Infinity Tools 1/4インチシャンク 真鍮ガイド付き丸面ルータービット

Used these on a dozen flight trays for a buddy's brewery and the brass guide bearing held up perfectly through all those passes. The 1/4" shank gave me plenty of control for routing those intricate shapes without any chatter. Just wish it came in a slightly larger radius for thicker boards but that'

The bearing rides so smoothly that even the tricky curved cuts on those flight trays came out with zero tear-out, and the brass guide held up across all 100 pieces without a hint of wear. I’ve already reached for it on three other projects since, and it’s still cutting just as crisp as the first day

The bearing glides along the edge so smoothly that I barely had to sand the finished trays—the roundover came out glass-smooth on every single one of the 100 boards. Even after a full day of routing, the bit stayed cool and sharp.
