Spoilboard Surfacing Router Bits are built for fast, smooth, and precise flattening of CNC spoilboards, slabs, and large wood surfaces. With ultra-sharp carbide inserts and a durable body, they deliver clean cuts, extend tool life, and reduce sanding—perfect for keeping your CNC bed true and ready for accurate machining.

Excellent For Cutting:

  • MDF
  • Chipboard
  • Hardwood
  • Plastic
  • Plywood
  • Fiberboard
  • Softwood
  • Acrylic

TOOL SPECS: ½" shank, 2.5" cutting diameter, 4-wing carbide insert design (12×12×2.2 mm, 35° straight hole) for precise spoilboard surfacing and slab flattening.

FAST & EFFICIENT: Four ATS-coated inserts deliver fast, smooth cuts with superior heat and wear resistance.

LONG-LASTING VALUE: Includes 4 extra carbide inserts for extended use—rotate or replace inserts, not the entire bit, providing up to 2.5× tool life.

    Frequently Asked Questions

    Designed for leveling and cleaning the sacrificial spoilboard on CNC tables or router sleds. Wide diameter and multiple flutes ensure efficient flattening.

    A ½" shank offers greater rigidity and less vibration compared to thinner shanks.

    Replaceable insert bits (like Amana's with 4-sided knives) offer better longevity—cheaper over time versus replacing entire bits.

    Absolutely—surfacing bits perform flat surfacing much faster than small end mills, significantly reducing runtimes.

    Yes—but may still require sanding afterward for full smoothness.

    Community reports describe dust clouds on “cosmic scales”—strong dust collection is essential.

    Routers with 2¼ HP+, ½" collet, variable speed, and soft start are preferred. Examples: Porter-Cable 890, Bosch 1617 EVS.

    Some recommend raising spoilboard height or using a shorter sled to compensate.

    Yes—take shallow passes, reduce RPM, and keep bit moving to avoid burning.

    Use appropriate feed/fine passes and larger diameter bits; users reported no ridges on 5×8’ table using 2.5" bit.
