Amana tool 49646 Carbide Tipped Bead Rail Cutter 3/8 R x 1-1/2 D x 15/32 CH x 23/64 R x 1/4 Inch SHK w/ Upper Bal Bearing Router Bit

Also known as stile and post router bits. Unique series of matching stile & rail cutters with 1/4" shanks. Many applications, such as doors, windows, moldings, etc. can be performed. Tenon & groove must be cut separately. Our Carbide-Tipped Profile Cutters are a unique and versatile series that can be used for general profile routing, glass doors and windows, as well as stile and rail work. (The panel groove and stub tenon must be cut separately.) The inverted hand cutters will produce copes that nest perfectly into the profiles cut by the matching “regular” bits. In addition, the inverted head allows you to profile edges that are out of the reach of regular profile bits. These 1/4" shank bits will fit any router. All are equipped with ball bearing guides, either on the tip or on the shank.
