About

Konghwa Precision Tool grew out of a cutting-tool business founded in 1970 and set up its own manufacturing in 1990. It became the first company in Korea to produce the Speed Power Drill, a solid carbide drill for steel, and now sells its tools in Korea and overseas.

The Ansan factory makes two product families: carbide drills (micro, medium, long, coolant-through and brazed oil-hole types) and solid carbide end mills (square, ball, aluminium and graphite types).
