Review on 🔪 Ultimate Precision with Bestgle Straight Carbide Woodworking Diameter by John Mahfood

I needed to cut a 3/4" x 3/4" groove in 2x4 mahogany. I cut a 3/8" x 3/4" slot with a cutter, which I then finished with a new 3/4" cutter. The 3/4" cutter continued to pull out 2- to 3-inch Shavings out instead of regular sawdust. The new router bit did the job but later became dull. The problem may have arisen because I made a 3/8" cut. Great value for the money but I doubt how long they stay sharp.
