Helps center my drill bits

Does the job though it is a cheap model. Very good for steel when trying to start a drill hole. Excellent for wood as it goes deeper. I bought Two of these within weeks of each other.  2nd model slightly more expensive (different manuf.) it has a slight harder spring and a nice big red soft end so it doesn't hurt your hand when using.  I recommend some kind of padding to soften the blow on your hands with this one.

these fit my dremel perfectly and enable me to use small drill bits.

Better than not having anything at all to hold your drill bit... but I have scratched myself a few times going up and down a ladder (with the drill clipped to my belt at my hip). It sticks out from the body of the drill a tiny bit too far... but it is built well. It holds bits of many different types, shapes, sizes & lengths... without worry of it coming loose.

I bought these specifically for building IKEA furniture.  I built a whole pile of things for a new apartment, and I encountered 3 different allen key sizes, and all 3 were covered by this set.  Almost everything was the middle size (4mm?), with a handful of screws taking the next size up or the next size down.

I don't know if they are super heavy duty or anything, but they fit the standard hex bit holder on my DeWalt drill, and I didn't manage to break any of the bits I used.  Being able to use my drill with the adjustable torque setting and a bit holder with a drive guide (extendable metal tube that holds the screw straight) made the process so much easier, and I didn't strip a single hole.

I have used this to hold drill bits, that are not made for a power driver. It works well, and the price was right.

A great little addition to my tool box. Actually I never put it in my tool box it stays in my drill. A very convenient time saver.

Nice tool, but a centering bit would have been nice.  The tool wobbled a little untill it seated its self.

I have a small 7" x 12" metal lathe. I wanted this unit so I did not have to keep chucking up a center drill, drill and countersink, when I had a dozen parts to make. It is a very handy accessory to have for your lathe

It works.  The bits do not slide out.  I wish it was shorter.  I am going to get another one.

The bit worked well enough on the pecan slab I bought it for. I drilled 5 holes about 3/8 deep. The size of the bit really lends itself to use with a drill press but if you use it with a handheld drill be aware that it may grab. It might result in the work piece turning or the drill torquing your hand/wrist.

The bit comes with a wooden storage box. It has 2 vertical braces to hold the bit. These are held in place with glue. In my box one of these had broken loose. I am unsure whether I will store the bit in the box but its large size means it doesnt fit in the storage bin I use for my other bits.

I like this bit holder and would recommend it. My only complaint is the pressure ball on the side doesn't hold the tips in tight enough and the bits fall out of the holder sometimes. I was using a 6 in one screwdriver shank on my drill before I bought this

The tool has a threaded locking function to hold the bits in place while working and the bit storage prevents accidental dropping. I do wish there was a little more fold or external pouch storage for lose bits included.

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.

I ordered this drill bit along with mandrel and trim kit.  I thout it wouldbea good idea to have two drill bits.  It's a good thing because the 7mm drill bit has a slight wobble.  I removed it and chucked it again....no change.  I took the 7mm drill from my pen kit and it turned true.  I'm sure the quality of this seller is good....I just got a bad one.

Really makes grabbing the proper but easier than searching for tips.  As an electrician I am constantly switching from Phillips to square to Torx back and forth all day.  I made a 5"  deep keeper with long bits sticking up for easy identification and inventory in my Tool Bucket.  Work Smarter not harder!

This is a perfect companion to a set of heavy-duty Forstner bits... a necessary accessory for drilling long holes in, for example, lathe turning projects such as pepper grinders.  It fits the hex-shank of bits from, e.g., Lee Valley, and is very well made... the bits run true and smooth when used in conjunction with the extender.
