AccuScribe diamond tools
The best line, every time
DDK AccuScribe diamond tools have proven to be the best choice for reducing costs and improving yields. Each tool is precisely made with centered tables, collinear edges and accurate angles to dramatically reduce setup and changeover cost. These accurate, long-lasting tools provide a narrower scribe line to improve your scribe and break operations.
Use the guide provided below to select the tool that best fits your application.
Exceptional service from prototype through retirement
DDK engineers work closely with customers to make their design ideas a reality. Our experience in design engineering, manufacturing, and service has made DDK the industry standard for improving scribe and break technology. Dedicated processing equipment ensures product consistency. And, as with all our products, our AccuScribe tools come with an unconditional guarantee and exceptional customer service.
The difference is the diamond
DDK engineers have incorporated extensive knowledge of diamond and years of experience to develop affordably priced diamond scribe tools. All DDK products are made in the USA with the finest materials, the most precise equipment, the highest level of craftsmanship, the most exhaustive testing program, and the strongest guarantee available. DDK makes an entire range of standard diamond scribing tools - those with two, three, four and six edges.
Our tools are used in scribe and break technology for:
- Optical detectors
- Light emitting diodes (LEDs)
- Laser diodes
AccuScribe diamond tools fit Dynatex, Loomis and other scribe and break machines for semiconductor wafer dicing.
The scribe and break process is ideal for III-V compounds and other materials like:
- Gallium arsenide
- Indium phosphide
- Silicon germanium
Guide to AccuScribe tools

6-point tools designed for harder materials
All diamonds used are gem-quality with pale yellow or better color. Raw diamond is free from inclusions and shows only minimal stress under cross-polarized light. Near-perfect crystals are chosen so that structure is optimal.
Selected diamonds are positioned to provide the most accurate, durable edges. We orient the diamond for optimal mounting with the desired crystalline plane, so that facets can be polished for perfect edges and points with superior durability.
Diamonds are mounted to ensure a tight grip during processing and use. DDK uses a proprietary braze in combination with magnetic, thermally stable shank materials.
Diamonds are precisely sharpened using the finest diamond powder and most accurate lap spindles available.
The edges and points of each AccuScribe diamond tool are inspected at high magnification to ensure quality. Edges and points are inspected at 60x during manufacture and 400x afterwards. Angles and dimensions are measured on an optical comparator at 50x. This data can be traceable to each tool through a unique serial number to help you with application testing or troubleshooting.
