These entries are kept together with their family comparisons. Their dimensions are code-table interpretations; no exact manufacturer product is established by these entries.
Designation reference
VCMT 160402
Inscribed circle
9.525 mm
Thickness
4.76 mm
Corner radius
0.2 mm
radius: 0.4 → 0.2 mm. The nominal IC and thickness are unchanged. Matching nominal envelope does not confirm holder compatibility.
The linked product has a different radius. It is a comparison, not a replacement recommendation. Obtain a full manufacturer designation for VCMT 160402 before ordering.
Designation reference
VCMT 160412
Inscribed circle
9.525 mm
Thickness
4.76 mm
Corner radius
1.2 mm
radius: 0.8 → 1.2 mm. The nominal IC and thickness are unchanged. Matching nominal envelope does not confirm holder compatibility.
The linked product has a different radius. It is a comparison, not a replacement recommendation. Obtain a full manufacturer designation for VCMT 160412 before ordering.
Designation reference
VCMT 160416
Inscribed circle
9.525 mm
Thickness
4.76 mm
Corner radius
1.6 mm
radius: 0.8 → 1.6 mm. The nominal IC and thickness are unchanged. Matching nominal envelope does not confirm holder compatibility.
The linked product has a different radius. It is a comparison, not a replacement recommendation. Obtain a full manufacturer designation for VCMT 160416 before ordering.
Understand VCMT geometry and selection limits
VCMTFamily 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 VCMT
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 V. Differences in clearance, tolerance and mounting remain relevant even when IC matches.
Choose the comparison that matches your question
This family contains 2 size/thickness groups: 1103, 1604. 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 22 / printed page 20, 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.
