Main Product Description
CMT 815.127.11 is one exact Item Code within the official 7/8/915 family of 90° V-grooving router bits. The verified row specifies a 1/2-inch cutting diameter, 1/2-inch cutting length, 1/4-inch tip depth, 1-3/4-inch overall length, 1/4-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 12.7 mm cutting diameter, 12.7 mm cutting length, 6.35 mm tip depth, 44.5 mm overall length, and 6.35 mm shank. Correct machine compatibility, collet fit, guarding, workholding, and cutter clearance remain essential.
