I like the variable angle of this. I was drilling holes through 6x6 newel posts for stairs that were 35 degrees. The exit holes on the opposite side of the posts were at most 3/16" off center. If that's accurate enough for you, then this will do for you. The drill scraped the inside of the guide so after about 30 holes the accuracy goes out. So, it's good for about 2 or 3 jobs. They could have made the base and the guides 2 X as long for better accuracy. I found something similar at Lowes but, it also was too thin. This tool was not designed by a carpenter. I think it was designed by someone who knows how to click a mouse on a 3D printer.

Great tool. Not sure how I could done this job without this tool

I wanted something that would help me line up accurate holes this wasn't it

I needed this to make angled holes in my Carpenter Bee Traps. Lots of little pieces. I found it fidgety. Pieces can easily get lost. I can see my self over torquing that feeble Allen wrench stripping it or twisting it until it’s worthless. Then I’ll through the whole thing out when pieces come up missing.

The metal tubes that guide your drill bit are rusty on the inside

The media could not be loaded.  I was looking for a jig that could help me drill holes at an angle and came across this. Upon receiving the jig, initial feel was satisfaction at the solid feeling. There's 9 total holes starting from 25-45 at 2.5 deg increments and the final hole is on top for the 90 deg hole. With the jig, comes 8 bushings, 4 for angle and 4 for level and 10 allen screw locks to hold the bushings. The bushings shown in the picture show the size they're meant to guide. They are 3/16", 1/4", 5/16", and 3/8". The 3/16" bushing fits well. The problem I encountered is the other three sizes. The bushings are loose, too loose to be bushings. They're more like guides that point the drill bit in the general direction. I've attached a photo with my drill bits in the bushings to show you the jig with the corresponding drill bit they're to labeled to "guide". The sloppiness on the 3/8 is so bad that you have more than 2.5 deg of play at the angle of attack. You could be in the 30 deg slot and have anywhere between a 25-35 deg hole based on how you position your drill. That is not the level of precision I was wanting. If they tighten the guide bushings for the 1/4", 5/16", and 3/8", then this would be 5 stars. But as shipped with the clearances on the bushings, you have more than 2.5 degree play in a jig that is designed to give you 2.5 deg increment angled holes. That's not good.

The product had no way to securely fasten it to the post while in use and tis cause the drill bit to be able to get out of alignment with the designated exit point it had to much room for error the guide was not thick enough to keep the bit in place as it passed through this allowed the bit to change angles as it bored through the post cause it to come out the incorrect exit point

It starts off ok, but as you use it, the hole gets wider as the drill takes off material from the soft metal that the guide inserts are made from. This makes the guide worthless after a dozen or so drilled holes.I gave up on it and bought a big gator drill guide which works way better. I definitely would not recommend the Muzata guide.
