Core Substrate & Application Profiles
Thanks to its uniform 6 mm thickness, this bit delivers maximum torque transfer and high resistance to snapping. It is the premier choice for deep routing, profiling, and 3D carving on thick rigid substrates up to 22 mm:
Aluminum & Metal Composites (ACM): Excels at high-speed routing of heavy aluminum skins and composite core panels.
Thick Plastics & PVC: Ideal for processing dense engineering plastics, expanding PVC sheets, and polycarbonates without material welding.
Hardwoods, Plywood, & MDF: Easily slices through structural timber panels or dimensional sign-making lumber.

Operational Advantages & Rules
The "BAL" High-Speed Stability: Because it is dynamically balanced, it spins smoothly inside the high-frequency router head without micro-chatter. This eliminates surface edge lines, guarantees square walls, and prevents early failure of expensive spindle bearings.
Deep Flight Chip Evacuation: The single-flute up-cut spiral design acts as an Archimedes screw, aggressively hoisting massive amounts of debris upward out of deep 22 mm slots. This keeps heat build-up low and prevents re-cutting of debris. 
Step-Down Adjustments: Even though the bit has a robust 6 mm core, clearing dense materials like aluminum or hardwood at the full 22 mm depth in one pass can overload the spindle. Utilize a step-down pass strategy in your software to distribute the structural tool load.
Collet Cleanliness: Requires a standard 6 mm collet. Ensure the internal clamping slats of the collet are entirely free of fine dust before tightening to keep tool runout at zero.
