XLO Excello Diamond Tools

Braemar USA XLO Ex-Cell-O Diamond Tools are precision single-point diamond dressers designed for Ex-Cell-O thread grinders and compatible grinding equipment. Each tool features a small, sharp diamond point that accurately dresses and profiles conventional abrasive grinding wheels.
Precise wheel geometry is essential in thread grinding because minor dressing variations can affect thread angle, pitch diameter, form accuracy, and surface finish. Therefore, Braemar USA manufactures XLO diamond tools to provide clean dressing action, stable point geometry, and repeatable production performance.

Precision Diamond Dressers for Ex-Cell-O Thread Grinders

XLO Ex-Cell-O Diamond Tools remove dull abrasive grains and loaded bond material from the grinding-wheel surface. This process exposes fresh cutting points while restoring the wheel’s required shape and concentricity. As a result, the wheel cuts more efficiently and maintains a more accurate thread profile.
The rigid steel shank securely supports the diamond during dressing. In addition, controlled diamond exposure helps reduce vibration, chatter, and premature point failure. These features make Braemar XLO diamond dressers an economical solution for both production grinding and tool-room applications.

Thread-Grinding and Dressing Applications

Braemar USA XLO Ex-Cell-O Diamond Tools are suitable for:
• Precision thread grinding
• Grinding-wheel form dressing
• Wheel truing and conditioning
• Thread-angle generation
• Profile and contour dressing
• Tool-room wheel maintenance
• Automotive and aerospace component production
• Bearing and precision-fastener manufacturing
• High-volume production grinding
These diamond dressing tools are commonly used with conventional aluminum-oxide and silicon-carbide grinding wheels. However, the correct tool depends on the wheel abrasive, bond, grit size, diameter, and required profile.

Standard XLO Diamond Tool Configuration

The standard Ex-Cell-O-style tool has a 3/8-inch-diameter shank with a 1-5/8-inch overall length. Braemar USA also offers other shank sizes and styles for specialized machines and dressing systems.
Available diamond grades and sizes include:
• DDT0150: Standard grade, 0.07–0.08 point
• DDT0155: Select grade, 0.07–0.08 point
• DDT0160: A-grade, 0.08–0.09 point
• DDT0165: AA-grade, 0.08–0.09 point
• DDT0170: AAA-grade, 0.09–0.10 point
Selecting the proper diamond grade helps balance initial cost, point quality, form retention, and service life. Higher diamond grades are recommended when tighter tolerances and longer-lasting point geometry are required.

Standard and Custom Ex-Cell-O Diamond Dressers

In addition to standard XLO Ex-Cell-O Diamond Tools, Braemar USA can manufacture custom shank dimensions, diamond sizes, point radii, and tool geometries. These options allow the dresser to match specific machines, wheel specifications, thread forms, and production requirements.
