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 are available in "hub type" and "ring type." The hub type is mainly used for dicing silicon and compound wafers for semiconductors. The hub type is mainly used for dicing silicon and compound wafers for semiconductors. The aluminum base and nickel diamond layer are combined into a single unit, making it easy to handle. The ring type can be used for a wide range of cutting and grooving of various PKG and electronic component materials in addition to semiconductor silicon and compound wafers. Three types of bond can be selected: electroformed, metal, and resin. The electroformed bond can produce an ultra-thin blade with a thickness of 15 μm. The resin bond is often used for cutting glass, ceramics, QFN, and other PKGs where chipping and cutting resistance must be suppressed. Metal bond can be selected from a wide range of bond lineups, from high rigidity types comparable to electroforming to types with excellent cutting performance, to suit various work materials.

Thin-blade type band saw with diamond electroplated on a high-tensile steel band. It cuts large-diameter silicon ingots and other large-diameter work materials efficiently with high precision. It is also used for cutting carbon, ceramics, glass, and other materials, and can be manufactured in sizes compatible with various machines.
The segment type is suitable for cutting brittle materials and has excellent cutting performance and long life. It is especially suitable for high-precision and high-efficiency cutting of single crystal silicon.
The serrated type is widely used for wide products and demonstrates excellent sharpness for cutting difficult-to-cut materials, and is also ideal for cutting work materials that are prone to blade edge clogging.
The continuous type is used for a wide range of applications from narrow to wide products. The continuous electroplated layer on the cutting edge reduces saw marks on the cutting surface of the work material and is effective in cutting hard work materials.

Developed to expand the processing area of resin bond wheels, such as lapping, mirror finishing, polishing, etc., with a new bond with a special structure that has a high elasticity not found in conventional Bright Star type bonds.
