Our aluminum oxide diamond end brush is manufactured from aluminum oxide and diamond abrasive nylon and engineered for deep hole deburring, with key advantages including aluminum oxide (ao) abrasive and diamond abrasive.
Also known as AO diamond end brush, custom aluminum oxide diamond end brush or industrial end brush.
Customizable according to customer requirements – brush diameter, filament length, and base plate dimensions fully tailored to match specific deep hole, long tube, and complex channel geometries.
This brush is built from 2 material groups – the extended-length aluminum oxide (ao) abrasive nylon and steel plate:
Our Extended-Length Unshanked Abrasive Nylon Filament End Brush features extra-long abrasive nylon filaments with no integrated steel shank – only a steel plate resin-injection molded base. This design allows users to attach their own extension rods, flexible shafts, wire ropes, or custom fixtures, providing unmatched reach for deep holes, long tubes, bent pipes, serpentine flow channels, and blind bores with high depth-to-diameter ratios.
Abrasive Options:
In practice the same brush is specified as hole deburring tools metal, internal hole deburring tool or metal hole deburring tool depending on the application.
Q1: What is the difference between AO and diamond abrasive options for this brush?
AO (aluminum oxide) abrasive provides gentle, controlled cutting action for soft non-ferrous metals – aluminum, copper, zinc – without damaging anodized or coated surfaces. Diamond abrasive delivers ultra-high hardness and extended self-sharpening life for hardened steels, titanium alloys, tungsten carbide, ceramics, and 3D-printed metal parts requiring maximum wear resistance and premium finish quality.
Q2: How do I mount this brush onto my equipment?
The brush features a steel plate resin-injection base designed for user attachment. You can mount it to your own extension rods, flexible shafts, wire ropes, or custom fixtures using standard mounting methods. This unshanked design provides maximum flexibility for deep hole, long tube, and complex channel applications.
Q3: What is the advantage of the extended-length filament design?
Extended-length filaments provide significantly greater reach than standard brushes, enabling access to deep holes, long tubes, bent pipes, serpentine channels, and blind bores with high depth-to-diameter ratios. The long filaments also conform to irregular internal cavities and complex geometries that rigid tools cannot reach.
Q4: Can this brush be used in automated CNC applications?
Yes, when properly mounted on compatible extension rods or tool holders, this brush is fully compatible with automated CNC machining centers. The consistent abrasive performance and chemical resistance make it suitable for high-volume automated production with minimal tool change downtime.
Q5: What is the recommended operating speed and technique for this brush?
For optimal performance, operate at speeds based on brush diameter and abrasive type. Generally, use lower speeds (500-1500 RPM) for larger diameters and higher speeds for smaller diameters. Always start at lower speeds and increase gradually. The brush should be inserted into the bore before rotation begins, and only the filament tips should contact the workpiece – excessive pressure reduces brush life and may damage the workpiece surface.
