Main Product Description
CMT 838.992.11 is one exact Item Code within the official 7/8/938 roundover-router-bit family. The verified row specifies a 1-inch profile radius, 1-5/16-inch cutting length, 2-1/2-inch cutting diameter, 3-13/64-inch overall length, and 1/2-inch shank.
CMT builds the family with FATIGUE-PROOF® steel bodies and carbide-tipped cutting edges. The bearing-guided geometry forms a clean large-radius edge profile for table and countertop edges, picture frames, furniture components, and compatible drop-leaf profile work.
The official row restricts this large-diameter variant to router-table use only and identifies bearing 791.003.00, bearing shield 990.423.00, screw 990.058.00, and hex key 991.057.00 as its matching service components.

Compatibility & Installation Notes
CMT 838.992.11 is for router-table use only; do not use it in a handheld router or select it by the 7/8/938 family heading alone. Confirm a clean compatible 1/2-inch collet, suitable fence and guarding, secure workholding, adequate clearance for the 2-1/2-inch diameter, correct bearing assembly, and all applicable router-table and tool operating limits before use.

Accurate Item Code selection, router-table compatibility, collet fit, bearing condition, cutter clearance, guarding, workholding, and equipment limits are essential to consistent large-radius edge profiling.
