Good stable drilling platform
Have a very small shop with no room for a drill press. This guide serves the need for stable drilling guide. I am sure than an expert might immediately know why the base as slots and groves but less obvious to me. Also looks like it could be clamped for more stability but not discussed in manual. Be nice to have more guidance concerning its use.

Very pleased
Saw my contractor using this device. I admired it’s ability to force me to drill straight/perpendicular holes. I purchased it from Rockler and couldn’t be more pleased. Works as I hoped. Works as they promised. Good design and construction.

I had one of these in the past and was very satisfied with it. This one here looks more versatile. The one I previously owned did not have the ability to drill at an angle.
bob d on Dec 22, 2019
had one years ago, lent it out, lost it. I like that this has a Jacob's chuck attached. The old one I had to take the chuck off the drill and screw the device onto the drill. Major dolor de glúteos!

Matthias Z on Nov 1, 2019
I choose the portable drill guide due the light weight capacity and overall versatility for when a drill press just isn’t readily available or causes restraints. Besides you can never have enough tools to make ‘work easier and not harder’....

on a 90 deg. drill position, what is the longest bit that I can use?
gdew65 g on Oct 20, 2016
BEST ANSWER: I used a 6" long bit successfully and had some room to spare
I am going to drill hardwood flooring to put plugs in for looks only. will this work for that?
Bob N on Jan 14, 2017
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
What is the largest diameter hole saw that can be used to cut a hole at a 45º angle, please?
Stephen L on May 11, 2017
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.
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.
Will it drill holes at 37 degrees angles?
Carole M on Jun 3, 2019
BEST ANSWER: I returned this item as it was not a quality and accurate tool.

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.
can a flat bottom bit be used?
david n on Sep 15, 2016
BEST ANSWER: Yes. I actually used this to drill mortises with Forstner bits when I built my gate.
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
Lee B 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.
Can this be used with a Dremel?
Peter R on Jan 30, 2020
BEST ANSWER: I don’t think so. Don’t think the dremel chuck is big enough to accept the guide chuck. I could be wrong though....if sizes work then...maybe.
Will it work to drill for spindles in a stair rail?
Gerry D on Dec 22, 2019
BEST ANSWER: It will, yes, but....I would look for another method. Make your own jig. Rockler sells many other drill guides, blocks that could be clamped to your work to produce better results. Good luck!
is the driver for the chuck 3 sided or round?
ghost on Dec 22, 2019
BEST ANSWER: The one I have (bought 12/2017) is round.
Does it give you the option to get a larger chuck for drill bits above 3/8 shank ?
Dennis O on Nov 10, 2019
BEST ANSWER: No. In fact, the chuck is the week element of this product. The chuck quality is lower than expected.
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
BEST ANSWER: No, there is no attachment to hold the mortising chisel.
Besides the handle what holds the unit in place? Grippy bottom? Seems like it would really start to “walk” drilling into harder woods especially at a steep angle. Has this been a problem for anyone?
Tristan W on Nov 15, 2019
BEST ANSWER: Tristan, you are going to have to use a clamp or 2 to hold this unit into place to get quality
results. Make certain the drill bit hits the spot you have marked first, since you may have to make adjustments.
Slowly apply pressure as you are drilling, since there can be a slight wobble where the connection of the drill bit bar is attached to the spring guide rods.
I bought another mfg guide of similar geometry. Was made of plastic. Total crap material selection. What is material of cross guide and base plate? Hopefully metal!
Paul K on Oct 14, 2019
BEST ANSWER: Yes it is metal, Paul, I've been using the drill guide for a couple years now and have had no problems. The first project was helping my daughter make a 9.5 ft cribbage board, with almost two hundred 3/4 inch holes. Still works as good as when I bought it.
Mike Skauge
will it accept a 1/2 chuck drill as well as the 3/8 chuck ?
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.
