CCMT 09T304Nominal geometry

IC 9.525S 3.97R 0.4mm

Hole + one-face countersink · 1-face chipbreaker in base type. Outer envelope follows nominal IC, thickness and cutting-corner radius. Dashed circles are mounting symbols, not bore dimensions. Chipbreaker, edge preparation, tip construction and coating are not depicted. This is not a product photograph.

Separate scales for the three views. S is measured between the top and bottom reference planes. The side section shows the outer envelope only. Minor corners, bore/countersink dimensions, chipbreaker and edge preparation require the exact manufacturer drawing.

Where this radius sits

The CCMT 09T3 group in this directory has 4 entries, from 0.2 to 1.2 mm radius. This sits between the smallest and largest listed radii.

Confirm the part contour and tool compensation for 0.4 mm. A radius change does not establish surface finish, cutting data or holder compatibility.
