Walter Tools M4000
Walter M4000 is a milling platform organized around system inserts used across application-specific cutter bodies. The M4003 face-milling branch uses positive square inserts with four cutting edges, while body diameter, connection, insert size, pitch, and cutting depth remain designation specific.
Product system overview
Walter M4000 is a milling platform organized around system inserts used across application-specific cutter bodies. The M4003 face-milling branch uses positive square inserts with four cutting edges, while body diameter, connection, insert size, pitch, and cutting depth remain designation specific.
Industries and applications
- M4003 face milling for roughing, semi-finishing, and finishing.
- Applications seeking one system-insert strategy across compatible M4000 cutter bodies.
- Face milling where positive geometry and optional cermet finishing inserts fit the material and finish target.
Technical and quote details
- M4003 uses a 45-degree approach angle and four cutting edges per square insert.
- Walter catalog data separates SD..09T3 and SD..1204 insert sizes with different maximum depths of cut.
- Bodies are published with cylindrical shank and shell-mill/arbor configurations across a broad diameter range.
- The catalog includes circumference-sintered and precision-ground insert strategies and multiple grades.
- Complete designation, insert size, grade, connection, tooth count, and any BOW variant must be retained.

Selection notes
Store the exact body designation, insert size and designation, grade, tooth count, connection, cutting depth, and wiper configuration.
Use the current Walter indexable-milling catalog and online catalog for exact compatible components.
Variables to validate
- M4000 is a platform label and does not establish body-to-insert compatibility.
- SD..09T3 and SD..1204 insert systems have different bodies and cutting-depth ranges.
- Cermet and carbide grades, wiper strategies, insert geometry, pitch, and material fit must be validated per item.
