I purchased it for use when tack welding such as gazette plate etc. of a place where temporary attachment first can not be used. Last time I bought a cheap type of MonotaRO specification of this product, but the right angle was 20 cm and 1.6 mm crazy and there was a loss of cheap buying. This time purchase is within 20 cm and less than 0.3 mm in the truss and there is personality. It can also be used with magnetic force. Depending on the thickness of the gazette, I feel that the magnetic force is insufficient, but if cleaning and contacting the contact surface is done, it is easy enough to work.
