In-Machine Deburring & Surface Improvement for CNC Applications Stem-Mounted End abrasive filament brushes are designed for in-machine deburring, hole deburring, internal feature deburring, and surface improvement applications in CNC machining environments. The compact stem-mounted design allows the brush to reach smaller openings and difficult-to-access areas while providing controlled deburring performance and consistent edge quality. Commonly used in CNC machining centers, robotic deburring systems, and automated edge finishing applications, Stem-Mounted End Brushes are particularly effective for moderate burr removal, surface conditioning, and precision deburring within internal geometries and machined features. Common Applications Hole deburring Internal feature deburring Surface improvement In-machine deburring Moderate burr removal Edge preparation CNC deburring Key Features Compact stem-mounted design for internal feature access Effective for hole deburring and smaller machined areas Designed for controlled in-machine deburring applications Supports surface improvement and edge preparation Available in multiple diameters and mounting configurations Compatible with CNC machining centers and robotic deburring systems Available Configurations Brush Diameter Filament Grit Filament Diameter Max RPM Part Number 1/2" 120 0.040" 4,500 FM-DBR-0220001 3/4" 120 0.040" 4,250 FM-DBR-0220002 1" 120 0.040" 4,000 FM-DBR-0220003 2" 120 0.040" 3,750 FM-DBR-0330001 3" 120 0.040" 3,000 FM-DBR-0330005 4" 120 0.040" 2,750 FM-DBR-0330010 Application Notes: 1/2", 3/4", and 1" brushes are ideal for light machining burr removal and surface improvement. 2", 3", and 4" brushes are designed for demanding deburring of stainless steel, hard alloys, machined parts, and aluminum components.
