Hole + one-face countersink · 1-face chipbreaker in base type. Family proportions are illustrative; choose a specification for dimensions. Dashed circles are mounting symbols, not bore dimensions. Chipbreaker, edge preparation, tip construction and coating are not depicted. This is not a product photograph.
What distinguishes TCMT
Base configuration
Partly cylindrical hole with a single-side countersink; chipbreaker on one face.
Tolerance symbol M identifies a class. Use the applicable product drawing for acceptance limits.
These families share the outline letter T. Differences in clearance, tolerance and mounting remain relevant even when IC matches.

This family contains 6 size/thickness groups: 0602, 0902, 1102, 16T3, 2204, 2706. Compare radii within one group first; moving between groups can change the insert-seat envelope.
Shape and clearance do not identify workpiece material, coating, grade or cutting data. Use an exact catalogue example when available; otherwise confirm a maker’s full designation before ordering.
Aluminum Machining, PDF page 24 / printed page 22, exact designation row. Exact geometry row and IC20 availability mark in this catalogue. Cutting conditions require the applicable product data; no stock check.

Shape, clearance, configuration and nominal code tables only. No grade, usable-edge count, catalogue availability or acceptance tolerances inferred. Values labeled “code table” are interpretations of a designation, not measurements of a delivered product. Product-row values are reported separately, including differences in printed precision.
