Router bit GRAPHITE 56H231 — single-piece cutting tool for woodworking

GRAPHITE 56H231 router bit is a single-piece shoulder milling cutter with an integrated bearing, designed for precise edge profiling and trimming of wood and wood-based materials. The cutting head uses sintered carbide inserts to provide wear resistance and clean cuts while the bearing guides the tool along workpiece edges or templates. With a working diameter of 39.3 mm, cutting height of 15.9 mm and an 8 mm shank, this cutter is compatible with handheld and table routers that accept 8 mm tool shanks.

Advantages

The tool’s sintered carbide cutting inserts deliver longer life and consistent cutting performance compared with standard high-speed steel tips. The built-in bearing simplifies routing by allowing accurate guidance along edges and templates without the need for separate guide bushes. The single-piece construction ensures stable concentricity and reduces vibration during operation, improving surface finish on edges and grooves.

Suitable for

• Edge profiling and decorative shoulder milling on solid wood
• Trimming and finishing of chipboard, MDF and veneered panels
• Routing along templates and guides for repeatable profiles
• Cutting grooves and rebates where a guided bearing is required

Key specifications

• Cutting diameter: 39.3 mm
• Cutting height: 15.9 mm
• Shank diameter: 8 mm
• Cutting material: sintered carbide inserts
• Tool type: shoulder milling cutter with bearing
• Construction: single-piece cutter body

How to use

Install the router bit into the router collet designed for an 8 mm shank and tighten according to the router manufacturer’s torque instructions. Set the router speed and feed rate appropriate to the workpiece material; use lower speeds for hard materials and higher feeds for softer wood. Guide the cutter along the workpiece edge or template with steady, even passes, taking multiple shallow cuts rather than a single deep cut to achieve a smooth finish and reduce stress on the tool. Ensure the bearing runs against the template or edge to maintain consistent profiles.

Usage recommendations

Wear eye and hearing protection, and use dust extraction when routing. For best results, perform a test cut on scrap material to confirm depth and profile before working on the final piece. Replace or sharpen carbide inserts when chipping or burning appears to maintain cut quality.
