“Chamfering” is performed in most parts machining, regardless of the shape or material of the product. Because chamfering operations represent a small percentage of the overall process, many people may view chamfering as a simple task. However, revisiting chamfering can significantly improve manufacturing efficiency. This is an especially important for mass production sites, which are common in Vietnam.

In this article, we will introduce the chamfering tools of Iwata Tool, a company highly regarded within the industry for its center drills and known for achieving high-speed chamfering through its unique technical capabilities and innovative approach.

▲ Examples of machining with Toglon® Multi-Chamfer

In general, chamfering is one of the least profitable processes within machining. Therefore, we developed this product to address the challenge of customers who simply want to shorten processing times. While chamfering tools are typically multifunctional, we received feedback from customers that they often do not require such versatility in a single tool at mass production sites. In response to this demand, we deliberately focused solely on chamfering, stripping away unnecessary features. This approach allows us to maintain a competitive price despite the multi-blade specifications." (President Iwata, Iwata Tool)

Establishment of Stock Center in Vietnam

Iwata Tool already had overseas bases in China (sales) and Thailand (manufacturing & sales). In April 2023, the company established a stock center in Hanoi, Vietnam, enabling it to maintain inventory locally. This setup facilitates smooth supply not only of the conventional products but also of microfabrication tools and original products manufactured in Thailand, resulting shorter delivery times.

At Ueno Vietnam, we collaborate with Iwata Tool not only for the sale of tools but also to provide recommendations on selecting appropriate tools for specific applications and advice on usage environments. If you are facing challenges with chamfering processes, please feel free to consult with us.
