Router bit GRAPHITE 56H214 — 1 pc, woodworking cutter for routing

GRAPHITE 56H214 — long U type groove cutter supplied as 1 piece. This woodworking router bit is designed for precision machining of wood, wood-based materials, PVC and similar panels in handheld or table routers. The cutter head uses sintered carbide (HM) cutting inserts for increased wear resistance and consistent cutting performance. Working part dimensions are 25.4 mm diameter and 22.5 mm cutting height, with an 8 mm shank suitable for most light and medium-duty routers.

Advantages

The long U profile and replaceable HM inserts provide stable groove geometry and longer service life compared with standard high-speed steel cutters. The 8 mm shank ensures compatibility with common collet sizes, and the carbide tips maintain sharpness for cleaner edges and reduced tear-out on wood and laminates. The single-piece supply makes it convenient to assign this cutter to a dedicated task or machine.

Suitable for

• Routing U-shaped grooves in solid wood and softwood
• Machining grooves and channels in chipboard and MDF
• Creating decorative or functional channels in laminated panels and PVC
• Edge profiling and trimming operations on door panels and furniture parts

Key specifications

• Cutter type: long U groove (U-type profile)
• Cutting material: sintered carbide (HM) inserts
• Working diameter: 25.4 mm
• Cutting height: 22.5 mm
• Shank diameter: 8 mm
• Pack quantity: 1 piece

How to use

Install the router bit in the router collet and tighten securely, ensuring the 8 mm shank is inserted to the recommended depth. Set the router speed according to material and bit diameter — moderate speeds for laminate and higher speeds for softwoods, while avoiding excessive rpm to prolong insert life. Make controlled passes and remove small amounts of material per pass to reduce stress on the inserts and obtain a clean U-shaped groove. Always let the cutter reach full speed before contacting the workpiece and feed against the rotation for safe, controlled cutting.

Usage recommendations

Use appropriate personal protective equipment (eye and hearing protection, dust extraction). For best results, stabilize panels on a flat work surface, clamp securely, and perform test cuts on scrap material to set depth and feed rate. Replace or rotate carbide inserts if signs of chipping or burning appear. Avoid cutting highly abrasive materials that can accelerate wear on the sintered carbide tips.
