Specify the complete ordering code, including nose radius and geometry suffix, when requesting a size.
What do 060204, 09T304 and 120408 indicate?
They identify different insert sizes and corner radii. In the supplied table, CCMT060204 has IC 6.35 mm, S 2.38 mm and RE 0.4 mm; CCMT09T304 has IC 9.525 mm, S 3.97 mm and RE 0.4 mm; CCMT120408 has IC 12.7 mm, S 4.76 mm and RE 0.8 mm. Check the full dimensions and the holder specification before choosing a replacement.
Are these inserts suitable for both external finishing and internal boring?
A suitable CCMT insert may be used for either operation when paired with a compatible turning holder or boring bar. Check holder orientation, insert seat and clamping, boring-bar clearance and overhang, and the selected geometry and grade for the workpiece. The dimensions alone do not establish suitability for every setup.
How should I choose the nose radius?
The listed RE values range from 0.2 to 1.2 mm, depending on the ordering code. Select the radius in relation to the required profile and surface finish, feed, cutting allowance and setup rigidity. For a boring operation, also check tool clearance and vibration before selecting a larger radius.
What is the difference between MM, FP, GP and KM?
These suffixes identify different geometries in the supplied product charts. Their exact chipbreaker design and application limits are not defined by the dimensional table. Provide the workpiece material, operation and target finish so the geometry and grade can be confirmed for the complete ordering code.
Are the cermet and CCGT/CCGX entries in the images part of this product?
No. The original images also show CCMT 5PL and TP cermet entries and separate CCGT/CCGX codes. The specification table for this page covers the listed carbide CCMT MM, FP, GP and KM entries. Confirm the material and complete code if you need one of the other insert types.
