Insert-to-Cutter Match

Match Each MPHT Insert to the Correct SMP Platform

The cutter catalogue links each insert size to one SMP suffix. Use the suffix at the end of the cutter model to identify the correct insert, screw and wrench.

Platform 06Uses MPHT060304-DM with SMP bodies ending in -06.

Platform 08Uses MPHT080305-DM with SMP bodies ending in -08.

Platform 12Uses MPHT120408-DM with SMP bodies ending in -12.

DM GeometryRetain the complete suffix because geometry changes can affect cutting behavior and seat contact.

SMP is a snap-on type side and three-edge milling cutter family. MPHT should be selected by platform, cutter width and bore—not as a generic face-milling insert.

Cutter Compatibility

SMP Snap-On Type Cutter Range

The supplied cutter catalogue lists SMP bodies from Ø80 to Ø200. Select by cutter diameter, width, bore, teeth count and the final platform suffix.

06 PlatformØ80–125 bodies using MPHT060304-DM, M2.5×6.5 screws and T8 wrench.

08 PlatformØ125–160 bodies using MPHT080305-DM, M3×8 screws and T8 wrench.

12 PlatformØ160–200 bodies using MPHT120408-DM, M5×12 screws and T20 wrench.

Example: SMP-160x18-K40-12T-12 means Ø160 cutter diameter, 18 mm width, K40 bore, 12 teeth and the MPHT12 platform.
