Router bit GRAPHITE 56H204 — single pack, replacement cutter for woodworking routers

GRAPHITE 56H204 router bit is a double-ended end milling cutter designed as a single replacement cutter for woodworking routers and trimming tools. Constructed with a 12 mm shank and a 12 mm diameter working head, this cutter has a working height of 25 mm and is intended for precision machining of wood, PVC, chipboard and similar panel materials. The head is fitted with sintered carbide cutting inserts that provide consistent cutting performance and a high-quality surface finish when used in compatible routers.

Advantages

The cutter features sintered carbide inserts on the head for enhanced wear resistance and long cutting life compared with standard high-speed-steel tools. A 12 mm shank ensures stable clamping in compatible collets, reducing runout and vibration during operation. The double-ended design provides two usable cutting edges in one tool, enabling economical replacement and extended service intervals. The combination of a compact 12 mm diameter and 25 mm working height allows for a variety of routing tasks while maintaining control and precision.

Suitable for

• Edge profiling and trimming of wooden boards and laminated panels
• Slotting and groove cutting in wood, chipboard and MDF
• Trimming PVC edging and synthetic surfaces
• Replacement or spare cutter for compatible handheld and table routers

Key specifications

• Tool type: double-ended end milling cutter for routers

• Working head diameter: 12 mm
• Working height: 25 mm
• Cutting material: sintered carbide inserts
• Suitable materials: wood, PVC, chipboard, MDF and similar panel materials

How to use

Install the router bit into the router collet, ensuring the shank is fully inserted and the cutter is securely tightened according to the router manufacturer's instructions. Verify the router speed and feed rate are appropriate for the material being machined; higher speeds are generally used with carbide cutters, but settings should match material thickness and density. Perform a test cut on a scrap piece to confirm depth and alignment, then proceed with steady, controlled passes, avoiding excessive feed force. Replace or reverse the double-ended head when the active edge shows wear to maintain cutting quality.

Usage recommendations

Use appropriate personal protective equipment, including eye and hearing protection, and ensure workpieces are properly clamped. For best surface finish, take multiple shallow passes rather than a single deep cut and keep cutting edges clean from resin or adhesive buildup. Regularly inspect the carbide inserts for damage and replace the cutter if inserts are chipped or excessively worn.
