Fiberglass-impregnated materials are well known for their abrasiveness along with a tendency to fray or shred during machining along with heat created by the router bit.

Amana Tool’s response to these challenges is an extremely free-cutting, multi-edge Glass Reinforced Plastic (GRP) multi-flute tool that shears the material without shredding or imparting unnecessary heat.

Excellent for cutting:

Acrylonitrile-Butadiene-Styrene (ABS)

Carbon Fiber Reinforced Polymer (CFRP)

Composite Materials

Coroplast

Fiberglass

Fiberglass PCB Board

Fiber Reinforced Plastic (FRP)

High Impact Polystyrene (HIPS)

Low Density Polyethylene (LDPE)

Poly (methyl methacrylate) (PMMA)

Polycarbonate (Lexan)

Polyethylene Terephthalate Glycol-Modified (PETG / PET-G)

Thermoplastic Polyolefin (TPO)

Recommendation: Use the slowest suggested feed rates and the shortest bits necessary for cutting and routing Lexan.

Benefits of ZrN Coating

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

High resistance to wear

Extended tool life

Less friction & heat buildup

High resistance to wear
