I'm a DIY'er and I have had to use these a couple of times now. They work great and I am pleasantly surprised at the quality. Don't know if a pro would like them as I don't know what the expensive ones are like but these definitely work for me.

I put a light coating of machine oil on these and worked them back and forth a few times to remove the slight manufacturing burrs on the inside. I used one of the sets to drill some center holes for a hinge and they worked just as I expected. Good range of sizes for the price.

The Self Centering Drill Bit Set performed well In several sizes of countersink tap drilling. I used 3 of the sizes over several days and had consistent results. The bit is centered by the nose when placed in a countersink such as a hinge. I found the case serviceable. These are a good value. Thanks

Perfect tools for light duty use around the house. I needed a center drill bit to replace all the kitchen cabinet doors and, so far, this set has worked very well. They certainly stand behind their products and I won't hesitate to make another purchase with them in the future.

Always wanted one of these sets. This comes in really handy when trying to get hinges put on and get the screws in the right spot. Nice tool in my arsenal.

It seems like many companies are selling this product under a different name, the design and product build looks similar. I'm used to my Drill Bits Self-Centering, the spring-loaded plunger had a bevel on the end, easy enough to do that with these on your grinder or sander, I've done that to the small one of these already. But overall a good value.

I used these Self-centering Drill Bits on commercial wood doors. Snappy’s worked great and spread up the hinging process. A great addition to anyone’s tool collection

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

I am a boat builder and am constantly installing all manner of hardware and hinges. Cheaper versions caused more problems than they solved. These are EXCELLENT for the money. Well-made and accurate with little slop in the guide sleeves. The larger sizes are not always easy to find and very helpful.

Accurate hinge installation required accurate centering of the pilot holes. This set facilitates centering these pilot holes relative to the holes in the hinge plates. A well-made tool.
