Soft metal
When tightening the chuck the key was deforming.

Decent but small
I ordered this for my bench top drill press. These are the only ones (sizes) that show up on Amazon, so for $5 I decided to give it a try. Shipping was quick and product was packaged as could be expected. It seems of good quality and appeared to be useful. Unfortunately, this tool is VERY small and didn't work for my drill press. I do think that adding standard chuck key measurements (pilot dimensions, gear diameter, etc) would be very helpful and clear up a lot of ordering confusion and returns/refunds. While I thought it was decent, due to it being small I didn't have a need for it and had to return it.

Nothing wrong with it, just didn't fit the right angle grinders at work..

Item is not as pictured
Item picture clearly shows “ST” imprint which likely means Stone Tools. Received item has no ST imprint or any other imprint that I can see. Deducted 2 stars. Steel used is relatively soft, (and non-magnetic). Paint worn off after first use. Fits 3/8 in chuck fine. Very low price. Suitable only for lightest duty applications.

handy
This does NOT fit a Rigid -Supreme 2A but it does fit many others.

Good little 4 way
I should have paid a bit more attention to the sizes and pilot sizes, so it won’t fit my 1/2 drill press. But it is a good little key, so I am going to hang on to it as a just in case 4 way key.

Good value
Just what I expected

The Quality and fit is Excellent
I have two drill presses and each drill press has their unique chuck tool. I also have several electric hand drills that have their own unique chuck tool. When I saw this 4 way chuck tool I was hoping that it would be a good back up in case I lose one of my chuck tools. After receiving it I tried it on all of my drills and to my surprise it worked on each one . I was impressed. It is very heavy for it's size which means it must be real steel and one would not expect the gears too strip easily. I highly recommend it as if you lose your chuck tool this guy will bail you out..

Use once and destroy
Teeth broke off first time I used it due to poor quality steel. Went out and bought genuine replacement part for my Makita hammer drill due to the original being lost. Vendor should remove 'Original Professional Master' from item name. Tools need to be reliable. This is one you should pass on.

This tool is the same cheap import chuck key
This tool is the same cheap import chuck key. The casting is cheap, the finish is a cheap paint. The key size does not match advertised sizes.
