Very well made and really good price compare to local stores.

I just installed 50 cabinet hinges and these self-centering made the job s lot easier.

They work just as described and allow a centered hole when placing hinges.

Works exactly as described; makes short work of centering pilot holes for hinge screws.

These work as advertised, should have bought a set years ago

The nice thing about these over my originals that got lost over time, is the hex shank

The nice thing about this is that the tip is curved so that even if the tip is larger than the hole of whatever you're trying to mount, it automatically centers itself

Good value for three sizes which you will eventually need.

The price was a good value compared to the 'name brand' for this type of bit, although I can't comment if the functionality is the fully the same; for example, I haven't tried to adjust the depth.

I'm happy with the purchase and can't think of a better design,

This seems like a good design, but the quality is quite poor

These are very handy to have, I am a carpenter and use them all the time, very worthwhile tool to have

The perfect tool for installing hinges or other hardware and getting the screw hole perfectly centered.

Cheap tools work fine for some things, but for this type of tool, spend a little more

If you do quality work, you know there are certain jobs you can't do without the right tool.

This is an incredibly handy tool and I'm very glad I purchased it.

I feel this product is fake

The spring tension is just right IMO, the product is machined well, and the bits are sharp (and can be replaced if one breaks).Self-centering bits are a must-have when drilling for hinges, brackets, drawer slides, and similar

I had my doubts when buying it, but it exceeded my expectations, clean and centered holes, excellent product quality

Very good product for centering screw starting home in hinges

I like Bosch products, and this one does not disappoint.

FYI: bits break

These bits have none of those drawbacks, and I highly recommend them

These seemed like nice bits and I have never had any problems with a Bosch product until this one

These bits are a bit expensive...but worth every penny!

If you install hinges, these bits are worth every penny

I used these a few times, almost exclusively on soft woods, and all but the largest have broke.

And you don't need to be a furniture builder to benefit from a tool like this - the first time you use one for a bracket or hinge, you'll wonder why you didn't buy a set years ago.

you need this bits you always search the other ones you need in your tool box for enough time to get mad

This seems like a good design, but the quality is quite poor

Overall this product is very well made and of good quality.

Good quality although they could be polished a litter little more to make them smoother

The bit itself is good quality and stays sharp (I only drill wood).

Not only do they save you time, they improve your accuracy and quality of your workmanship

Once centered in the hole, pushing the drill into the wood to make the hole was very smooth with no catches

No problem, just drill the shallow hole and chuck up a long drill to finish the depth.

Worked great drilled holes for a continuous hinge and every hole was centered.

Three sizes cover most hinges - they work great for other things that require precise hole placement.

But, they still make nice clean holes, reasonably centered on the hinge holes.

hopefully a upgrade from a cheap set purchased from a box store

Love it.. is there a countersink set available from this manufacturer?

This little set works very well to ensure you center the pilot hole for

Bought a cheap set before and was a complete waste of $

I have been using a cheap set of center bits for a year now
