About Us

Taper shank, stepped spacer, extension spacer and the body have two screw holes at a 90 degrees distance on the sides. Except taper shank, the stepped spacer, extension spacer and the body have a pin. A hole can also be found at the bottom of taper shank, stepped space and extension spacer. With these features of two screw holes, a pin and a bottom hole, the combination of taper shank with any of the stepped spacer, extension spacer and body, makes a tight lock in the system as it makes a strong interaction; thus, showing a more rigid feature of our modular boring system.

Besides being rigid, the modular boring system is also very flexible. Its flexibility allows the system to easily adapt to process various sizes and depth of the hole of the diameter.

In naming the outer diameter of the taper shank, extension spacer, stepped spacer and boring head, we used the symbol “H” followed by a number, which represents the size of the outer diameter. For instance, H25, wherein in “H” is the symbol while 25 is the value of the outer diameter. Hence, in this series, there are H25, H32, H40, H50, H63,H80 and H100 system. And 1143, BMH, HNBJ16, NBH2084, HBDR, h100-B72, h100-AL120 and HRBH system.

Ideal tools to block and position pieces with high precision, both for machining and checking. They are suitable for grinding and milling machines, working centers and electron discharge machines.

NK type high precision vise material is SKS3.
NTA type high precision vise material is SUS440C.
