Various wires are attached to the wiring and piping of the engine at the time of making the model of the car by the car, but this drill is used because it is difficult to pass through the drill hole with the same diameter as the wire.
Work efficiency is considerably different only when the hole diameter is 0.05 mm larger.
I am using it pleasantly.
As expected it is the quality of a brand item. Moreover, with a rugged case, it is a thought that you can protect precision cutting edge. That's an exception! If it is about to be used on a photosensitive substrate (glass epo), there is no spilling of the blade until I die (laugh)
I bought it for processing of glass epo. Until now I used a drill for ironworkers but switched to this item. The quality of ordinary drill and glass eep processing is unchanged. However, the trouble of replacing the drill blade has been reduced. I am using 0.8, 1.0 and 1.2 mm drill blades, but that point is convenient as the length and mounting diameter are the same. However, if the drill blade is very fragile, hit it for a moment or hook it, the blade edge is blistering. Please take care.
