Description
51521, Amana Solid Carbide Glass Reinforced Plastic Cutting 1/8 Dia x 1/2 x 1/4 Shank Up-Cut ZrN Coated Spiral Bits
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:
- Fiberglass
- Composite Materials
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
