Cut rabbets the size you need without any fuss using this great bit set. Using a set of 15 interchangeable bearings and special collars, plus the standard Rabbet bit bearing, this bit cuts rabbets in 17 different widths. Shear cut carbide design reduces chipping for an extra smooth surface. Rabbet collars slip over the supplied bearings to change rabbet depth. Note that the collars fit over 1/2" OD bearings only. Collar set GR5-1707 provides rabbet depths for today’s undersize plywood.
