With our processing know-how and a wide selection of diamond/CBN blanks, we offer standard and custom-made products and also special specification (chip breakers, wipers, etc.) designs to improve productivity in processing various materials (aluminum, nonferrous metals, hardened steel, cast iron, sintered metals, etc.

To meet the market demand for higher productivity, we developed helical type drills with a diamond compact to achieve rapid feeding and reduces thrust. Also available are special types that solve exit burr and chip obstruction problems.
They also enable process integration by adopting one-pass finish and multistep edges.

[Endmill]
Purposely designed edges to cater for your needs to improve the efficiency of various types of processing such as milling, grooving, spot facing, and curve facing. Also available are spiral types for high-speed cutting, high-precision ball shapes, and taps. Applications include high-precision and high-efficiency processing of metal molds, compressors, FRP, acrylic, etc.
[Routers & Tipped Saw]
They allow you to cut costs because they produce a long lasting surface finish in cutting, grooving, and boring of wood, building materials, printed-circuit boards, artificial marble, plastics, etc. and have a long life, Also, we meet a wide range of demands such as whole form processing by combining them.

By integrating the tooling holder and reamer into a single unit, tool length can be shortened and rigidity can be increased to meet high precision requirements. Also, we can be manufactured in accordance with various holder standards.

With a focus on consistent quality based on the control of key reamer specifications—such as outer diameter and runout tolerance—our designs can accommodate high-precision requirements, including surface roughness, roundness, and concentricity, as well as high-speed feed rates. We meet our customers’ needs with a wide range of products, from standard specifications to value-added options.

"SUNBRIGHT" is a monocrystalline diamond cutting tool for ultra-precision cutting.
The sharp cutting edges and nano-order level contouring accuracy have been established through high-precision machining technology.
It can be used for various lens products, lens molds, and mirror finishing of non-ferrous metal products.

This is a core drill designed for drilling holes in automotive glass, which plays a crucial role in improving vehicle safety. It features a chamfering section that performs chamfering simultaneously with drilling, helping to streamline the manufacturing process.

These tools are used for cutting hard, brittle materials such as compound semiconductors (gallium arsenide, gallium phosphide, indium phosphide) and sapphire. Some types feature rough diamond that has been machined into a conical shape (1-point) or into cutting edges with 2, 3, 4, or 8 points, depending on the application. Since no grinding fluid is used, no processing facilities are required, and the fine scribing line allows for a high number of “chips” to be obtained.Compared to standard cutters, chipping during breaking is minimized, and you can select the optimal “point” shape.

Cutters with a metal base are available in "multi-cutters" and "single-blade types. Multi-cutters can cut and groove by combining multiple cutters with specifications suitable for the work material. Our unique technologies such as cutting edge shape, pitch accuracy, and accumulation accuracy realize high machining quality. The single-blade type is a cutter with a diamond or CBN abrasive grain layer formed on the periphery of the steel steel core. Electroplated, metal, or resin can be selected for the bond, and the cutting edge shape (V-shape, R-shape) and steel core shape (all relief, under-neck relief) can also be selected according to requirements.

Dicing blades come in two types: “hub type” and “ring type.” The hub type is primarily used for dicing semiconductor silicon and compound wafers. It features an aluminum base and a nickel-bonded diamond layer integrated into a single unit, making it easy to handle. The ring type can be used for a wide range of applications, including cutting and grooving not only semiconductor silicon and compound wafers but also various packaging materials and electronic component materials.There are three types of bonds to choose from: electroformed, metal, and resin. The electroformed bond allows for the production of ultra-thin blades with a thickness of 15 μm.Resin bonds are frequently used for cutting glass, ceramics, and various packages such as QFNs, where chipping and cutting resistance must be minimized. Metal bonds offer a wide range of options—from high-rigidity types comparable to electroformed bonds to types with superior cutting performance—allowing you to select the bond best suited for your specific workpiece material.

This core drill offers superior precision and cutting performance. It is suitable for a wide range of materials, including LED substrates, semiconductor materials such as sapphire, and ceramics.
