Sturdy 10.5mm Cross Hole Power Deburring Tool Oval Head Knotted Drilling Brush Abrasive Wire Bore Cleaning Brush for CNC Automated
Product Description
-
Oval Head Knotted Drilling Brush (often classified as an internal cross-hole deburring or bore brush) is a high-impact, specialty industrial tool designed for automated or manual drills.
-
Unlike standard straight cylinder bottle brushes, the wire configuration expands slightly into an oval or football-shaped silhouette before twisting tightly into rigid knots
-
The special feature: triangular piano wire is used as the trimming, which is additionally twisted again around its own axis.
-
This specific combination of an oval profile and twist-knot wire provides high-intensity, aggressive mechanical force required to remove heavy burrs from difficult-to-reach intersection
The Engineering Benefits of Polyflex Encapsulation
- Maximum Aggression: By encasing the length of the wire in elastomer, the bristles are completely prevented from flexing or bending backward. This channels 100% of the drive motor’s kinetic energy directly into the tips, producing a rigid, high-impact scraping action ideal for stubborn coatings.
- Zero Inefficient Flare Out: Standard wire brushes flare outward like a fan at high RPMs due to centrifugal force, which reduces control and alters the contact area. Polyflex brushes preserve a perfectly consistent, tight brush face geometry under high speeds.
- Enhanced Operator Safety: Filament fracture caused by metal fatigue from continuous flexing is the primary cause of wire shedding. The rubber casing dampens structural vibrations, virtually eliminating wire breakages and hazardous flying wire shards.
- Clean Wear Profile: The elastomer disintegrates cleanly into a fine, non-marking powder dust along with the eroding steel filaments

Operating them past their maximum rated RPM can throw off the tool's balance, snapping or bending the center drive shaft.
- Guide Before Spinning: Always insert the oval head completely inside the tube or hole before engaging the drill trigger. Spinning a long-shanked, top-heavy brush in open air causes the shaft to whip back violently, creating a severe injury hazard.
- Reciprocating Stroke: To maximize efficiency, do not just hold the spinning brush still. Use a gentle "in-and-out" stroking technique parallel to the bore line so the sides of the oval head properly stroke across the internal cross-hole lip
