Material
Diamond Abrasive Filament
Diamond Abrasive Filament is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. The same material can produce different stiffness, so filament diameter, trim length, density, grade, and service conditions must also be defined.
Material Overview
Diamond abrasive filament is a polymer monofilament containing diamond abrasive particles that expose cutting points as the filament wears.
In a finished brush, Diamond Abrasive Filament does not create a fixed stiffness by itself. Brush force and recovery come from the complete filament geometry and contact setting, not just the polymer name. Service conditions must also be considered.
Material Properties
| Abrasive grit | 120–3,000 grit diamond |
|---|---|
| Filament diameter | 0.20–1.50 mm |
| Mohs hardness | 10 |

Frequently Asked Questions
What are the key properties of Diamond Abrasive Filament brush material?
Diamond abrasive filament is a polymer monofilament containing diamond abrasive particles that expose cutting points as the filament wears. Direct data: Abrasive grit: 120–3,000 grit diamond; Filament diameter: 0.20–1.50 mm; Mohs hardness: 10; Brush operating range: -20–120°C for nylon-bound filament.
Where is Diamond Abrasive Filament used in cleaning brushes?
Micro-deburring, edge radiusing and precision finishing of carbide, ceramic, glass and other hard materials.
How does filament geometry change Diamond Abrasive Filament brush stiffness?
Diamond Abrasive Filament changes brush stiffness through filament diameter, free trim, density, crimp, and contact. Use finer filament and longer trim for conformable contact; use coarser filament, shorter trim, or higher density for stronger displacement or cutting.
When should Diamond Abrasive Filament be replaced by another material?
Compare Diamond Abrasive Filament with Silicon-carbide abrasive nylon, aluminum-oxide filament, ceramic abrasive filament. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
