✔️ Single bit pack; 3-flute, 1/4 shank, 1/32 dia, 1/64 radius
These up-cut spiral CNC router bits deliver strong cutting performance and clean chip evacuation, making them well-suited for aluminum, brass, copper, acrylic and other plastics. They’re commonly used in 2D and 3D carving projects on CNC mills and routers to achieve precise pockets, slots, and profiles.
✅ Solid carbide construction for long cutting life and precision
✅ ZrN coating reduces heat and wear for extended tool life
✅ 3-flute design with 6.2° tapered ball tip for clean aluminum cuts
✅ Ideal for aluminum, brass, copper, acrylic, PVC, sign foam, and composites
✅ 1/4" shank fits standard CNC collets
💡 What is a ZrN coated up-cut CNC router bit used for in metal and plastic projects? Here’s a quick guide to help you pick the right bit.
- High-precision edge retention and heat resistance for longer tool life in aluminum, brass, copper
- Clean cuts in plastics like acrylic and PVC with reduced chip welding
- ZrN coating minimizes heat buildup and wear during prolonged routing
- Up-cut geometry improves chip evacuation and surface finish for 2D and 3D carvings
