Main Product Description
CMT 815.660.11 is one exact Item Code within the official 7/8/915 family of 90° V-grooving router bits. The verified row specifies a 5/8-inch cutting diameter, 1/2-inch cutting length, 5/16-inch tip depth, 2-1/2-inch overall length, 1/2-inch shank, two cutting edges, HW active cutting material, and right-hand rotation.
CMT describes the family as double-cutting-edge tooling for clean cuts in panels and drawer fronts, as well as chamfering and lettering. The 90° included angle creates a V groove and also allows the same profile to produce a 45° edge chamfer.
The 2026 CMT router-bit catalog corroborates the exact variant at 16 mm cutting diameter, 12.7 mm cutting length, 8 mm tip depth, 63.5 mm overall length, and 12.7 mm shank. Correct machine compatibility, collet fit, guarding, workholding, and cutter clearance remain essential.
