Solid carbide flush trim bits significantly outperform standard flush trim router bits and excel where standard flush trim bits are lacking producing extremely smooth finished surfaces on some of the most demanding materials and applications. The solid carbide construction allows complex blade geometry and the welded steel tip accommodates a threaded lock nut for ease of use and reliability. These bits perform well on all types of woods including, plywood, MDF, solid woods, plastic laminates and non-ferrous metals.

This set includes 1 upcut and 1 downcut flush trim solid carbide router bit. The shanks and diameters are 1/4" with a 5/8" cutting length.

I made a cherry table and used it to cut mortises as well as groves the length of 6 planks. I made groves 1/2 inch deep for splines to locate the planks. The total distance would be roughly 55 feet of cutting. The bit was still sharp and cut 10 mortises 1 3/4 inch deep on the ends of the table.
I believe there's a possibility that those who broke the bits tried to cut the full depth in a single pass and at too great of a speed. To cut the full 1 3/4 inch mortise I made 3 passes, which is more or less standard procedure.
Using digital calipers I checked the floating tenons that fit the mortises and they measured .373 inches. .375 is 3/8 of an inch.
