it's always easier if you can find the stud to attach to. In this vertical install, I decided to use a stud and Wing-Its anchors; partially because I wasn't sure I could hit both, and didn't want to put two fasteners vertically (on either the right or left only), but that would also position the bar in the shower a little too far in (towards the shower control). 2) The WingIts requires a 3/4" hole through the mounting material. For tile, this can be especially challenging. I used the SHDIATOOL diamond 3/4" bit, with the DRILLAX adapter to get through the tile, and then used the 3/4" BOSCH bit to finish through the dry wall. Also used the BOSCH bits for the other small hole. Having the right tool for the job is the difference between project completion, and a messy, disaster.
