Our favorite router bits for edge work
Infinity Cutting Tools
The Mega Flush-Trim compression bits, shown above, work great for pattern routing because the combination of upcut and downcut shearing cutters eliminates chip-out on both workpiece faces. They cut cleanly and smoothly and produce precise results. To maximize the compression advantage, center the bit height on the workpiece thickness, which might require a thicker template. We like the 11⁄2 "-diameter bits because they cut at a shallower angle than the 3⁄4 " bits, making them less "grabby" in reversing-grain shapes, such as circles. But if you can get only one bit, go for the 3⁄4 ×11⁄4 "—it's the one we use most often.
1⁄8 "-radius Traditional Bead
no. 80-102 (1⁄4 " shank), $34
We love this bit for table aprons because the bead and recess create a shadow that adds an eye-catching detail to an otherwise plain surface. You can also use this bit on the edge of adjacent faces of a workpiece to create a full-round bead that wraps around the corner.
11⁄2 " Rail & Stile Profile
no. 99-060, $64
This bit has multiple uses, a great attribute in a premium-priced bit. It works great for routing mating cope-and-stick profiles for door rails and stiles (use a slot-cutting bit [no. 99-062, $62] for the mating tenon and slot). But we use it most often to rout one-step edge profiles on small box lids and tabletops. The combination of a cove, round-over, and fillet provides a pleasing look scaled appropriately for smaller projects like these.
