Use a drill press with this jig.

Don't use a hand drill with this jig.  Works great if you have a drill press to insure the axel holes and perpendicular to the car.  Using a hand drill results in the bit wondering off of course.

I purchased this jig to install shelves in some existing built-in cabinets but this jig really is probably best used on free-standing furniture. Your circumstances may allow you to do so but didn't work for me.  However this is a great little jig if used for its intended purpose.  I also have the Kreg Pocket Hole jig which is an amazing jig as well.

This jig is simple to use and well made.  I had wanted the jig from Rockler but theirs is made from some sort of hard plastic and the drill guides aren't made with hardened still like the Kreg's.  The Kreg jig's fence snaps on easily, and depending on which side you snap it on, determines the distance from the edge of your wood.  The jig has to be clamped into position if your wood already has a face otherwise the fence can be held in place while you drill the holes. There's a video that demonstrates its use at Kreg jig forum.  I posted link but Amazon removed it.

Vertical alignment is easy using a locator pin to connect the jig to the last hole you made, or you can buy more than one jig attaching them together to make a longer jig.

Comes with everything you need, including 4 shelf pins.  Storage for the locating pin, the drill bit and depth collar is located on the back of the jig.  Instructions are clear.  Highly recommended!

Get this if you are getting the Kreg pocket jig.  Use it first to clamp the jig to the wood piece you are drilling, then second be sure to use it to keep the two surfaces you are joining flush.  The peice you are joining has a tendency to rise about 1/32 of an inch if not clamped well.  This works great for that.

My porter cable drill press always had problems with excessive drill bit runout.  It turns out the problem was a poor quality chuck that came with the drill press.  Once I put this chuck on, the drill bit runout is essentially zero.  I would buy again.

A simple jig that will make cutting large panels a much easier task.  I am going to Haiti on a mission trip and have in the past had to use the board and clap method to rip large panels.

I use the drill press and get busy and miss place the chuck key, because it has a holder but it is not easy to use. With the magnetic holder I just stick it to the front of the top housing and I always know where to find it.

This product worked exactly as advertised. I used a homede wooden jig bolted to the block surface to ensure that I drilled and tapped a perpendicular hole. It salvaged my rebuild project.

The jig works very well. It is necessary to check it before each cut because of slight variances in wood. It had gobs of grease on it, which was a pain in the drain to clean off, but also necessary since it is made from ferrous metal that would otherwise rust. It is easy to use and (thankfully) to tweak when needed. I would recommend it to someone experienced in working with jigs. I would not recommend to a novice or an impatient woodworker.

Upon receipt of this item I got busy and sharpened the many dull bits in my tool chest. Once you get the hang of it, this sharpener quickly revives bits that would otherwise be tossed. First, loosely insert the bit in the chuck and put into the aligning hole. Once aligned, tighten check and insert in sharpening port rotating slowly several turns. After initial sharpening you can split the point if desired. Just follow the directions or refer to the videos on the Drill Doctor site.

Ordered this for 1/4-20 furniture levelers.  As others have suggested, I drilled a 1/32" oversized hole (in end grain ash).  I lubricated the holes with a thinned out waxy product (but any lube would do).  I used the jam nut method on a tool that I repurposed for the task.  I was able to rap the end of the tool as one might a nail set to get the insert started reasonably straight and then just carefully applied pressure as I twisted the insert into the hole.  I ended up countersinking the insert a bit and when I backed the tool out, it came away nicely.  Even though I had an issue getting the first insert straight into the hole, by using the nail set method I was able to re-drive it in straight.  The other three went in with no issues at all.  Pleased with the product.  It worked out well.

Works well for woodworking jigs.  It's a little thick.  You will need good scissors or a knife to cut it.

As others have noted, the tool steel "bits" are not shaped for use.  You will need to grind them to shape. If you don't you're going to have a lousy finish and make a lot of noise trying to surface anything.  The set screws are made of a very soft steel - so soft it is easy to round them - if they aren't loosening, don't apply massive force; just "spring load" the allen wrench and tap the back of the wrench at the elbow with a light hammer.

Works great, this type of but likes to walk around the work if your not using a guide, so make sure you have a firm grip on the tool. also, while it can do a decent job on 1/2 inch plywood, i wouldn't use it one more than 1/4. the bits heat up too much and shatter. on foam, as long as the bit pokes out a bit, have fun.

This is not an easy installation. Basic hand tools will not do the job. The power tools I used were "250lb. impact wrench, 4in. angle grinder bench top drill press." Start to finish took about 4 hours.

You need DeWalt drill bit set to use it with this holesaw.  Standart drill bit set will not fit.  If you buy it, be sure you have the accesories to use it, or buy them too.

These work well in my new drill press.  I've only tried them in wood so far, but drill a smooth, straight hole.  they run true  - not too aggressive that would tear softer wood.

You will get a nice job of planing. look to be a very dependable tool for the money .
It is being used in a commercial wood shop.
