Abstract
It is an important problem that many handicrafts in the foundry are mechanized and efficiency is promoted. But those mechanical tools are generally apt to be so severely handled beyond their abilities that the utmost attention must be paid. I am about to explain the examples that electric tools such as the electric drill, portable saw, the tamper motor, coal drill motor etc., which are now sold in the market, are very useful when used with drilling and cutting of the mold and bricks, vibrating screen, feeder, belt conveyers, mixers etc.
