This 3 bit Round over and Bead router bit set is a staple for any woodworking shop. Great for edging, beading and/or molding applications, the CHWJW 13621, complete with 3 practical sizes is bound to come in handy all too often. Radius sizes are as follows:  1/4",  3/8",  1/2". Shanks are 1/2".  Note: All 3 bits feature 1/2" bearings. Included in this set is an extra 3/8" bearing and Allen wrench. You may use the 3/8" bearing to convert the cutting design of each bit from roundover to bead as needed. Enjoy!
