Diamond Scriber

Product Overview

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.

Application

• Cutting and processing of compound semiconductors (gallium arsenide, gallium phosphide, indium phosphide), sapphire, glass, etc.

Product Features

1) Single-Point Type (Conical Type) A single-point scriber has a conical tip with a rounded edge at its very tip. It is currently the most commonly used type.
2) 2-Point Type A 2-point scriber is a scriber with a flattened cutting edge, created by retaining two opposing points of a 4-point scriber and removing the other two opposing points.
(3) 3-point type 3-point scribers are ground into a triangular pyramid with a triangular flat section at the tip.
4) 4-Point Type A 4-point scriber has a shape formed by cutting off the tip of a square pyramid so that it is parallel to the base; the tip is square.
(5) 8-point type The 8-point scriber has a very thin heel point and a shape that provides a smooth line and good braking.

We manufacture various types of scribers according to the number of points. Special products (narrow angle specifications) are also available upon request.
