Fisch Forstner Bit for Neck Ferrules

Drill flat-bottom holes with smooth, clean edges. Ideal for flush-fit neck attachment ferrule installation (after all, there's no neck plate to hide ragged holes).

Patented "Wave Cutter" flutes generate less heat, for longer life and efficient wood chip discharge.

Choose your bit based on your finish.

5/8" bit (#4496) will create a slightly bigger hole than our Neck Attachment Ferrules, to accommodate finish overspray build-up in the drilled holes.

15mm bit (#4499) cuts a smaller hole for a tighter fit — best for oil finishes or thin, vintage-style finishes where build-up is not a factor.

Both bits are forged steel with 8mm (5/16") shank.
