Product Drawings & Model Reference
Grade & Application Confirmation
The product title specifies cermet inserts for steel finishing. Neither supplied image identifies the cermet substrate grade, coating, edge preparation or recommended steel hardness range for these two FG codes. Confirm the material and grade on the supplier's box label or approved specification before publishing a grade-specific claim.
The broad workpiece list in the model-breakdown image does not verify suitability for stainless steel, hardened steel, cast iron or aluminum with these FG variants. Evaluate each material and cutting condition separately.
How to Select the FG Insert
Holder fit: Match the 09T3 CCMT size, seat, fixing hole, clamp and tool orientation to the holder or boring bar.
Corner radius: Choose 0.4 or 0.8 mm according to finish, feed, profile clearance and setup rigidity. A larger radius can raise radial force and vibration risk in slender or boring setups.
Grade: Confirm the exact cermet grade and FG geometry for the steel grade, stock allowance, cut continuity and coolant before machining.
Starting Cutting Data
The supplied images do not give cutting speed, feed or depth-of-cut values for FG cermet. Obtain the selected grade's recommended range, then adjust for steel grade, hardness, finish allowance, bar overhang and coolant. Validate chip control, surface finish and edge wear in a trial cut.
For more on insert shape, nose radius, chipbreaker and grade selection, see our CNC Insert Selection Guide.
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.

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. |
Order & Delivery

Product FAQs
What is the difference between CCMT09T304-FG and CCMT09T308-FG?
The supplied FG table gives both inserts the same L 9.7 mm, IC 9.525 mm, thickness 3.97 mm and fixing-hole diameter 4.4 mm. CCMT09T304-FG has a 0.4 mm corner radius; CCMT09T308-FG has a 0.8 mm radius.
Which radius should I choose for steel finishing?
Select the radius in relation to the required surface finish, feed, stock allowance and rigidity. A 0.4 mm radius can help with finer features and lower cutting force; a 0.8 mm radius may provide more corner support in a stable setup. Check the FG chipbreaker's recommended operating range for the exact cermet grade.
Are the FG inserts suitable for internal boring?
They may be considered with a compatible CCMT 09-size boring bar. Confirm insert seat, clamp, tool orientation, minimum bore, clearance and bar overhang. The insert chart alone does not establish a minimum bore size or maximum overhang.
Which cermet grade and coating do these FG inserts use?
The supplied images do not name a substrate grade or coating for the FG rows. Confirm the grade designation, coating and edge preparation from the product label or supplier specification before selecting cutting data.
Can I use these inserts for stainless steel, hardened steel, cast iron or aluminum?
The general product-information image lists several workpiece materials, but it does not establish an FG grade or application range for each material. This page is positioned for steel finishing; confirm any other workpiece against the exact grade's application data and a machining trial.
Does the “diamond insert” description mean PCD?
No. In the supplied model image, “diamond” describes the 80° rhombic insert shape. It does not identify a polycrystalline diamond cutting material. Confirm that the supplied FG variant is cermet through its grade specification.
Ordering & OEM FAQs
What should I include in an inquiry?
Send CCMT09T304-FG or CCMT09T308-FG, quantity, holder or boring-bar model, steel grade and hardness, operation, finishing allowance, current cutting conditions and required surface finish. Include the grade code or box-label photo when replacing an existing insert.
Can I request a specific grade or custom packaging?
Provide the requested grade, coating or performance target and the packaging or branding requirements. Material, availability, MOQ and lead time must be confirmed for the selected full ordering code.
Are CCMT09T304-HQ, -MT or -TC equivalent to -FG?
Not automatically. The supplied images show HQ in an illustrative model breakdown and MT/TC as separate table rows. Suffixes can identify different chipbreaker designs; compare the complete code, grade, application range and holder fit before treating another suffix as a replacement.
