Insert Identification

What 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.

A standard APMT shoulder-milling geometry normally provides two usable cutting edges, but the complete insert and cutter design must still be checked.

Designation Structure

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.

APMTInsert FamilyShape, relief, tolerance and hole/chip-form configuration
16Size CodeCutting-edge-length code
04Thickness CodeNominal thickness code
PDWiper CodeP = 90° and D = 15° in the catalogue coding diagram
ECutting-Edge FormCatalogue edge-form code E
RCutting DirectionR = right-hand cutting direction
M2Chipbreaker CodeSuffix after the hyphen
APMT1604PDER-M2

PD is the wiper code, E is the cutting-edge form, R is the right-hand direction, and M2 is the finishing chipbreaker.

APMT1604PEER

PE 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 / and treat it as the semi-finishing version shown in the catalogue.

For the catalogue code shown in your attachment: PDER = PD wiper code + E cutting-edge form + R right-hand cutting direction. The chipbreaker is a separate suffix such as H2, ZL or M2. When no separate suffix is shown and the chipbreaker is written as /, treat that catalogue model as semi-finishing.
Dimensions & Specifications

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.

PDER and PEER are designation structures, not chipbreakers. H2 = roughing, ZL = semi-finishing, M2 = finishing, and “/” indicates the semi-finishing version without a separate chipbreaker suffix.

The PDER radius models provide RE values of 0.8, 1.2, 1.6, 2.0 and 3.0 mm. The complete designation must be used when ordering because the radius is part of the model code.
Size Comparison

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.

APMT1135

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
View all APMT1135 models
APMT1604

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

APMT1135 and APMT1604 are not interchangeable. Confirm insert size, thickness, mounting hole, corner radius, hand, suffix, screw and cutter-pocket geometry.
Chipbreaker Selection

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.

/

Semi-Finishing

Use a slash when the complete designation ends with PDER or PEER and no separate suffix follows. In this catalogue, those slash-designated models are used for semi-finishing.

H2

Roughing

H2 is the roughing chipbreaker for stronger-edge and higher-load machining conditions.

M2

Finishing

M2 is the finishing chipbreaker for lighter cutting and improved surface-finish direction.

ZL

Semi-Finishing

ZL is the semi-finishing chipbreaker for balancing stock removal, cutting stability and surface quality.

Code meanings: H2 = roughing, ZL = semi-finishing, M2 = finishing, and / = semi-finishing without a separate chipbreaker suffix.
Materials & Grades

APMT Inserts by Workpiece Material

Choose the complete size, geometry and grade combination. Not every grade is available in every APMT designation.

P

Steel

Balance edge toughness, wear resistance and chip formation for shoulder, side and pocket milling.

Inserts for steel
M

Stainless Steel

Use suitable PVD grades and lower-force geometry to reduce heat, work hardening and built-up edge.

Inserts for stainless steel
K

Cast Iron

Wear-resistant grades support stable cast-iron milling and selected dry conditions.

Inserts for cast iron
N

Aluminum

Use only confirmed sharp, non-ferrous geometries and grades; standard coated APMT options are not automatically suitable.

Inserts for aluminum
H/S

Difficult Materials

Hardened and heat-resistant applications require application review, stable engagement and a verified grade combination.

Difficult-material inserts
D530Steel and cast iron; toughness direction for interruption and less stable cutting.
D570Steel and stainless steel; general and more precise milling direction.
D580Steel and cast iron; stable and selected dry-milling conditions.
D7320General-purpose milling of steel, stainless steel and cast iron.
D8420AWear-resistant direction for stable cast-iron milling.
D9920SSelected hardened and difficult-to-machine material applications.
Grade availability must be checked against the complete size + chipbreaker + grade SKU. The grade overview is not an inventory promise for every APMT combination.
Milling Applications

APMT Milling Insert Applications

Actual capability depends on the cutter body. APMT is primarily associated with positive shoulder and general indexable milling systems.

01

Shoulder Milling

Machining a horizontal floor and vertical wall with compatible right-angle cutters.

02

Face Milling

Selected RAP-75 and related cutter systems for flat-surface roughing and semi-finishing.

03

Side Milling

Peripheral cutting along walls, steps and external part features.

04

Pocket Milling

Roughing and profiling inside open pockets with a compatible cutter body.

05

Ramping

Angled entry where the individual cutter model supports a specified ramp angle.

06

Helical Interpolation

Circular entry or cavity opening where confirmed by cutter specifications.

07

Die-Sinking

Selected roughing and cavity work using positive indexable milling systems.

08

Selected Slot Milling

Only with cutter bodies designed and specified for slotting or full-width engagement.

Corner Radius & Edges

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.

The supplied catalogue lists APMT1604 PDER options with RE values including 0.8, 1.2, 1.6, 2.0 and 3.0 mm.
Two Usable Cutting EdgesStandard positive APMT shoulder-insert geometry normally indexes between two cutting corners.
Small RadiusLower corner load and smaller part-corner capability, subject to the available SKU.
Large RadiusStronger edge direction with higher force and a larger remaining part radius.
Check Cutter ClearanceInsert radius, cutter geometry and pocket position jointly determine the generated shoulder corner.

Related Insert Family

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.
