There's good reason for these cutters to be known as the Whiteside 'Flagship' bits. The 2+2 compression technology offers the ultimate edge finish, in particular laminated, veneered and plywood boards. This bit plows through tough end grains and rough woods leaving a smooth clean edge.
The "ULTIMATE" trim bits are perfect when working with templates or when using a router to flush trim matching wood surfaces. Whiteside's compression spiral design, along with a ball bearing guide, makes this bit easy to use in the router and produces a superior quality trimmed edge. The “ULTIMATE” trim series brings industrial engineered bits, previously manufactured for CNC machines, right into your shop.
The UDP9112 is a dedicated 'pattern' bit with shank mounted bearing.
