Understand DCGT geometry and selection limits

DCGTFamily structure

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 DCGT

Base configuration

Partly cylindrical hole with a single-side countersink; chipbreaker on one face.

Tolerance symbol G identifies a class. Use the applicable product drawing for acceptance limits.

These families share the outline letter D. Differences in clearance, tolerance and mounting remain relevant even when IC matches.

Choose the comparison that matches your question

This family contains 5 size/thickness groups: 0702, 11T3, 1504, 1506, 1906. 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.

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.
