Router Bits with Carbide Inserts
Router bits with carbide inserts can save you up to 60% of time and money compared to conventional milling cutters. Because when the inserts are worn or chipped, you only need to replace the inserts instead of the entire tool.

Unique Dual Bearing Design
This router bit features a top and bottom dual bearing setup. This design enhances stability, improves planing accuracy, and provides better balance when the machine is running at high speeds, making cutting more efficient without compromising performance.
The spoil board surfacing router bit is ideal for wood flattening, bottom cleaning, rabbeting, resurfacing, and also for trimming, slotting, and grooving. The replacement carbide insert makes the router bit more economical.
