ATOPLEE Spiral Flute Tap, 5pcs Titanium Coated HSS 6542 Metric Machine Tap Set M3 M4 M5 M6 M8 [5 Sizes]

GREAT SET MUCH BETTER THAN NORMAL TAP USE TAPPING GREASE OR FLUID MINE CAME IN A HANDY SMALL PLASTIC BOX GREAT FOR KEEPING THEM TOGETHER

Used the M5 and M8 taps on marine grade stainless steel. Went through the 5mm thick steel like a knife through butter. Very pleased with the quality.

Terrible quality, broke tapping thin aluminium. I would not recommend this product, feels cheap as well. I got 3 holes tapped before the bit snapped under barely any pressure.

2 of the bits snapped on first use. One in steel the other in copper. Good idea though. Does save time.

Ease of use.

Bought these to try out Being a Maintenance Engineer, we use these a Lot.

Was excited to use these new taps and second hole and half the teeth snapped off
