This flush trim router bit was designed to eject chips up for clean cuts in aluminum and ACM materials. Perfect for routing aluminum using a template. Features a special carbide grade to perform high-quality cuts in aluminum.

Excellent For:

• Aluminum
• Aluminum Composite Materials (ACM)
• MDF
• Wood

• Creates a harder and tougher cutting edge allows for a prolonged cutting edge life and helps to prevent the build-up of material in the flutes while cutting
• Have the tendency to run/spin much faster than an uncoated tool
• Optimized flute geometry and low Total Indicated Runout (TIR) guarantees clean cuts, essentially eliminates sanding and reduces chatter (where the machine or work piece vibrates) under high chip loads (when used with low TIR spindles)
• High flute volume supports high feed rates and chip loads
• High aspect ratio for single pass deep-reach cutting
• Flute geometry optimized for cutting sign foam, sign board, hardwoods, thermoplastics and phenolic composites
