Straight Router Bits

The simplest and most affordable alternative is to use a standard straight router bit. These are readily available at any hardware store for less than $20.


  • Extremely inexpensive
  • Easy to find locally
  • Create straight edges and holes


  • Not optimized for Trex’s dense material
  • Higher risk of chipping, splintering, and overheating
  • Slow feed rate required
  • Shorter lifespan than trex-specific bits

While straight router bits will get the job done, you’ll need to take light passes and move the router slowly to avoid potential issues with Trex.

The unsupported carbide tips may chip away, so these bits don’t last nearly as long. For occasional Trex projects these offer a budget solution, but frequent Trex users will want something more optimized.

Carbide Tipped Router Bits

Carbide tipped router bits provide a step up from basic straight bits. They have brazed carbide cutting tips at the top, making them much harder and more wear resistant than standard high-speed steel bits.

  • Still reasonably affordable at $25-40


  • Not designed for dense composite materials
  • Requires slow feed rates on Trex
  • Higher potential for overheating

With their enhanced carbide tips, these bits fare better on Trex than basic options. However, they are still general purpose bits not specifically made for composite decking.

Care must be taken to cut slowly and avoid buildup of heat. For DIYers doing occasional Trex work, they offer a nice middle ground before investing in pricey tooling. Those working with Trex frequently will still want an optimized bit.

Plywood Cutting Router Bits

Router bits made for cutting plywood are also sometimes used for Trex. The large carbide tips and specialized geometries are designed to cut dense manmade sheets smoothly and cleanly.


  • Aggressive cutting geometrybetter suited for composites
  • Large carbide cutters resist chipping
