Product Material Composition:

• Filament Material: Twisted alloy steel wire or stainless steel wire – woven into an expandable lantern-shaped cage; stainless steel option for non-marring action on aluminum/copper alloys; alloy steel option for maximum cutting force on hard burrs

• Shank Material: Brass rod – provides excellent rigidity for CNC machining centers, drill presses, and automated equipment; resists bending during deep-hole operations

Product Features and Applications:

Our Lantern-Style Cross Hole Deburring Brush (commonly known as cross hole brush, lantern tube brush, or cross-hole deburring tool) features a unique expandable lantern-shaped wire cage woven from twisted alloy steel or stainless steel wire. The brush relies on the elastic expansion of the wire cage to radially expand within intersecting holes, T-junctions, Y-holes, deep blind holes, and stepped bores – effectively deburring the intersection points where standard straight shank brushes cannot reach .

Key Features:

• Expandable Lantern Cage Design – radially expands to contact the sharp edges of intersecting bores, effectively knocking down rolled burrs at cross-hole intersections

• Superior Wire Flexibility – resilient steel wire construction allows insertion into deep, narrow oil passages and curved holes with minimal risk of wire breakage or jamming

• Rigid Brass Shank – provides excellent rigidity for CNC machining centers, drill presses, and automated deburring cells; ideal for high-volume production environments 

• Dual Material Options – stainless steel wire for non-marring action on aluminum and copper alloys; alloy steel wire for maximum cutting force on hardened burrs

• Flexible Access to Complex Geometries – designed to navigate bent tubes, long-radius bends, and serpentine passages that rigid tools cannot access 

• Self-Centering Action – the lantern geometry naturally centers itself within the bore, providing uniform 360-degree deburring pressure and preventing uneven material removal 

Application Fields:

• Hydraulic Valve Blocks and Integrated Manifolds – deburring cross-drilled oil passages, intersecting galleries, and internal flow paths where burrs can cause valve sticking or seal damage 

• Engine Cylinder Blocks and Cylinder Heads – cleaning oil galleries, coolant passages, and intersecting holes in automotive and heavy-duty engine manufacturing 

• Injection Molding and Die Casting Molds – cleaning cooling water channels, hot runner systems, and complex mold cavities

• Precision Machining – deburring special-shaped deep holes, stepped bores, and angled through-holes in complex machined components

• Pneumatic Components and Solenoid Valves – internal cleaning of valve bodies, air circuits, and fluid power components

• Heat Exchanger and Pipe Cleaning – internal surface treatment of hydraulic tubing, copper tube heat exchangers, and fluid pipe bundles

• New Energy Vehicle Component Finishing – deburring battery cooling plates, motor housings, and precision structural components

• General CNC Post-Processing – standard deburring auxiliary operation for machined parts with intersecting holes

Why Choose a Lantern-Style Brush for Cross Hole Deburring?
Intersecting holes present a unique deburring challenge. The intersection of two bores creates a sharp edge that standard straight brushes or bristle tools cannot effectively reach. Our lantern-style brush is specifically engineered to address this challenge through its expandable wire cage . The brush compresses during insertion, then springs open at the intersection, allowing the wire tips to engage the burr directly at the precise point of intersection. This self-centering, self-compensating action ensures consistent, repeatable deburring results – making it the standard tool for hydraulic valve and engine block finishing operations .
