uxcell 5 Pairs Metric Hand Threading Tap Set M3 Thread 0.5mm Pitch Taper & Plug Milling Taps Straight Flutes High Speed Steel

I needed these to tap holes in the end of aluminum t-slot extrusions. So far I have tapped 30 holes all with the same tap and it shows no signs of wear or chip weld.These taps are fully ground! Not like cheap taps that are machined while soft and then hardened. Those types of taps can work ok, but taps cut better and are more precise if they are ground after hardening.

These are seemingly high quality, and tap aluminum pretty well. These are great to keep around with a 3D printer and assortment of screws.

They worked well for the brass that I bought them for. Although, the threads were quite a bit loose, so I will have to use some sort of thread sealer or glue to prevent them from buzzing or rattling loose. I have only used one of them to thread about 8 holes in 1/4" brass, so I cannot comment on the consistency or longevity of the taps. But, they were inexpensive and came with 10 in the pack so I'm not too concerned. They mostly fit my needs...mostly.

They worked for my needs

The first one I used didn't create large enough threads to accept a machine screw. The second one I tried opened the threads up a bit more and the screw was able to go in. Seems like the dimensions aren't all that consistent, but there are some good taps in the batch I got.

they broke in a minute they are made of chinese crapthis sellers are amazon friends allow this crap to be sold to =customersthis is how amazon makes money stealing from customers

These are M3 taps that came in a pack of 10. The picture tells the story; compare the grind on the tips. The left tap is a reamer, particularly when used on thin material, whereas the right tap actually works. Five of the pack were reamers, so double the unit cost when you purchase these!

Insanely dull, completely unusable.

These taps are reasonably priced and work great for the job. I have used them on two different metals so far and each time without issue. They appear to be good and sharp and cut easily. Being m3 they are fragile and would be easily broken if used without care.

Worked well to cut threads in a brass gear on a clock.Includes 5 pairs of tapered taps and finishing taps. These are 2mm the full length so needs a tap wrench that will close to less than 2mm. I work gently to prevent breakage but taps seems to cut well and did not show any sign of stress. No issues when using these to extract a brass gear on a grandfather clock.These should stand up to multiple use, particularly considering there are 5 pairs!

The taps work quite well but being very hard metal are quite brittle. Do not try to use these with a power drill or single sided wrench. Used with a proper tap & die wrench I was successful. I broke one and had to drill it out with carbon drill bits.

Perfect set of M3 taps, these appear to be exactly what one would expect.Uncoated HSS, delivered in a neat little sorting tray and shipped in a LIGHT oil film.I've only used one so far for a handful of tapped holes, and so far it looks to be holding up perfectly; unlike the big-box-store coated tap I was using!

Bon rapport qualité/prix. J'utilise ses taraud avec une tete a tarauder automatique (Tapmatic) et le travail est excellent! Je recommande
