Key Features & Benefits
- Fine Point Bead Profile — the sharp 1mm base point creates a crisp, precise groove suited to fine detail work where a flat bottom would look too heavy.
- Compact Size (A 7.37mm) — the small cutting diameter produces a delicate bead line, proportionally correct for narrow grooves on small panel door inserts and decorative inlay work.
- No Bearing — Fence or Template Use — position precisely against a router table fence for straight runs, or use with a clamped template guide for face forming.
- 2-Flute Carbide-Tipped — long service life in hardwood and MDF.
When to Use This Bit
Use the TBF 4 for fine bead grooves on panel door faces, cabinet drawer fronts, and decorative surface patterns where a crisp, narrow point profile is required. For a larger fine-point bead, choose TBF 8. For a standard (flat-base) bead profile, use the TBB 4 or TBB 8 instead.
Pro Tip: Fine point bits are most vulnerable at the tip. Always run at full router speed (18,000–22,000 RPM) with a steady, even feed rate. Avoid dwelling in the cut, as this generates heat at the point and can cause tip chipping.
