Fisch Black Shark Forstner Bit for Neck Ferrules
Drill flat-bottom holes with smooth, clean edges. Ideal for flush-fit Neck Mounting Ferrule installation (after all, there's no neck plate to hide ragged holes).
The fluted design generates less heat, for longer life and efficient wood chip discharge. Black Shark bits are sharper and cut faster than other Forstner bits.
Choose your bit based on your finish
5/8" bit (#103527) will create a slightly bigger hole than our Neck Attachment Ferrules, to accommodate finish overspray build-up in the drilled holes.
15mm bit (#103528) cuts a smaller hole for a tighter fit—best for oil finishes or thin, vintage-style finishes where build-up is not a factor.
Dimensions:
Bit diameter: choose 5/8" or 15mm
Shank diameter: 5/16" (8mm)
Overall length: 3-1/2" (90mm)
Forged steel.
