Router bit Festool groove cutter 490964, length 60 mm, working length 20 mm

Festool groove cutter 490964 is a single-piece router bit designed for precise slotting and groove cutting in solid wood and wood-based panels. With an overall length of 60 mm and a working length of 20 mm, this cutter is intended for use with compatible routers and guide systems to produce clean dados, joints and trimming operations in furniture and cabinetmaking.

Advantages

The bit features a soldered standard tungsten carbide cutting edge that extends service life even during plunge cutting. Optimised cutter geometry, a stable shaft and factory-sharp cutting edges contribute to consistent, flawless surface finishes and accurate groove dimensions. The one-piece construction reduces vibration and increases reliability when routing repetitive or precise joinery.

Suitable for

• Cutting grooves and dados in solid wood
• Routing slots in plywood, MDF and chipboard
• Joinery tasks in furniture and cabinetmaking
• Trimming and edge work with guide systems

Key specifications

• Tool type: groove cutter / router bit
• Overall length: 60 mm
• Working (cutting) length: 20 mm
• Material of cutting edge: tungsten carbide (soldered)
• Construction: single-piece bit with solid shaft for stability

How to use

Install the router bit in a compatible router collet and secure it according to the router manufacturer's instructions. Set cutting depth to achieve the required groove dimensions, and use an appropriate guide or fence to maintain a straight path. Feed the workpiece at a steady, controlled rate—avoid dwelling in one spot to prevent burn marks. For plunge cuts, ensure the router is held firmly and the plunge action is smooth to protect the soldered carbide edge.

Usage recommendations

Use appropriate router speeds for the material being cut: higher speeds for harder woods and lower speeds for particleboard or laminated panels. Support the workpiece and use dust extraction when possible to prolong cutter life and maintain a clean working environment. Inspect the cutting edge regularly and replace the bit when wear affects cut quality.
