Spiral tap

Precision thread cutting can be carried out reliably, finished without screw rattles, and it can be used for a long time as a tap.

It was very sharp. Compared with general trench type taps, it seems that the excretion of the facet is good.

There are also many times of use, but in particular this is not a problem at present.

Although it may be a monotary product, it is small in size. So, I made it to this. Because it is cheaper than group tapping.

I made a purchase to cut the set screw by my own T slot nut. M10 thought that it would be difficult to get rid of it, and with good sharpness the discharge of kiriko was also very satisfactory, but if the range of incomplete threaded part of calling was a little narrower it was a five star.

Although the width of the chip escape was larger than the diameter of the tap, there was also anxiety, but with a thickness of about 3 mm, the bottom hole of 1.6 mm was opened in the 6000 series aluminum plate. With this 2 mm tap, one screw could not be cut It is the lowest item that breaks into. Considering the trouble of removing the cutting edge that bites into the eyelet, it is better to cut out the other piece, but I do not want to buy the product of the manufacturer here even in the DIY work leaving it to no time. This is an honest impression.

Although it was discharged when the clipper was discharged in the item explanation, it got stuck in the groove and it was somewhat frustrating but it got drowned. I thought that the spiral tap (non-coated item) of YAMAWA used before this product was better.

It was sharp and good for the stainless steel material without occurrence of muscle etc. It was about 50 processing, so I would like to try it again at the next mass production.

Very sharp.
