Overview

The Byrne V-Groove Blade Set Pro for Festool Replacement (model BE-DT20, Byrne item 180857) is a replacement insert set for the Byrne V-Groove Blade Set Pro. This is a set of drywall V-groove cutter blades designed for restoring cutting performance when the original inserts wear out.

The V-Groove cutter disc uses square and triangular inserts to cut a 90-degree groove in plasterboard and drywall. Gypsum is abrasive, and after enough linear feet the edges dull and the groove starts to tear the face paper. That is when you rotate each insert to a new edge. When every edge has been used, this set puts a full set of fresh inserts on the disc.

The set contains two square blades and four triangle blades made from alloy steel, packed in a case. The inserts install with the Torx drivers that come with the V-Groove Blade Set Pro.

Who should buy this: anyone running the Byrne V-Groove Blade Set Pro (VT-55-CN-90V) regularly. Keep a set on hand so a dull cutter never stops a board-hanging day.

Pro Tip

Rotate all the inserts at the same time, not one at a time. Mixing a sharp edge with dull ones leaves a ragged groove and makes the fold uneven.
