VNMG 1604 Series Overview
VNMG 1604 carbide turning inserts use a narrow 35° diamond geometry for external turning, facing, fine profiling and machining detailed component features. The pointed shape provides better access around shoulders, contours and restricted machining areas than wider insert geometries.
The series includes VNMG160404, VNMG160408 and VNMG160412, with grades and chipbreakers for steel and stainless steel. Customers building a broader CNC insert range can also view our carbide turning and milling inserts.
Models & Dimensions
Standard VNMG1604 dimensions are listed below. All dimensions are in millimeters.
| Model | Length L | I.C. | Thickness S | Hole Ød | Corner Radius r |

◆How to Select a VNMG 1604 Insert
For additional guidance, use the CNC Insert Selection Guide.
◆Starting Cutting Data
There is no single safe speed, feed or depth-of-cut range for every VNMG 1604 grade and chipbreaker. Obtain the cutting data for the complete insert code and exact workpiece grade. For turning, n = (1000 × Vc) / (π × D), where n is RPM, Vc is cutting speed in m/min and D is workpiece diameter at the cut in mm. Compare the proposed feed with the chipbreaker's operating window.
◆Related Series & Technical References
For a broader insert selection, see our carbide turning and milling insert range. Compare a DNMG 1504/1506 series when a 55° corner better fits the job.

◆Product FAQs
What is a VNMG 1604 insert used for?
Its 35° diamond point provides access for external turning, fine profiling and detailed contours with a compatible tool holder. Facing depends on the holder's approach angle and workpiece clearance. The narrow point is best selected for a suitable feed and depth of cut rather than assumed to suit heavy interrupted machining.
What changes between VNMG 160404, 160408 and 160412?
The supplied dimensions list the same VNMG 1604 body and nominal corner radii of 0.4, 0.8 and 1.2 mm. Smaller radii help access fine details and may reduce radial force. A larger radius supports the corner at suitable feed but needs more clearance and a rigid setup. Check the actual chipbreaker and finished-profile requirement.
Are the VNMG 1604 dimensions the same as cutting-edge length?
No. The supplied Overview labels 16.6 mm as Length L. Effective cutting-edge length may be defined differently in manufacturer catalogues and vary by corner radius or chipbreaker. Confirm the dimension definitions in the current drawing before comparing two brands.
Can the same VNMG insert machine both steel and stainless steel?
The page covers grades for both material groups, but a size code alone does not establish dual-material suitability. Specify the exact steel or stainless grade and hardness, then confirm the matching carbide grade, coating and chipbreaker for that workpiece and cut.
How do I choose between PMF, WM, SF, MF, FM and MM?
These are chipbreaker designations mentioned in the Overview, not universal geometry standards. Send your workpiece, holder, feed, depth of cut, coolant and chip-control problem. Confirm which suffix and grade combination is available for the selected corner radius and obtain its operating window.
How does VNMG differ from DNMG or WNMG?
VNMG has a 35° diamond corner suited to detailed profile access. DNMG uses a 55° diamond and WNMG an 80° trigon, which can provide more corner support where the part geometry allows. The actual holder, grade, chipbreaker and cutting conditions still govern selection.
◆Ordering & OEM FAQs
What should I send for a VNMG replacement request?
Provide the complete insert code, original manufacturer, grade and chipbreaker, box-label and insert photos, holder model, workpiece material, cutting parameters and required quantity. Check a proposed replacement for seat fit and machining performance before production use.
Are YC331, YP731 and YP753 direct equivalents to the reference grades?
No one-to-one equivalence is established by the Overview. Compare the supplier grade sheets, coating and application ranges, then conduct a controlled cut to assess chip control, tool wear, surface finish and cost per accepted part.
Can I combine different models and grades in one order?
The Overview offers mixed-model supply by confirmation. Send each full VNMG model, chipbreaker, grade and quantity as a separate line. Stock, minimum order quantity, packaging and delivery time are confirmed per item.
Can I request private-label packaging and product information?
The Overview lists neutral or branded boxes, customer SKU and barcode labels, plus product images and specifications for sales use. Send artwork, label details, item list and forecast quantity so the available options and lead time can be confirmed.
