Two carbide tipped cutting edges, side cutting and plunging. For milling groove joints, e.g. teeth for corner joints or edges and grooves for longitudinal joints. Suitable for all kinds of solid wood, wooden and laminated materials and some plastics. Manual and mechanical feed. To extend service life we recommend pre-cutting with a straight bit (e.g. product line 3107). For producing tear free corner joints we recommend clamping a piece of wood under the workpiece.
