A drill tooth breaks during removal while using a drill to remove the bolt breaking. Successful removal with hard drill. It takes time, but we are satisfied that we can cope with the result cheaply.

It is good to have more cutting capacity than I expected, but I can take it if durability is over 3 times.

It can not be scraped as much as I thought, and it is useless if I use it once.

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.

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.

It is impossible with a drill 3 mm hole drilled in a carbon steel shaft. It was accompanied by trial and error to use by an amateur, and I got missing a tooth near the penetration. . Will it be cured by polishing ?, In the electric hand drill there is a risk of tooth chipping, but it is a point to push it slowly over time.

OS6 made M6 tap accidentally folded Can the hole be drilled with the same manufacturer's hard drill? Moreover, the tap is broken in a state of being stuck near 20 mm. Honest talk, I was not expecting ... With the fine feed of milling, I started awesome feeding. With dry cutting, I opened a 20 mm deep through hole in the M6 tap! Moreover, the screw thread was pulled out intact! Just like "Shogun and shield" wins! Great drill! OSG is not Date ♪

Sharpness is good. However, if the total length is 50 mm it is the highest. If other manufacturer's items have a total length of 50 mm or more, please introduce.
