basic information
1. A hexagonal chip that excels in strength and economy. 1) The chip thickness is 6.35 mm, which is thick, and the cutting edge cross-sectional strength relative to the mounting hole diameter is improved by 40% compared to conventional products. 2) The chip sits well, allowing for stable cutting without chatter even during rough machining. 3) The outer circumference and front cutting edge angles are relieved in relation to the machined surface, reducing cutting resistance during machining. 4) It achieves high cutting depth and feed processing with a maximum cutting depth of 5 mm and a feed rate of 1 mm per edge (when using 7 corners). 5) The cutting depth can be up to 12 mm (however, the use of 7 corners is not allowed). 2. Adopting "G-Body" made of heat-resistant, tough steel + GN treatment. 1) With a surface hardness of over 65 HRC, it is highly hard and resistant to thermal deformation, providing high rigidity and increasing the durability of the main body and tool life by over 30%. Additionally, it suppresses the adhesion of chips and the occurrence of rust. 3. The chip has corner identification numbers (1 to 7) displayed, making it easy to identify the used chip corner. 4. The chip materials include "JC7560" and "JC5040" for general steel, "JC5118" and "JC8015" for cast iron and hardened steel, and "JC7560" and "JC8050" for stainless steel and high intermittent cutting.

Applications/Examples of results
Recent high-feed cutters cannot perform deep cuts, which results in longer air-cutting times and inefficient processing for workpieces with uneven allowances, such as cast iron and cast steel. On the other hand, round chip types can perform deep cuts but have high resistance, preventing an increase in feed rate. Heptamil has been developed as a high-efficiency processing tool that compensates for both of these drawbacks. Please feel free to contact us.

Company information
Since our founding in 1938, we have recognized the potential of cemented carbide in industry and have independently pioneered innovations in cemented carbide tools and the evolution of processing. Based on the powder metallurgy technology cultivated in cemented carbide manufacturing, we have successively introduced innovative technologies to the market, including the world's first practical application of conventional cermet chips, the development of ball end mills and drills with spiral cutting edges, and end mills with twisted cutting edges. In recent years, we have created highly original new technologies in various fields, such as diamond and cemented carbide integrated sintered products, cemented carbide for irregular gear forming molds, and tool materials made from rare metal-reduced alloys, which we sell worldwide. In addition to developing materials and products, we consistently conduct in-house production from the preparation of raw powders, ensuring stable high-quality products, which we believe has earned us the trust of our customers. Today, there are very few products in the world that do not undergo machining processes such as cutting or plastic processing. Even in the realm of advanced science, the advancement of processing technology is essential for practical application and industrialization. In this era of global competition, we will challenge new fields without being bound by convention, adhering to the philosophy that "management is creation" and "richly creative technology development" to contribute to the world.
