I ordered the following item from Amazon on June 6th, 2019 and received them June 8th. Werkzeug Self Centering Hinge Tapper Core Drill Bit Set for Woodworking, Adjustable Door Window Drill Bits with 1 Hex Key & 8 Replacement Drill Bits (5/64 - 1/4"), 16 PiecesLooking them over they appeared to be well manufactured and of good quality.

This is not something I use every day but when I need a hole properly placed this is what I use. Two days later it was time to give them a try. When I removed the 5/64 bit the drill bit fell out.

I put it back in and took the Allen Wrench they supplied and went to tighten the set screw. The set screw would not budge and in fact twisted the Allen Wrench. I sent an email to the customer service department of Werkzeug which the address was found in a Thank You card enclosed with their product.

I'm not sure what the other guys did wrong or if they had a bad bit. But for my experience these bits are fantastic. I had to install these combination Assist Bar/ Towel racks in two tiled showers of some elderly customers, and due to the length of the grab bars and how the showers are there's no way to center them and hit studs.

It just doesn't line up. So I had to use the heavy HEAVY DUTY wall anchors that come with. We're talking the kind that can hold 70lbs each. These require you to drill 3/4" holes in the freaking tiles. As you can imagine with these being brand new remodeled showers just tiled, I was a little worried about doing this well and not cracking a ton of tiles.

These assist bars needed 4 holes each. So all I did was I used the smallest bit in this kit to drill pilot holes, which they did perfectly. I drilled nice and slow with my dewalt 20v max drill, pecking away at the hole making sure to clear out the ground up tile from the hole and to not let the bit get too hot.

I bought these to drill holes in the heads of some porcelain Santas I want to hang on my Christmas tree. I tried every kind of drill bit in the house, then I ordered these. They ALMOST got a ZERO star rating, until I figured it out.

On the first try, I put the 1mm bit on a drill and started drilling...Or trying to. It didn't even make a dent in old Santa's head.Boo! Then my husband tried the 3mm. No luckThen, my husband tried the 3mm under running water (as I found online that you should drill porcelain submerged).Success...

But the hole was ridiculously big. Finally, I had supreme success using the 1mm on a Dremmel (the drill simply wasn't spinning fast enough) with the Santa standing up in a coffee cup submerged in water so that the drilling site had just enough water over it to cover.

I bought these bits to drill holes in 1/8" stained glass. I had a really hard time learning how to use them without the diamond coating burning off or tips breaking. I originally left a negative review and hopefully it wasn't up long enough to do any harm.

I believe I have finally learned to use them through a lot of trial and even more error. No matter what method you use, always keep in mind that these are really thin delicate bits and they don't put up with much abuse.

When using these bits with the Dremel and drill press I had horrible luck. Most of the instructions I've read say to drill glass at really slow rpms and hold the drill completely straight (thus the drill press). I finally settled on drilling on high speed, holding the Dremel in hand rather than using a drill press, and building a dam of water with plumbers putty.

Door hinge installation is now easier than ever. These bits keep all holes drilled in a hinge, like a door ,directly centered so all screws seat flush and the door is not obstructed by screw heads. Also allows for hinge to seat perfectly in a recessed location for a perfect air tight fit!

NO MORE walking hinge when you apply 2nd, 3rd or 4th screws to hinge. NO MORE slowly screwing each screw little by little to get perfect fit ! Just hold hinge in place, screw appropriate size holes for hinge through the hinge itself, and then apply screws to mount hinge.

You tube hinge drill bits and you will see how fast and easy hanging hinges can be. The cone shaped tip on the spring loaded sleeve around drill bit alignes the drill bit in the cone shaped holes on the hinge to seat the drill bit perfectly centered in each hole and keeps you from drilling sideways by forcing drill bit straight in.

Wasn't sure how well this was going to work but was pleasantly surprised with results. I bought two of these SHDiamtool core drills, a 50mm and a 32mm for custom work on sandstone blocks 2 to 2-1/4" thick. I had 12 blocks that needed one 2" hole drilled completely thru and four 1-1/4" holes drilled an inch deep, not all the way thru.

These drills do not come with a pilot drill, so I made a template out of plywood and 2x4s with the same hole sizes and layout as I needed for the blocks. That made it easy to be sure the drill didn't skip or wander when making initial contact with surface of stone.

I used a drill press with water coolant and checked a core drill speed chart to make sure I was in the ball park for spindle speed - used 1080 rpm for both sizes - and these things cut thru sandstone really well and quite quickly using only moderate downfeed pressure.

It's an adapter that doesn't have the impact specification. Some of the people reviewing this product are asking for the product to do more than it was intended and then gave it 1 star when there is absolutely nothing wrong with this product.

I used this for some polishing pads that needed a variable speed angle polisher but I didn't have such tool. I easily put this product onto a hand drill and put the polishing pad on it and voila, it worked like a charm.

The ergonomics weren't as great, but that's not the fault of the product, but a fault of my budget for the project. A+++ rating for sure.

I needed this to get through a knife blade I'd already hardened and tempered (to about Rockwell 60) and forgot to drill *beforehand*. It actually got through nicely - although I'd caution anyone trying to do the same thing to use a cutting oil (preferably a REALLY good one, if possible one of the sulfur ones).Great results.

I bought this to repoint my masonry fireplace. Was worried on how to remove the cement head joints since there aren't as many solutions in the US as in England. I came across this solution that threaded on to my standard angle grinder.Glad I did.

It tackled both sides of the firebox and most of hearth with one piece. Just make sure to take it slow and if you have any soft bricks, to really hold on to the grinder as it will want to follow the path of least resistance.

Only downside is that I wish it could go deeper in one pass. Meaning, I wish the diamond tip part was longer so I could rake out more in one pass. But you just take two passes. And make sure to have the wife hold the shop vac near the brick and your dust problem will be gone.

A had to grind heavy pitting of my cast iron skillet but didn't have an angle grinder.This was perfect. I was able to buy grinding wheels and cutting discs from hardware store and attach them to this adapter, to my drill.

I bogged down pretty hard against the skillet with my drill, and this adapter performed beautifully. Good for anything that needs a 5/8 hole and 11-male thread.
