Removing a broken 4M tap
On 2016-06-15 19:51:11
I set it in the milling machine and it broke at about 5 mm from the tip after 2 minutes of work start. Depending on the conditions, you may be able to punch well, but it seems to be an unreasonable task for amateurs. It took almost half a day to recover from this frustration.
Using a battery type electric drill

Although it is certainly being scraped, its speed is very slow and it is 3 hours and it is about 6 mm. The drill broke out of the middle of that. Perhaps it was bad, but I was not convinced.
MonotaRO TIN-I-SFT M6 x 1 Tin coat spiral tap As breakage tap removal

We confirmed the cutting conditions with OSG HP, but we did not know, so temporarily spindle rotation number 1,800 rpm, dry cutting was done. First of all, after breaking the tap part with a diamond rotating grinding stone, making it almost flat, cutting the hard drill to reduce the hard drill and cutting it into a breakable tap part, it can not cut totally. Hardness difference with spiral tap was hardly felt. After all, we abandoned the removal of tears on the way. ⇒ I would be pleased if you can ask the working maker of the milling machine whether there is an error in the method of use.
