Overview

Festool Plasterboard V-Groove Cutter HW S8 D12,5/45° At a Glance: Single-edged, carbide-tipped plasterboard cutter with a 45° profile, 12.5 mm cutting diameter, 14 mm cutting length and 8 mm shank. Designed for manually guided router applications. Prepare accurate folds in plasterboard with the Festool HW S8 D12,5/45° V-groove cutter. Its specialised geometry removes material along a controlled routing line while allowing the opposite paper facing to remain intact. This retained facing acts as a hinge when forming the corner, helping you create shaped plasterboard components from a single panel. Carbide cutting material provides wear resistance, making this a practical accessory for drywall installers, interior fitters and renovation specialists producing neatly aligned folds and angled details. What is plasterboard V-grooving? V-grooving removes a shaped channel from one side of a plasterboard sheet. When the depth is correctly set, the paper on the opposite face remains uncut, allowing the board to fold along the routed line. Accurate depth control and straight guidance are essential to the result.
