Impregnated Diamond Dresser (Rectangular Segment)

Braemar USA Rectangular-Segment Impregnated Diamond Dressers provide aggressive, consistent conditioning of conventional abrasive grinding wheels. Also known as diamond nib dressers, these tools contain multiple layers of sharp diamond particles distributed throughout a durable metal-bond matrix.
As the rectangular working segment wears, new diamond particles are continuously exposed. This self-renewing action maintains effective dressing performance without requiring the operator to rotate or reset a single diamond point.

Heavy-Duty Grinding-Wheel Dressing

Unlike a traditional single-point dresser, an impregnated diamond dresser uses many cutting points simultaneously. The rectangular segment provides a broad, stable contact area that distributes dressing forces across the working face.
This design allows the tool to remove larger amounts of wheel material while maintaining consistent cutting action. Therefore, Rectangular-Segment Impregnated Diamond Dressers are well suited for large-diameter wheels, wide wheel faces, production grinding, and applications where single-point tools wear too quickly.

Benefits of Rectangular Impregnated Diamond Dressers

• Multiple layers of diamond grit in a metal-bond matrix
• Self-renewing cutting action as the segment wears
• Broad rectangular face for stable wheel contact
• Efficient removal of grinding-wheel material
• Consistent performance throughout the tool’s service life
• No diamond-point rotation or resetting required
• Excellent wear resistance in high-production applications
• Restores wheel flatness, concentricity, and cutting action
• Helps reduce wheel loading, heat, vibration, and chatter
• Available in fine, medium, and coarse diamond grits
• Straight and angled working faces available

Straight and Angled Dresser Configurations

Braemar USA offers several rectangular-segment designs to match different wheel shapes and machine-clearance requirements:
• Straight segments provide uniform contact for flat wheel faces and general straight dressing.
• 15° front-angle segments improve access and contact on specific wheel profiles or machine setups.
• 15° side-and-front-angle segments provide additional clearance for specialized dressing operations.
The correct configuration depends on the grinding-wheel dimensions, machine design, dresser holder, and required wheel profile.

Grinding-Wheel Compatibility

Braemar USA Rectangular-Segment Impregnated Diamond Dressers are commonly used with:
• Aluminum-oxide grinding wheels
• Silicon-carbide grinding wheels
• Conventional vitrified-bond wheels
• Selected resin- and rubber-bond abrasive wheels
• Large-diameter grinding wheels
• Wide-face production wheels
• Coarse-, medium-, and fine-grit abrasive wheels
Dresser selection should be based on the wheel abrasive, bond, grit size, diameter, width, and required surface condition. Matching the diamond grit and metal matrix to the wheel specification improves dressing efficiency and tool life.

Common Grinding Applications

Rectangular Impregnated Diamond Dressers are well suited for:
• Centerless grinding
• Cylindrical and OD grinding
• Surface grinding
• Straight-face wheel dressing
• Grinding-wheel truing and conditioning
• Large-diameter wheel maintenance
• Heavy-duty wheel-material removal
• High-volume CNC and manual grinding
• Automotive and bearing manufacturing
• Steel and precision-component production

Standard and Custom Diamond Nib Dressers

Braemar USA can also manufacture custom segment dimensions, shank sizes, overall lengths, face angles, diamond grit sizes, concentrations, and matrix formulations. These options allow each dresser to match the grinding machine, wheel specification, and production requirements.
