Assorted carbide turning inserts

Carbide Inserts

Find carbide inserts for turning, small parts machining, grooving and parting, threading, milling and shallow-hole drilling. Choose by the feature you need to cut and the tooling already on your machine.

For a replacement, start with the full insert and tool-body references. For a new job, start with the part drawing, material and operation, then select the geometry and grade.

Send your existing insert reference or email a part drawing to discuss the job.

Find an Insert for Your Machining Task

A turning profile, a narrow groove and a drilled hole need different cutting edges and tool connections. Choose the operation below to compare the relevant shapes and sizes.

These inserts use cemented carbide. If your process calls for a different cutting material, compare Cermet, Ceramic, PCD or CBN or PCBN tools. See Cutting Tool Products for other machining tools.

Cutting tools arranged in a storage rack

Turning Inserts

For roughing, finishing, facing and profiling. Compare positive and negative styles around cut depth, access and the existing holder.

Small Parts Machining Inserts

CCGT, DCGT and TCGT for small-parts turning requirements. Compare nose shape, radius and tool clearance around the component.

Grooving and Parting Inserts

MGMN inserts for grooves and cut-off operations. Match cutting width and corner radius, then check reach with the holder or blade.

Threading Inserts

For thread turning, whirling and insert-based thread milling. Match the thread standard, pitch and profile to the tooling system.

End mills arranged by size

Milling Inserts

Replace inserts in an existing milling cutter. Match the complete insert designation and seating dimensions to the cutter pocket.

Drills arranged in a storage rack

Shallow Hole Drilling Inserts

SPMG and WCMX replacements for a specified drill body. Identify the pocket position before choosing geometry and grade.

Compare what each operation needs from the cutting edge and tool connection.

Match the Cutting Edge to the Feature

Use the feature and the existing tool system to narrow the choice. A familiar insert shape is only part of the match.

Keep the geometry suffix and grade with the size code. Two inserts can fit the same pocket yet cut differently because their edges and grades differ.

End mills in a tool rack
Insert type Machining task First selection decision
Turning Inserts Roughing, finishing or profiling Shape and clearance for access; edge geometry for the cut
Small Parts Machining Inserts Turning small diameters and close features Nose shape and radius with tool-block clearance
Grooving and Parting Inserts Cutting a groove or separating a part Cutting width and corner radius with usable reach
Threading Inserts Producing a specified thread Standard, pitch, profile and machining method
Milling Inserts Replacing a cutter’s cutting edges Full insert reference and cutter-pocket fit
Shallow Hole Drilling Inserts Replacing inserts in a drill body Body reference and designated insert position

After choosing the operation, check how the insert fits and how it will cut.

Check Insert Selection Factors

Balance Fit, Geometry and Grade

The insert must fit the tool, reach the feature and suit the cutting conditions. Work through those decisions before choosing a grade from the material name alone.

  • Tool fit: match the insert shape, dimensions, seating surface and clamping arrangement.
  • Feature access: check the cutting edge and holder against shoulders, groove walls or the hole opening.
  • Geometry: choose the edge and chipbreaker around the cut depth, feed and chip-clearance conditions.
  • Grade: use the workpiece grade, hardness and continuous or interrupted cut to narrow the choice.
  • Acceptance: define the finished dimensions and surface requirement so a trial can be measured.
  • Replacement: keep the full reference and current cutting conditions with any wear or breakage photos.
Tool production machinery

For an existing setup, identify what needs to improve: chip control, edge life, finish or dimensional consistency. That makes it easier to assess a geometry or grade change.

Use the Carbide Insert Identification Guide to decode an unfamiliar label. For a special profile, email the drawing to discuss Custom Cutting Tools.

Tell us which feature or machining result needs attention, together with the current insert reference.

Discuss an Insert Application

Identify the Size and Ordering Details

Use the insert drawing to compare dimensions. Symbols differ by insert type: a groove width, turning nose radius and thread pitch describe different parts of the cutting edge.

  • Read the complete label, including geometry suffix and grade.
  • Match the size and mounting dimensions to the existing tool.
  • Check the cutting feature: nose radius, groove width, thread profile or drilling geometry.
  • Keep the holder, cutter-body or drill-body reference with the insert designation.
  • State the required quantity and whether the request is a repeat order or a change to the process.

Define the Insert and Part Inspection

Specify the insert dimensions or records needed with the order. For a cutting trial, define the finished-part limits and how they will be measured.

See MSU Factory and Quality Control for equipment and tool-measurement information.

Keep the full insert reference and process conditions with trial measurements. This makes a later replacement or grade change easier to compare.

State any insert measurements and inspection records required before ordering.

Carbide Inserts Questions

What should I send for an exact replacement?

Send the complete insert designation, geometry suffix, grade and quantity, or the previous order number. Include the holder or tool-body reference when changing brands or when the fit is uncertain.

Can you help if the insert code is worn off?

Email clear photos of both faces, the side and the seat, plus the package label if available. Include the tool-body code and measured dimensions so the replacement can be identified.

Why can two inserts with the same size cut differently?

The edge preparation, chipbreaker and grade can differ even when the mounting dimensions match. Keep those details when comparing chip control, finish or edge life.

Can I use one grade for every material?

Choose the grade for the actual material and cutting conditions. Hardness, interruptions and the type of operation affect the selection; a material group alone is not a complete recommendation.

How should I describe a machining problem?

Identify the affected feature and the result you want to improve. Include the insert reference, material, cutting conditions and photos or measurements of the problem.

How are availability and delivery confirmed?

The quotation confirms the selected insert, quantity, availability and delivery timing. Include the destination and required date with the inquiry.
