I cannot believe I have been eyeballing center when installing hinges. These are incredible and SUCH a time saver. High recommend you buy these! They will make your life so much easier. These are good and worth the price difference in my opinion.

If you've ever tried to center a hole, but been off by a little bit, these will end that frustration. These bits are definitely worth keeping on hand. Good value for all the sizes which you will eventually need.

Theyre excellent quality, and just work great. I'm still thrilled with my purchase. Definitely get this set. Worth every penny.. I used these already to install stop hinges on some keepsafe boxes. These don't cost much too, and work really well

Easy to use and very accurate. Select the correct size and let the drill tip seat in the hole. After seated in the hole, start drill and press down. I strongly recommend this product for those who need to get the hole perfectly center in an opening like a door hinge, etc..

As a carpenter/cabinetmaker I have used a lot of different self centering bits for hinges/hardware/etc. My first day using the smallest one from this set I realized they were better than any of the others I have used before. These are much smoother than any of the others and I like the fact that they are overall shorter length than most others too

Over the years, I've mounted a few hinges and have not always hit dead-center drilling the pilot hole. These, take out the guess work, misalignments and other negative factors. I wish I had had these 20 years ago.. Buy this item and you won't regret it.

This little set works very well to ensure you center the pilot hole for hinges and I have added this to my drill set. To date, I have only used the centering drills on oak doors.

These self centering bits work great. I have used them several times to install hinges on some woodworking projects. The place the hole dead center and function smoothly. Simple to use, perfect pilot holes and very good debris clean out.

I have been using these bits a lot for the past 2 weeks. They are sharp, have a smooth plunge, and seem to be able to take the strain from repeatedly drilling into hardwood for doors. Great buy.

Just what I need for professional results! Don't know why I waited so long to buy these. They make drilling perfectly centered screw holes for hinges a breeze. The different sizes are more than adequate for my needs.

Great tools, much better than the ones typically found in the home improvement stores. Well made, good springs, not cast but machined easy clean out and bit replacement. Use them almost daily

Guarantees a perfectly centered hole. No more marking where you think the center of the hole is, then hoping the bit doesn't drift and then the flange of the head of the screw moving your bracket because the hole is off. This bit forces the hole to be perfectly centered with no marking or measuring, every time. I love it.

Made the job much faster and for a cleaner install. Product is very high quality. Hinges and drawer pulls stayed in place allowing for an exact layout. I used with my impact drill and it worked well with this setup.

Invaluable tool in the shop. If you want the holes to always line up, these are what you need. Should have got these years ago.

So happy I purchased these, beforehand I was using a punch and drill and then still at times wasn't truly centered, this takes the guess work out of it and makes it easy to drill holes in the center.

I didn't know how many uses I would find for these until I got them. I used them for predrilling almost anything that has a mounting surface, door latch plate, metal shelf brace, hinge, etc.. This is an incredibly handy tool and I'm very glad I purchased it.

I use these pretty frequently and I really like having access to several different sizes. It sure has made things easier while lining up cabinet door hinges! Very sturdy!

A really useful item for your tool kit. Whether it's centering a hole or drilling out a deep stuck broken bolt, this is a tool that when you need it is indispensable.

These work great! For getting screw holes centered for hinges and things like that. The quality is great, great price.

There is a size in this set for just about any hinge or other object you need to drill a center whole in. I use these for drilling in wood to mount hinges, clasps, lid stays, etc. They are fairly sharp and work smoothly.

I have had four different sets of hinge drilling bits and these are by far the best set. The springs are well made and strong. Excellent set of drill guides. The tool accurately drills the guide holes when installing hinges.
