◆How to Select a Compatible DNMG Insert
For a broader selection process, see the CNC Insert Selection Guide.
◆Starting Cutting Data
The supplied dimension chart does not give cutting speed, feed or depth-of-cut ranges. Select starting values only after confirming the exact carbide grade, coating, chipbreaker, steel or stainless-steel grade, holder overhang and coolant. Record the full setup before changing parameters.
◆Related Series & Technical References
Compare other turning-insert shapes in the carbide turning and milling insert range. For the complete DNMG code, compatible holder, grade-specific cutting data or a quotation, send your workpiece and insert requirements.
◆Carbide Insert Customization & OEM
Specify the insert around the machining operation, workpiece and holder. We can review standard replacements, application-specific geometry and private-label requirements using your insert designation, drawing or sample. Available grades, coatings, dimensions and order quantities are confirmed for each requested series.
Geometry & Chip Control
Review chipbreaker, rake, cutting-edge preparation, nose radius and corner design for the operation and workpiece. Confirm holder compatibility before approving a modified geometry.
Substrate & Coating
Select an available carbide grade and coating for the workpiece material, cutting conditions and desired balance of wear resistance and edge toughness.
Dimensions & OEM
Review insert size, thickness, locating and clamping features, tolerances, laser marking and private-label packaging against the approved specification.
◆Customization Options
Use the fields below when sending an inquiry. The exact options depend on the insert family and are confirmed in the quotation or approved drawing.
| Specification | Details to Confirm |
|---|---|
| Insert Type | Turning, milling, threading, grooving or drilling insert; send the designation or drawing. |
| Size & Fit | Shape, size, thickness, inscribed circle or edge length, hole or clamping form, and holder model. |

◆How to Request a Custom Insert
Send your insert requirements through our contact form or review our OEM and private-label service.
◆Carbide Insert Quality Control
Insert quality depends on the approved grade, geometry, coating and dimensional specification. We review the requirements at order confirmation and align the inspection scope with the insert series and any customer drawing. Share critical dimensions or documentation needs before production so they can be included in the agreed inspection plan.
01 · Incoming Material
Confirm the specified carbide grade or material documentation against the order requirements.
02 · In-Process Checks
Review dimensions and cutting-edge features during production against the approved specification.
03 · Final Inspection
Check the agreed dimensions, appearance, edge condition, coating identification and marking as applicable.
04 · Packing Review
Verify the item code, quantity, labels and protective packing against the approved order.
◆Inspection & Documentation
Inspection points and acceptance criteria should be agreed for the ordered series. For custom inserts, the approved drawing takes priority over a generic catalogue description.
| Check Area | What to Confirm |
|---|---|
| Dimensions & Fit | Insert size, thickness, corner radius, clamping features and any drawing tolerances. |
| Cutting Geometry | Chipbreaker, edge preparation, usable corners and profile where applicable. |
| Grade & Coating | Approved grade and coating designation; any requested verification method. |
| Appearance & Packing | Visible edge damage, marking, item code, count and packing format. |
| Requested Records | Inspection report, material or coating documentation, sample approval or batch identification when agreed. |

◆Product FAQs
What is the difference between DNMG1504 and DNMG1506?
The supplied chart lists the same 12.7 mm inscribed circle and 5.16 mm fixing-hole diameter for both groups. DNMG1504 is 4.76 mm thick; DNMG1506 is 6.35 mm thick. Check the holder seat and clamp before changing thickness, even when the insert shape and nose radius match.
Which corner radii are listed for this DNMG series?
The listed 04, 08 and 12 endings correspond to 0.4, 0.8 and 1.2 mm corner radii. Each radius appears in both thickness groups in the supplied chart. Choose the radius with the required profile, feed, finish and machine rigidity in mind; also verify the complete suffix and grade.
Are these DNMG inserts suitable for both steel and stainless steel?
The DNMG shape alone does not determine material suitability. Provide the workpiece grade and hardness, operation, continuous or interrupted cut, coolant and required finish. Confirm a carbide grade, coating and chipbreaker approved for the specific steel or stainless-steel application.
What do the HQ and CQ suffixes mean?
HQ and CQ identify supplier-specific cutting geometries in the supplied dimension chart. Five listed 1504/1506 models have HQ; DNMG150612 has CQ. The chart does not define their feed and depth-of-cut ranges, so confirm the chipbreaker application and availability for the complete ordering code.
Is DNMG150608-MA available in this series?
The illustration uses DNMG150608-MA to explain the designation, but the dimensional rows list DNMG150608-HQ instead. The example does not establish MA availability, grade or cutting data. Request confirmation if MA is the geometry you need.
Can a matching DNMG size code replace another manufacturer's insert?
Compare the full code, thickness, hole and seat dimensions, chipbreaker, edge preparation, grade and coating. Verify the holder fit and test the proposed replacement on the actual workpiece. A matching nominal size does not guarantee the same chip control or tool life.
◆Ordering & OEM FAQs
Can I combine DNMG1504 and DNMG1506 models in one order?
Send a line-by-line list with each complete model, geometry suffix, carbide grade and quantity. Mixed-model supply, minimum quantity, stock status and lead time are confirmed for the selected combinations.
How many inserts are packed per box?
The supplied Overview lists 10 pieces per box as a reference. Confirm the pack quantity and box-label details for the exact model and grade in the quotation, especially for mixed-model orders.
Are neutral or private-label boxes available?
The Overview offers neutral and private-label packaging by confirmation. Provide your artwork, barcode or customer SKU, required label information, model mix and quantity so the packaging specification and lead time can be reviewed.
What should I send for a sample or quotation?
Provide the complete DNMG code and grade, holder model, steel or stainless-steel grade, operation, current cutting conditions, quantity and packaging needs. For replacement matching, include photos of the original insert and box label, then compare sample wear, finish and chip control under recorded conditions.
◆Guides & Technical References
Use the CNC Insert Selection Guide for shape, nose-radius, grade and chipbreaker selection. The Carbide Insert Types Guide explains other turning-insert families.
For a model-specific drawing, grade-specific cutting data or quotation, send the complete DNMG and holder codes with your workpiece, application and quantity.
