Material Composition:
-
Filament Material: 0.7mm high-tensile stainless steel wire (corrosion-resistant)
-
Handle/Stem Material: Brass tube
Product Features:
-
Flexible expansion design – compresses for easy entry into primary bore, then springs open at cross-hole intersection for precise burr engagement
-
Self-centering action – lantern geometry naturally centers within the hole, providing uniform 360-degree deburring pressure to prevent over-cutting
-
0.7mm stainless steel filaments – perfect balance of rigidity for cutting and flexibility for contouring; corrosion-resistant with no carbon contamination
-
Protection of critical geometry – removes burrs without altering bore surface finish or critical dimensional tolerances
-
Achieve non-destructive polishing on internal intersections
-
Solve metal part burr problems in complex internal geometries that standard brushes cannot reach
Applicable Scenarios:
-
Hydraulic valve block cleaning & polishing – ensuring clean, burr-free passages to prevent seal damage and valve sticking
-
Automotive engine component cleaning – cleaning oil galleries and coolant passages where micro-burrs could lead to catastrophic engine failure
-
Fuel injection systems – perfect for high-precision components requiring absolute cleanliness
-
Pneumatic manifolds – removing internal flash and burrs to ensure consistent air pressure and flow
-
Precision aperture打磨 (grinding) for cross-drilled holes in hydraulic and pneumatic systems
-
Solve cleaning problems of compressor fittings with complex internal passages
-
Fluid power equipment fittings machining – ensuring smooth flow paths
Why Choose Our Lantern Brush?
Deburring the intersection of cross-drilled holes has long been a challenge in precision engineering. Standard tube brushes cannot effectively reach or clean these internal junctions. Our lantern brush (cross hole deburring tool) is specifically engineered to navigate these difficult internal geometries.
The unique expandable "lantern" shape, made of 0.7mm high-tensile stainless steel wire, provides a flexible yet aggressive solution for cleaning internal junctions. When inserted into the main bore, the brush compresses; upon reaching the cross-hole intersection, it springs open, allowing the wire tips to engage directly with burrs at the precise point of intersection.
This tool is indispensable for industries where fluid power and airflow are critical. Unlike rigid boring tools, the lantern brush removes burrs without altering the bore's surface finish or critical dimensional tolerances – helping you meet precision tolerance requirements while reducing manual grinding cost.
Comparison with Standard Tube Brushes
| Feature | Lantern Brush (This Product) | Standard Tube Brush |
|---|---|---|
| Cross-hole deburring | Excellent (self-centering) | Poor (cannot reach) |
| Entry into small bores | Compressible design | Fixed diameter |
| 360° uniform pressure | Yes (self-centering) | Uneven |
| Risk of bore damage | Low | Moderate |

Frequently Asked Questions (FAQ)
Q1: What makes the "Lantern" design better than a standard tube brush for cross-holes?
A: A standard tube brush often passes over the cross-hole without enough outward pressure to grab the burr. The Lantern Brush is pre-stressed to expand into the cavity of the cross-hole, ensuring that the wire tips actually "hook" and shear off the burr at the intersection.
Q2: Will the 0.7mm stainless steel wire scratch my precision-honed bore?
A: Our stainless steel wire is selected for its "flexible aggression." While it is tough enough to remove metal burrs, its spring-like action ensures it polishes rather than gouges the main bore. For extremely sensitive materials, we recommend testing with a lower RPM first.
Q3: Can this tool be used in automated CNC machining centers?
A: Absolutely. The Lantern Brush is ideal for automated deburring cycles. It can be held in a standard collet or chuck. Its self-centering nature compensates for slight misalignments, making it a reliable choice for robotic or CNC integration.
Q4: How do I select the right size Lantern Brush for my application?
A: You should select a brush where the expanded "lantern" diameter is slightly larger than the diameter of the main bore. This ensures the necessary spring tension to press the wires against the cross-hole intersection.
Q5: Is this brush suitable for both through-holes and blind holes?
A: It is primarily designed for through-holes or holes where the intersection is accessible. For blind hole intersections, ensure there is enough clearance at the bottom of the hole for the lantern section to fully deploy.
