Manufacturing that is close to people's hearts with technology and quality

For more than 50 years since the founder's grandfather started the heat treatment processing industry, we have been developing and manufacturing a tool "chisel" that is attached to the tip of electric hammers and hydraulic excavators to process and crush rocks and concrete.

The products are used not only in Japan but also in construction sites, quarries and mines around the world such as Asia, the Middle East and North America.

By constantly expanding our knowledge, refining our technology, and making things with all our heart, we have received high trust and many requests from our customers, even though we are "only Chisel".

We pride ourselves on providing products that meet expectations with certainty in infrastructure work, construction and civil engineering work.

On the other hand, the products we make are sought after and used not only in hopeful new development areas but also in sad sites damaged by disasters.

Every time we learn from customer information and media that our products are used in such places, all employees are renewed in their efforts to create products that do not disappoint.

Whether you're moving forward or overcoming sadness.

We always keep in mind someone's "feelings" and will continue to manufacture products that are close to those who need them.
