Because the consumables, a little cheaper than the hardware store, because the order together, there is also a delivery, it will be saved. Because the consumables, if possible, we'd like a set of PB products.

Initially, I was thinking if Bonus points several times in the open under the hole in the center punch instead ... and, we dull also very bite is also good sharpness. If there is no blurring of the commodity in the purchase of the next time is continuously you want to use products.

It has consumed three to processing 24 places. In the electrodeposition Dora work is the cause of the consumption that would fold accidentally requires quite thrust while 2.5mm and a small diameter. However, about three times that's normal drill because it requires this time has been satisfied. The contemplated improvements you want to buy if there is also a short form of length.

Sharpness was good. Since the number of times of use is small, durability is unknown.
