Suitable for

• Template and pattern routing
• Edge trimming of laminates and veneers
• Professional woodworking and cabinetry
• Flush trimming wooden panels and components

When it may not be suitable

This router bit may not be suitable for handheld routing operations where stability cannot be assured, due to its substantial working length and cutting diameter. It is also not designed for plunge cutting into solid wood without a pre-drilled or pre-cut starting point.

Key specifications

• Carbide-tipped HM cutting edges
• Bottom bearing guided design
• 19 mm cutting diameter
• 50.8 mm working length
• 12 mm shank diameter

How to use

Securely insert the 12 mm shank into a compatible router collet, ensuring it is tightened to the manufacturer's recommended torque. Position your template or pattern onto the workpiece and align the bottom bearing of the router bit with the template edge. Always feed the router against the direction of the bit rotation to maintain control, and make multiple shallow passes if removing a large amount of material.

What to consider before purchase

• Verify that your router accepts a 12 mm shank diameter.
• Check that the 50.8 mm working length matches the thickness of the materials you intend to process.
• Ensure your router has sufficient power to handle a 19 mm cutting diameter efficiently.

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and ear protection, when operating a router. Regularly inspect the cutting edges and the bottom bearing for signs of wear or resin buildup to maintain optimal performance and safety.
