Jump to all APMT1604 modelsWhat Is an APMT Milling Insert?
APMT is a positive parallelogram-shaped indexable milling insert commonly used in shoulder, side, pocket and selected face milling cutter systems.
The four letters identify the basic ISO-style form, clearance, tolerance and hole/chip-forming configuration. The following numbers and suffixes identify the size, corner radius, geometry and manufacturer-specific chipbreaker. The four-letter family code alone is not enough to confirm cutter compatibility.
How to Read PDER and PEER in an APMT Designation
PDER and PEER are not chipbreaker names. They describe the wiper code, cutting-edge form and cutting direction. A chipbreaker code appears separately after the hyphen.
APMT1604PDER-M2PD is the wiper code, E is the cutting-edge form, R is the right-hand direction, and M2 is the finishing chipbreaker.
APMT1604PEERPE is the wiper code, followed by edge-form code E and right-hand code R. Because no chipbreaker suffix follows a hyphen, display the chipbreaker as /.
Complete APMT Insert Models and Specifications
All APMT1135 and APMT1604 models shown in the supplied carbide insert catalogue are listed below. Dimensions, chipbreakers and available grades are kept at full-designation level.
How to Use the Tables
Choose the insert platform from the cutter pocket first, then confirm the complete designation, chipbreaker, radius and available grade. A dot shown in the catalogue has been converted into a listed grade in the final column.

APMT1135 vs APMT1604
The correct platform is determined by the cutter pocket. Size selection is not interchangeable and should not be based only on the application name.
Smaller Insert Platform
- Used in smaller and medium compatible cutter bodies
- Confirmed cutter examples include TAP300R and BAP3
- Also used in selected RAP-75 and APE systems
- Lower cutter-body and machine-load direction
- Complete dimensions depend on geometry suffix
Larger Insert Platform
- Used in medium and larger compatible cutter bodies
- Confirmed cutter examples include TAP400R and BAP4
- Also used in TAP300R, RAP-75 and APE systems by model
- Longer and stronger cutting-edge direction
- Available with multiple catalogue corner radii
Compatible APMT Insert Cutters and Cutter Bodies
Search performance shows strong interest in APMT cutters and cutter bodies. The table below connects the insert platform to confirmed cutter systems from the supplied cutter catalogues.
Right-Angle Shoulder Cutters
General shoulder, side, pocket and related indexable milling applications.
Larger Shoulder Cutters
Larger cutting-edge platform for roughing and shoulder milling.
75° Face Milling Cutters
Face milling system with APMT platform selected by the complete cutter model.
Compact APMT Cutter System

APMT Chipbreaker Options
The chipbreaker is the suffix after the hyphen. PDER and PEER are part of the insert designation structure and must not be used as chipbreaker names.
No Chipbreaker Suffix
Use a slash when the complete designation ends with PDER or PEER and no separate suffix follows.
Черновая обработка
H2 is the roughing chipbreaker for stronger-edge and higher-load machining conditions.
Отделка
M2 is the finishing chipbreaker for lighter cutting and improved surface-finish direction.
Полуфабрикаты
ZL is the semi-finishing chipbreaker for balancing stock removal, cutting stability and surface quality.
APMT Inserts by Workpiece Material
Choose the complete size, geometry and grade combination. Not every grade is available in every APMT designation.
Сталь
Balance edge toughness, wear resistance and chip formation for shoulder, side and pocket milling.
Inserts for steelНержавеющая сталь
Use suitable PVD grades and lower-force geometry to reduce heat, work hardening and built-up edge.
Inserts for stainless steelЧугун

Inserts for cast ironАлюминий
Use only confirmed sharp, non-ferrous geometries and grades; standard coated APMT options are not automatically suitable.
Inserts for aluminumСложные материалы
Hardened and heat-resistant applications require application review, stable engagement and a verified grade combination.
Difficult-material insertsAPMT Milling Insert Applications
Actual capability depends on the cutter body. APMT is primarily associated with positive shoulder and general indexable milling systems.
Фрезерование плеча
Machining a horizontal floor and vertical wall with compatible right-angle cutters.
Фрезерование торцов
Selected RAP-75 and related cutter systems for flat-surface roughing and semi-finishing.
Боковое фрезерование
Peripheral cutting along walls, steps and external part features.
Карманное фрезерование
Roughing and profiling inside open pockets with a compatible cutter body.
Ramping
Angled entry where the individual cutter model supports a specified ramp angle.
Helical Interpolation
Circular entry or cavity opening where confirmed by cutter specifications.
Die-Sinking
Selected roughing and cavity work using positive indexable milling systems.
Selected Slot Milling
Only with cutter bodies designed and specified for slotting or full-width engagement.
APMT Corner Radius and Cutting Edges
The size code alone does not fully define corner radius. Use the complete designation and catalogue RE value.
Larger corner radii generally strengthen the edge and may support higher load, but they also increase cutting force and determine the minimum internal corner that can be produced.
How to Choose an APMT Insert
APMT vs APKT Inserts
APMT and APKT have a similar positive parallelogram form, but their tolerance class, dimensions, edge preparation and manufacturer-specific geometry may differ.
Do not assume interchangeability from appearance alone. Check the complete insert designation and cutter pocket.
Compatibility Identification
Mitsubishi, Widia, Walter and other brand names or product codes may be referenced on individual product pages for compatibility identification. Such references do not imply authorization, endorsement or original-equipment status. Compatibility must be confirmed from the full insert and cutter specifications.
Request APMT Insert Pricing
Send the full insert code, APMT1135 or APMT1604 size, chipbreaker, grade, corner radius, quantity and current cutter-body model. A photo of the cutter pocket or an existing insert can help confirm compatibility.
