RUKOTerrax Hand Held Tap Set DIN 352 Ground M6

Unlike some other reviewers of these taps, I have found them to work very well indeed. As an example, I attempted to tap a hole, in a cast iron vice body, using a cheap set of carbon-steel taps. It was very hard going and one of them broke-off in the work-piece. Luckily, I was able to remove it from the hole. Subsequently, I tried the Ruko Terrax set. These three taps worked like a hot knife through butter. The process required much less effort and produced a clean thread. None of the taps broke. I'm certainly no expert in the use of taps and dies. Nevertheless, I used this HSS set with ease. Based on this experience, I recommend them.

Bought these hoping they would last better than the generic taps from b&q but no, unfortunately not. It would seem I got a defective finishing tap which snapped a flute with basically no force at all, not what I was expecting for the price. Going to be trying another brand for sure. EDIT: Exchanged for Volkel taps of the same size and they are far superior, they cut a lot easier and seem to be designed so it won't sheer inside the hole. Definitely spend the extra few pounds.

They are much better than the el-cheapo set (single cutters) that I've struggled with for the last 15 years, but they are also not bottom taps as shown. All are tapered to a point. I ordered them because I need bottom taps....That said, I've used them 4 times since I've had them and they make a nice thread once finished.I bought M4x0.7

needed a tap for a blind hole and believed that looking at the photo this is what i would getunfortunately i received a set of standard taps so my search goes oncan't be bothered to send them back got better things to do

The price was right as I thought I'd try them and was really surprised by the quality of the steel used...very sharp and so far streets above similar priced taps.Worth trying

As other reviewer, I work in stainless steel, and as he described these taps have not been made correctly, I threw the taper tap away as it was useless! The second and bottom struggle aswell. Perhaps this was a batch manufacturing error, but I wouldn't recommend buying these, even though Terrax are normally good.

Good quality taps. Work well with good progression of cutting stages 1,2,3 leaving good finish. Was able to tap a hard piece of stainless steel.

Excellent product. I needed to tap 38 holes, half done with a 1 piece tap of witch i snapped 1. These Zipped through 9mm of steel in less than half the time it took to do the first 19 holes even with needing to swap out the taps.
