Key Features & Benefits
- Medium-Scale Fine Point Profile — the 13.70mm A dimension and R6.35mm radius produce a more prominent bead groove than the TBF 4, suited to standard cabinet and panel door face work.
- Fine Point Base — the sharp point at the base gives a crisp, refined profile finish, preferred over flat-base beading when a delicate detail appearance is important.
- No Bearing — Fence or Template — use with a router table fence for consistent, repeatable groove placement.
- 2-Flute Carbide-Tipped — handles long production runs in hardwood and MDF.
When to Use This Bit
Use the TBF 8 for panel door face grooving and surface beading where a medium-scale fine point profile is needed. Larger and more prominent than the TBF 4 but still with the crisp fine-point base. For a flat-base version at the same size, use TBB 8. For edge beading with a ball bearing guide, see the TB series beading bits.
Pro Tip: Mark your fence position clearly before starting a batch run of panel doors — consistent fence distance from the bit guarantees matching grooves across all components without re-measuring.
