7Pcs Nitride Spiral Screw Thread Taps, HSS 6542 Metric Machine Spiral Point Flute Tap Thread Tapping Tool M3 M4 M5 M6 M8 M10 M12 for Metal Wood Drill Bit

Great bit of kit

Packaging is a little bit disappointing, well I say disappointing when I mean nonexistent. I know ots not massively expensive but I did expect some sort of way to keep them from being damaged rather than having to buy a small bit box just for these

Great item and service. I used these for some repais i was doing for a neighbour on a trolley of hers i was tapping into stainless steel and these nitrided taps did a first class job which my old taps struggled to do at all.!!Many thanksPaulD

I needed to drill 3 x M.3 sized holes through power coated stainless steel. I used an everyday drill and achieved this without any issue. The drill bit never snapped nor did I experience any issues. Getting the right speed is the key, and that speed was between slow/medium.

I've only used one of these bits so far to drill and tap a cross threaded hole in an alloy motorcycle frame. It worked fantastically did exactly what I wanted. I can't comment on life span or other applications but worked for me

Ok for price

Fantastic bit of kit, if seller does a larger set I would recommend purchasing. Quality of product good. I'd recommend a size chart for which drill bit to use for each tap and die, thanks!

Handy but still prone to snapping but do save time if they don't
