Value for money. Works good and easy
Great bits, exactly what I needed and a great value for the money for sure.
Very nice set. I broke my M4 after tapping about 100 holes and it was because of my own mistake. Taps are sharp, I used on aluminum -very good cut.
A tool that we all need
This is an excellent product, and does exactly what it is supposed to do if you have knowledge of using tapping bits. Have used these several times so far and have worked perfectly. Obviously you will need to be more careful when tapping wood as it is softer and if you don't take your time backing out the bit then you will mess up your tap. Again, if you have the know how on using tapping bits, these are EXCELLENT :)
Great little tool to have when breaking crews👀. Drills right through and re threads with ease.
the bits do drill and create the threads as advertised.
I bought these to tap my wood carvings to use as bottle stoppers, It worked out well and the tap was just right for the bottle stopper
Did not break worked on many hole/threads
This is just what I've been looking for but I had to get use to backing out of the hole without messing up the threading.
A Plus Product works great and easy to use. Price was right. With a strong fast cutting edge. Will buy from seller again.
Used this to chase threads on body panels before re install
This threading bits are amazing. They do the job as advertised.
Such a time saver. The most popular sizes someone uses all the time. Great all in one device
I like the hex shank on these. Seem well made. Durable ? Time will tell.
They're stubby compared to a full tap but worked great for what I needed on a motorcycle frame. Drilled and tapped 1/4" steel and 1/2" aluminum parts so far with the 6mm and 8mm. Center punch was handy and even came with a little case. They might work on thin stainless even. Great for what it is.
Really speeds up the home made metal work in my electronics lab. Fast and forgiving
I had some name Brand, just like these.but snapped one. I bought these for backup in case...glad I did.. I had to use one of these to drill and tap alot of holes for my plasma table.. it worked Great.. But I do predrill with another bit..
They will cut threads as long as you machine or drill the correct sized hole to start with. they will not drill the hole AND make the thread in one action. They will cut the threads no problem using a proper application of cutting oil and to reiterate, the proper hole is already drilled/machined in. I used these to add a DRO to a mini mill as well as install a 16" bed onto my 10" mini lathe, these projects utilized just about every sized tap. None failed and all cut good threads with minimal starting effort.
A good add to the toolbox.
Working perfectly for my project
These are great easy to use and surprising
I use this product when cast iron flange bolts break off. I tap a larger size in and these work perfect.
I like everything about that drill bit set
Love the durability
I get irritated with seller wanting reviews but this item is a mechanic best friend. I work on motorcycle and this has save me an hour on my last job.
High quality. Works as advertised
Easy to use no problems
Everything good about it
I had to tap out new bolts and I love those bits
Received as listed very happy
Always love having these around. saves a lot of time and easy to use, last a long time. Be careful not to use impacts.
Bought the set because I was needing the M10x1.5 tap. It worked well on aluminum.
They work good
Punch sets deep for easy drilling. Bits are sharp and easy to use.
It did what is was intended to do.
