◆Panoramica del prodotto
WNMU 040304, 060408 and 080608EN are carbide milling insert sizes offered for compatible 90° shoulder milling cutters. The series targets square-shoulder and side-milling operations where cutter rigidity, edge strength and chip evacuation matter. Choose the insert size and full suffix for the specified cutter pocket, then select the carbide grade and geometry for the workpiece and cutting load.
The supplied description presents a double-sided range for roughing. Actual usable-edge count, maximum axial depth of cut, coating and material range must be confirmed by complete item code and cutter-body drawing. A nominal 90° cutter designation alone does not guarantee a perfectly square wall or a flat pocket floor in every setup.
◆Key Configuration
Three WNMU Sizes
040304, 060408 and 080608EN identify separate size or geometry options. Match the exact designation to the manufacturer’s approved cutter pocket.
90° Shoulder Milling
Use a suitable square-shoulder cutter for wall and floor machining. Verify effective cutting diameter, maximum depth and corner geometry for the complete tool assembly.
Grade & Edges
Confirm carbide grade, coating, chipbreaker and usable edges by SKU. The original copy does not identify one verified PVD grade or common edge count for all three sizes.
◆Applications & Selection
The range may be considered for shoulder milling, side milling and roughing of carbon or alloy steel, stainless steel and cast iron when a suitable insert grade is available. Tool steel and heat-treated workpieces require grade-specific approval. Deep pocketing, slotting, ramping and heavy interrupted cuts depend on the cutter body’s stated limits and machine rigidity.

◆Specifications & Series
Three WNMU sizes are named in the supplied product description. No dimensioned drawing, complete grade codes or cutting data were provided for this exact HY series. The table distinguishes the listed models and the information needed to specify each one; do not treat the numeric code alone as a verified dimensional chart.
| Model Listed | Nominal Family | Confirm Before Ordering |
|---|---|---|
| WNMU 040304 | WNMU 04 | Full suffix, insert dimensions, corner geometry, grade and approved 04-size cutter pocket. |
| WNMU 060408 | WNMU 06 | Full suffix, insert dimensions, corner geometry, grade and approved 06-size cutter pocket. |
| WNMU 080608EN | WNMU 08, EN suffix | Complete geometry suffix, insert dimensions, grade and approved 08-size cutter pocket. |
◆Configuration to Confirm
| Selection Field | What to Confirm |
|---|---|
| Cutting system | Nominal 90° shoulder cutter; verify actual lead angle, tool overhang, seating and maximum axial depth with the cutter drawing. |
| Insert grade & coating | Carbide; verify substrate, PVD/CVD or other coating, chipbreaker and edge preparation by full SKU. |
| Workpiece group | Steel (ISO P), stainless steel (ISO M), cast iron (ISO K) or another material only with an approved grade and geometry. |
| Operation | Shoulder or side milling; check pocketing, slotting, ramping and entry limits against the complete cutter specification. |
| Wall & floor | Confirm corner geometry, tool deflection, step-down overlap and finish allowance for the required shoulder tolerance. |
◆How to Select the Insert
◆Starting Cutting Data
Select cutting speed (Vc), feed per tooth (fz), axial depth (ap) and radial engagement (ae) using the complete insert grade and shoulder-cutter recommendations. The original description provides no validated numerical range. A 90° shoulder cutter should not automatically use the chip-thinning feed multiplier of a low-entering-angle high-feed cutter.

◆Product FAQs
Are these 90° shoulder inserts also high-feed inserts?
This product title specifies 90° shoulder milling. Small-entering-angle high-feed milling relies on a different chip-thinning relationship and often uses shallower axial cuts. Choose speeds, feeds and depths from the exact WNMU insert and shoulder-cutter data rather than applying another high-feed system's settings.
Can WNMU 040304, 060408 and 080608EN fit the same cutter?
They are different size families. Verify the complete code against the cutter body's approved insert list and compare the pocket, seating surfaces, screw, corner form and specified tightening torque. A shared WNMU prefix does not establish interchangeability.
Does a 90° cutter guarantee an exact square shoulder?
The nominal entering angle describes the cutter geometry. Wall squareness and floor finish also depend on insert corner design, cutter runout, deflection, depth of cut and the machining setup. Use a finishing pass and measure the part when tolerances are tight.
How deep can these inserts cut?
Maximum axial depth varies by insert size, edge geometry and cutter body. The supplied description contains no verified ap limit for these three HY models. Request the matching cutter drawing and application data before programming a deep pass.
Which grade suits steel, stainless steel or cast iron?
Provide the exact workpiece grade and hardness, operation, coolant and cut stability. The carbide grade, coating and chipbreaker should be selected for ISO P, M or K as applicable; the WNMU size code alone does not identify material suitability.
How many usable edges does a WNMU insert have?
Some manufacturer's double-sided WNMU shoulder systems offer six usable edges, but confirm the actual indexing geometry and edge count for the complete insert and cutter being ordered. The supplied HY description does not document one edge count across all three sizes.
◆Ordering & OEM FAQs
What should I send for an insert replacement?
Send the current manufacturer's complete insert code and grade, box-label and both-face photos, cutter-body code, workpiece, cutting conditions, observed wear and required quantity. Validate pocket fit and cutting results with a sample.
Can I combine WNMU 04, 06 and 08 in one order?
Send a line-by-line list with the full code, grade and quantity for each model. Mixed-size availability, pack count, minimum quantity and dispatch date are confirmed for each item.
Can I request a different coating or edge geometry?
Provide the existing code or drawing, target material, operation, cutter body and expected volume. Available substrate, coating and edge options are confirmed through the approved specification and quotation.
