Various Size Sic Honing Brush As Brush Hone Fro Deburring And Finishing
A SIC (Silicon Carbide) honing brush, often referred to as a "flexible hone" or "brush hone," is a specialized abrasive tool used for internal diameter (ID) finishing and deburring. It is characterized by abrasive globules (beads) bonded to the ends of flexible nylon filaments.
With excellent flexibility and self-adaptability, it perfectly fits inner bores, irregular holes and cross holes, efficiently completing honing, deburring, edge rounding and surface finishing in one process. It delivers uniform cross-hatch surface texture, stable roughness and no scratch damage to workpieces.

1. Structure & Material
Abrasive Media: High-hardness silicon carbide (SiC) grit (60#–1000#), providing sharp cutting and long wear life.
Filaments: Flexible nylon strands, enabling self-centering, self-aligning, and self-compensating for wear, ensuring uniform contact with bore walls.
Shank: Rigid steel core for clamping in drills, CNC spindles, or honing machines.
Shape: Typically ball-shaped abrasive tips arranged in a cylindrical brush form, ideal for deep and complex bores.
2. Key Features & Advantages
Flexible & Uniform Finishing: Adapts to bore irregularities; delivers consistent cross-hatch finishes (e.g., 45°) for oil retention and piston ring seating.
Deburr & Polish in One Step: Removes micro-burrs, edge breaks, and glaze while refining surface roughness (Ra 0.2–1.0 μm).
Non-Damaging: No metal contact; avoids scratching or deforming soft/hard materials.
Wide Applicability: Works on mild steel, stainless steel, cast iron, aluminum, and alloys.
Cost-Effective: Reusable, long-lasting, and compatible with automated equipment (CNC, robots).
3. Main Applications
Automotive: Engine cylinders, valve guides, piston pin bores, brake caliper holes.
Hydraulics & Pneumatics: Cylinder tubes, valve bodies, hydraulic hoses, bearing bores.
General Machining: Cross-hole deburring, blind hole finishing, tube ID polishing, mold pin holes.
Aerospace & Precision Parts: High-precision bores, actuator components, and medical device parts.
4. Specifications & Selection
Diameter: 3 mm–300 mm (custom sizes available).
Grit Size: 60#–120# (rough deburring), 180#–320# (general finishing), 400#–1000# (mirror polishing).
Length: 50 mm–600 mm (customizable).
Speed: 500–3000 RPM (dependent on material and diameter).
