Drill Guide
I am making a vibrating table to be used when casting plaster or concrete into molds. The drill guide allowed me to drill a 1/8th inch pilot hole through the combined 3 inches of wood materials that made up the table. After I had drilled pilot holes in each of the four corners I was able to accurately insert threaded rods and springs confident that they would be vertical and relatively parallel. Inaccuracies appeared during rod installation, but this was easily corrected with better bolt adjustment. I also used the drill guide to accurately drill holes for the vibrating motor mounts so that bolts could confidently be placed It is a great tool for this kind of occasional use! There wasn't much design tolerance. The 6MM screws had to fit into the 6MM mounting holes. It worked well.

Portable drill press
This is the closest you can get to a portable drill press. I drilled 450 holes across 5 sheets of ply. Straight and true. Excellent little tool.

Solid and did what I needed it to. I didn't need exact precision so this did good but wasn't perfect but that's not why I bought it.

Nice when you need it
Bought this on sale, and have wanted one for a long time. I have 2 drill presses but there is so many times you need to drill accurete holes on projects you just can't get on, or to a drill press. My dad used to have one like this and it was our drill press.

I found many tools for my cabinet making company but this tool I really needed because I have to be sure all my holes at exactly 90 degrees for mounting speakers.

Richard S on Jan 28, 2019
I needed to drill long holes in the width of a slab for hidden mounts for a live edge shelf. My drill press has not been moved to my new house so I need to have something that can help keep them centered and straight on my piece with a handheld drill.

This looks like a viable alternative for a "low budget" drill press. I'll let ya'll know how it works when I receive it.
Steven G on Nov 17, 2018
Starting a major project which requires multiple accurate holes for post and beam assembly. The guide should eliminate possible errors.
Gary S on Nov 16, 2018
Always wanted one. Good reviews. This one was on sale. Can put adhesive padding underneath to avoid marring the wood surface due to clamping pressure. I already have a drill press but this gives me greater flexibility for drilling vertical holes.

I need to drill holes in 6 x 6 posts for cable rail can i do that with this product?
gary h on May 17, 2016
BEST ANSWER: Not real clear on what you are trying to do. But if i understand it correctly, you are drilling a hole through the side of the 6x6 to pass a cable through. The post will be used to support the cable, like a fence post? If that is the case, then yes the product should work. You might be limited on the depth of your hole due to the length of th drill bit and what the press will accommodate. I have to drill through 8"-12" glueLam beams. I utlize the press to get my hole started straight. Then i switch to a longer bit in order to finish the hole all the way through. I would think that this press would get you through the 6x6 post. If not, then you will have probably less than inch to finish out the hole.
What is the maximum depth travel of this thing? In other words, what is the deepest it will drill without adjusting the bit? I seem to have a hard time finding these most basic of specifications on tool adverts these days.
Wil B on Aug 21, 2017
I need to drill 1" holes through 6" x 6" red cedar. My drill bit is 7" long. I have two questions. Will the torque for this project be too much for the drill guide? Can the drill guide accommodate a 7" bit?
Bob A on Jun 6, 2017
I have bought that same drill guide a couple years ago. My wife wanted a gin and tonic rail on our deck. I had 10 post 3 1/2" x 3 1/2" that I needed to drill 2 - 1" holes to feed in the 1" copper pipe through to make the top two rails. I made a jig out of 1/4" plywood with the two holes drilled at the right position then flipped over the post and drilled in from the back side. The holes lined up prefect to give me a clean hole all the way through.
With the right drill bit and drilling through both sides it should work fine. You need 3" deep hole from each side to make it work. You will not made a 6" deep hole drilling through from one side you will have to flipping the post drilling from both sides.
I need to auger 1/2" to 7" deep from the bottom of a 4' 4x4 cedar post so I can insert a threaded rod. My bit is 17" long. Can this be mounted on the bottom of a 4x4?
Chad M on May 30, 2017
BEST ANSWER: I think your bit will be too long for the drill guide and the drill guide cannot tolerate a lot of torque. Take the board to someone who has a drill press.

need to drill holes into small glass panels.. Need a very sturdy drill press for portablel drill Will trhis do the job and not wiggle to split the galss?
A shopper on Jul 13, 2015
BEST ANSWER: Not a very stable item. Fair for drilling basic holes in wood and metal, but not something I would attempt to use in "small glass panels". I feel it would be awkward and not stable enough. I purchased to use in the interim till I find a drill press and used only once to drill some small holes for a small project. I had to wrestle with it to make it work for that. Just too much play in it overall to use with any precision. I would give it about 3 stars out of 5.
Made from metal?
Ted L on Oct 1, 2016
BEST ANSWER: Metal frame construction. Sturdy, stable, and easy to use.
Does this device have a depth stop so I can drill a hole 1/2" deep into a piece of wood? I need to drill a number of 1/2" holes 1/2" deep in a coffee table
Rubiconlwb on Mar 1, 2016
BEST ANSWER: Yes. On the bottom right (in the picture ) is a knob that can be tightened to the bar. After you raise it to the desired height and the spring compresses to that point.
Project: To drill a 6" deep 3/4" diameter hole in the center of an 18" tall log. The logs are 3 to 8 inches in diameter. can this tool help ?
markd on Feb 15, 2016
BEST ANSWER: A 3 inch log wouldn't work. That's smaller than the opening in the base.
I need to drill 1/2" holes in the base of a stair rail so I can install wrought iron balusters. The top rail is fine and has 1/2" holes already, but on the base where the stairs angle up the builder had nailed in the wood balusters, so there are no holes in the base where I removed the wood balusters. Can this drill guide attach to the base were the bottom the the baluster needs to fit so I can drill a straight and not an angled hole?
Omega on Aug 5, 2018
BEST ANSWER: This is not the most stable tool however it did get me thru my project. if the base is 100% supported and you work carefully you can make this work.
is the adjustment of the guide angle infinite or limited to 5 degree adjustments?
William G on May 11, 2018
BEST ANSWER: The little detents are every five degrees so these are easy. Between detents, it all depends on how tight you can turn the side setting screws. If you do this, use a sharp bit and a light pressure on the drill. This will reduce the torque transferred to the jig

Can I use a mortise chisel bit ?
Osvaldo H on Jan 20, 2018

Guest on Nov 25, 2017
The project is pillar bedding a gunstock. I want to increase the size of an existing 1/4" hole to 1/2". The bit must follow the 1/4 inch hole exactly. The 1/4 inch hole is about 3 inches deep and at a slight angle in the stock. Can I do this with this drill guide?
James C on Apr 6, 2017
BEST ANSWER: No you will have a hard time trying to clamp it
What is the largest diameter bit (forstner) that this will accommodate? Will a 1.5" or a 2" fit through the hole in the base?
Shane F on Jan 13, 2017
BEST ANSWER: I do not know if the bit will fit or not, but my advice to you is to not purchase the devise. Even if the bit will fit the torque required to drill the hole will overpower the devise. The unit is too weak to provide any accurate support. I purchased it to drill 3/4" holes in a carpenters bench and after using it once wished I had not. You will be miles ahead by just building a gig for the need and you will still have the money in your pocket.
