Router bit GRAPHITE 56H239 — single-piece cutting tool for woodworking

GRAPHITE 56H239 router bit is a single-piece cutting tool designed for woodworking routers. The shoulder milling cutter with bearing and sintered carbide cutting inserts provides stable performance when shaping, trimming and profiling wood and wood-based materials. With a 28.8 mm head diameter, 15.9 mm cutting height and an 8 mm shank, this router bit is suitable for tasks that require guided edge forming and decorative routing.

Advantages

The tool features hard-metal (HM) sintered carbide inserts on the head for wear resistance and consistent cutting quality. An integrated bearing simplifies guidance along workpiece edges, reducing the need for manual alignment while routing. The single-piece construction and compact shank make the cutter compatible with many standard routers that accept an 8 mm shank, providing reliable concentricity and vibration control during operation.

Suitable for

• Edge forming and profiling of solid wood and veneered panels
• Grooving and trimming in furniture making and cabinetry
• Decorative routing on MDF, chipboard and laminated surfaces
• DIY woodworking projects requiring guided cuts and consistent finishes

Key specifications

• Head diameter: 28.8 mm
• Cutting height: 15.9 mm
• Shank diameter: 8 mm
• Cutting material: sintered carbide (hard-metal) inserts
• Design: shoulder milling cutter with guide bearing
• Construction: single-piece router bit

How to use

Install the router bit into a compatible router collet that accepts an 8 mm shank and ensure the bit is securely tightened. Set the router speed appropriate for the material—lower speeds for laminated or chipboard materials and higher speeds for solid hardwoods within the router’s safe operating range. Guide the router along the workpiece using the integrated bearing to maintain a consistent profile; perform test cuts on scrap material to verify depth and feed rate before machining the final piece. Always switch off the router and wait for the cutter to stop before changing the bit or making adjustments.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust extraction when routing. Keep feeds steady and avoid excessive lateral force to prolong insert life. For best results, perform multiple shallow passes rather than a single deep cut, and ensure the bearing is clean and free of debris to maintain precise guidance.
