Tap removal
From Japan
On 2016-08-04 10:16:59
It can not be scraped as much as I thought, and it is useless if I use it once.

Removing a broken 4M tap
From Japan
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
From Japan
On 2016-04-27 14:49:06
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.

Drilling hard shaft
From Japan
On 2015-10-29 15:59:54
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.

Elimination of damaged taps
From Japan

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 ♪

Drilling of superhard board
From Japan

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.

Breakage tap removal
From Japan
On 2013-06-27 17:08:45
I broke the tap and got lost as a carbide drill to remove it, but I worked with a drilling machine purchased here at Mochi Rice cake shop, so I removed a core a bit but managed to remove somehow Although it is nice, I think I will use a milling machine at a moment

MonotaRO TIN-I-SFT M6 x 1 Tin coat spiral tap As breakage tap removal
From Japan
On 2012-05-18 00:43:05
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.
