Features of Osakada Tool Chisel


Uncompromising attitude towards quenching

Our company was founded in 1966 as "Osakada Heat Treatment Works". We specialize in heat treatment processing and have manufactured various products.
We have been particular about "quenching" and "tempering", which are the processing processes, since the beginning and devote sufficient time and technology to maintain the highest quality.


Strict process control and hardness inspection for all products

We keep records of all manufacturing processes, including the temperature and water temperature during quenching and tempering, and inspect the hardness of each chisel.
When problems occur, we will verify them and try to solve the fundamental problem.


Development design with those who would use it and the place it would be used in mind

Our products are used not only for new construction sites, but also for demolition of buildings in disaster-stricken areas. We are aware of the role of protecting people's lives and creating new places of life, and create products that meet expectations.
We also propose products that are economical and workable, and reduce the burden on people who work in the field.

Please leave anything from OEM to custom made orders to us

We also manufacture OEM products that are prepared in response to requests from aircraft manufacturers such as breakers,
and custom-made products that meet special usage conditions and requests.
