Main Product Description
CMT 812.690.11B is one exact Item Code within the official 7/8/912B pattern-router-bit long series. The verified product row specifies a 3/4-inch cutting diameter, 1-1/2-inch cutting length, 3-1/4-inch overall length, and 1/2-inch shank.
CMT describes this family as double-fluted and carbide tipped. A bearing positioned above the cutting section supports top-template pattern routing while keeping the template and bearing reference visible during professional production work.
Official family guidance identifies cabinet and furniture pieces, signs, toys, and other template-generated projects. Final machine compatibility, tooling condition, workholding, guarding, and operating limits remain subject to the current CMT and equipment-manufacturer documentation.
