    Hi Mike! The 91-100 set contains 13 bits, all with ½” shanks. The largest bit in the set has a 1-3/4” cutting diameter. We recommend checking with the manual that came with your router to be sure it will accept bits with ½” shank and with cutting dimensions of that size.

      Does the 13-bit set come with multiple sizes of bearings for the rabbeting bit or others?

      Answer This Question

      Hi Leslie! The Rabbeting bit packed in the 91-100 set includes one bearing, which is ½” diameter and produces a cut depth of 3/8”. The bit can be purchased with a set of 6 additional bearings. To check it out, just search homedepot.com for Product #32-524.

                  Great Bits
                  Bought Diablo bits, but they are actually Freud bits. These are considered top of the line bits! the Home Depot shipped them free and right to my door within a couple of days. Very Happy with my choice to buy from them.

                    Less than pleased
                    I primarily have used the straight bits out of this set. The reason for the 2 star rating is the 1/4 straight bit doesn't cut a full 1/4 channel. Perhaps it is the wood I use, but for the price I paid for the set, my expectation is that the 1/4" bit would allow a 1/4" or less thick sheet of plywood to fit in the channel it creates. Not so.

                      Case should be improved
                      Can be a challenge to get out of the case but the bits themselves work flawlessly

                        These bits are perfect for cutting an slightly undersized dado to hold the undersized plywood that goes in the dado.

                        My mistake, I ordered 1/2" instead of 1/4". What a great set that I had to send back. I went and bought 3 individual bits at the local hardware store for almost the same price as this set of 13.

                        The 3/4” bit plowed a very clean dado in one pass into a sheet of BC plywood. Very impressed. I do wish that the bits were sold separately. I don’t foresee needing the other three bits in the set.
