Car Audio Super Flush Trim Bit with 4 Bearings

These specialized flush trim router bits are designed to give the user a 1/32" offset - oversized or undersized - allowing you to follow a template and create pieces that are either 1/32" larger or 1/32" smaller than the original. Ideal for making speaker boxes where vinyl coverings and other components need additional space in order to fit together, these bits are precision made from the highest quality steel and micrograin carbide cutting edges and feature optimally sheared cutting edges to leave a perfectly finished surface. This high-quality construction means that you'll be able to make small rabbets and steps in a wide range of materials for longer periods of time between sharpenings than you would with conventional router bits.

The Super Flush Trim Bit (06-699) includes four stacked bearings to allow you to flush cut stacked or separated templates. With this bit you'll be able to make complicated shapes from varying template components in a single pass. Extra long cutter and aggressive shear-angled carbide cutting edges make for excellent chip ejection and superb cut quality.

  • C4 Micro-grain carbide tips for a long life and repeated sharpening
  • Silver PTFE coating reduces resin build-up for fast and easy cleaning
  • Aggresive shear-angled geometry for clean cuts without fraying or torn edges

Harper R. ★★★★★

I was skeptical about the four bearings making a difference, but swapping between oversized and undersized offsets without changing bits is a real time-saver. The carbide edge still looks sharp after cutting through several layers of MDF.

Hannah W. ★★★★★

The 1/32" offset is perfect for getting that tight, professional fit on my speaker baffles. Cut through the MDF smoothly with zero tear-out.

Samuel E. ★★★★★

The four bearings make this bit track perfectly along the template, and that 1/32" offset worked exactly as promised on my MDF ring. It's a real time-saver when you need a precise oversized cut without a second pass.
