-
Double-flute design enhances chip evacuation and yields smoother edge finishes, helping you achieve cleaner cuts with less tear-out in wood and composite materials.
-
Compact 3/8 in diameter is ideal for precise, narrow slots, trimming tasks, and guided straight cuts, while the 1/2 in shank ensures compatibility with a wide range of routers.
-
Compact length and reach (2-7/8 in overall, 1-1/4 in cutting length) provide versatility for surface-trimming, mortising prep, and shallow dados without excessive tool engagement.
-
Convenient packaging in a clamshell makes storage and display simple, so you can grab the right bit quickly for your project bench or job site.
Ideal use cases
- Precision straight cuts in hardwoods, softwoods, plywood, MDF, and other composites
- Edge trimming and alignment tasks where a clean, flat finish is essential
- Guided routing on cabinetry, furniture, and hobby projects that require repeatable, accurate passes
- Setup-heavy tasks where a reliable, repeatable cut helps reduce sanding and rework
Tips for best results
- Use a router with a compatible 1/2 in shank and appropriate speed for carbide bits to maximize life and finish quality.
- Feed steadily to maintain a smooth cut and minimize tear-out. Let the bit do the work—avoid forcing it through material.
- Maintain good workpiece support to prevent chipping at the edges and achieve true, square cuts.
- Pair with guides or templates for precise, repeatable straight routes across multiple pieces.
