Rocaris 9 Pack of M2 M2.5 M3 M4 M5 M6 M8 M10 M12 Titanium Coated HSS Spiral Flute Metric Taps Set

Work very well . Good price

I very rarely write reviews. I am a very heavy Amazon user. I spend ten's of thousands annually with Amazon both personally and for my company. First of all I wasted so much time going to local hardware stores to find a metric tap set. The local Ace Hardware store showed them in stock, but after a 20 minute ride to the store, they were out of stock. What an amazing waste of time. I tried other local stores. Another waste of time. Can never recover from loss time. I went to my tried and true option. AMAZON. I found this tap set, which was delivered the next day. It retapped a stripped hole as smooth as silk. The true test was that my metric bolt easily threaded into the tapped hole. I love this design of this tap set because it removes material as it threads in. No need to clean the threaded hole afterwards. I LOVE YOU AMAZON. Have been a user from the start, primarily for buying books. Even Dostoyevsky and Hemingway would love you, if they were still alive.

These taps are great. I gave it a 4 star because all the taps were just placed in a plastic sleeve and were rubbing and banging around against each other.

These taps worked great in tough situation. I had to drill out stainless steel bolts that were in an aluminum housing and these worked great.

i used the 3mm tape after i broke a standard tape. The 3mm tape cut great by hand and in the 2hp knee mill

Works great, having a set of taps is a great addition to anyone's toolbox, if they break, they weren't that expensive.

Works well in aluminum extrusion and plastics both with manual drives and with power tools. As others have noted, they are shipping in a plastic baggy which isn't much protection from each other or external damage.

This company is selling itself short with stuff like a plastic bag and not proper 5 cent plastic holders. I have plenty of std taps, they work well. Have been eye-balling a set of these spiral flute taps for awhile. I really like the idea of the material coming out the top of the taps flutes instead of getting eaten over and over again by being stuck in the way of the tap. Mine were shipped in a zip lock bag too. No noticeable damage. I have drilled and tapped 3mm, 4mm, 5mm. All I can say is wow, so much different than std taps. As I said, this is my 1st set of spiral flute taps, and its a cheap set to boot. Will a name brand be alot better? I will buy a single tap and find out, but for now, I am pleased (except for the stupid baggie thing). Snapped a few pics of these in action etc. edit* If your taps are sticky, simply wash them in gas or any degreaser and sticky gone.*

Good quality. Exactly what I needed

Hardened cutting edges worked as it was supposed to making threads into aluminum.

M5 broke after second hole. Used very little torque when tapping the hole.
