Grooving Inserts
Grooving Inserts for CNC Grooving, Parting and Slotting
Grooving Inserts are used in CNC turning operations to machine external grooves, internal grooves, parting cuts, slotting features, seal grooves and retaining ring grooves. A suitable grooving insert helps improve chip evacuation, reduce cutting vibration, maintain groove width accuracy and achieve stable metal cutting performance.
KEUE CNC focuses on carbide grooving inserts and related grooving tools for steel, stainless steel, alloy steel, cast iron, hardened steel and difficult-to-machine materials. As a grooving insert manufacturer, KEUE CNC provides different insert geometries, chipbreaker designs, coating options and tool structures for light, medium and heavy-duty grooving applications.
What Are Grooving Inserts?
Grooving inserts are replaceable cutting inserts mounted on grooving tool holders, parting tool holders or slotting cutter systems. They are designed with narrow cutting edges, rigid insert bodies and optimized chipbreakers to cut accurate grooves in limited machining spaces.
Compared with general turning inserts, grooving inserts focus more on chip control, groove width accuracy, cutting edge strength and workpiece surface protection. This makes them suitable for CNC lathes, turning centers and precision metal machining applications.
Grooving Insert Types Available
MGMN Grooving Inserts
MGMN grooving inserts are widely used for external grooving, parting-off and slotting. They are suitable for common groove widths such as MGMN200, MGMN250, MGMN300, MGMN400 and MGMN500. Different chipbreaker and coating options can be selected for steel, stainless steel and alloy steel machining.
MRMN Round Grooving Inserts
MRMN grooving inserts feature a round cutting edge for R-grooves, seal grooves and arc-profile groove machining. The round head design supports one-step forming, smooth groove surfaces and high contour accuracy.
7-Groove Blades
7-Groove Blades are designed for stepped shafts, short shafts and workpieces where fixture interference may occur. The special L-type structure helps reduce collision risk while improving cutting accessibility and rigidity.
Small-Hole Grooving Tools
Small-hole grooving tools are used for internal grooves and small bore machining. They are suitable for limited-space applications where tool rigidity, insert stability and accurate internal groove dimensions are important.
TKF Slotting Cutter Inserts
TKF slotting cutter inserts are suitable for CNC lathe slotting, grooving and parting applications. They are used when strong cutting performance and stable groove machining are required.
DGN and DGR Grooving Inserts
DGN and DGR grooving inserts are used for grooving and parting operations with different groove widths and cutting directions. They are suitable for CNC machining users who need stable cutting, accurate groove size and reliable insert performance.
PCD, Cermet and Special Grooving Inserts
For specific workpiece materials or machining requirements, PCD, cermet and coated grooving inserts can be selected. These options are suitable for cast iron, non-ferrous materials, hardened parts, stainless steel, titanium alloy and other difficult-to-machine materials.
Key Features of KEUE Grooving Inserts
Stable Chip Control
Optimized chipbreakers help guide chips away from the cutting zone, reducing chip jamming, workpiece scratching and unstable cutting. This is especially important in grooving and parting operations where chip evacuation space is limited.
Accurate Groove Width
Grooving inserts are designed to maintain consistent groove width during CNC machining. A stable cutting edge helps improve repeatability in batch production and reduces dimensional variation between parts.
Strong Cutting Edge Design
The insert structure is designed for reliable performance during grooving, parting and slotting. Strong cutting edges help reduce insert breakage, especially in interrupted cutting or medium-duty machining conditions.
Coating Options for Different Materials
PVD, CVD, TiAlN and other coating options can be selected according to workpiece material and cutting conditions. Wear-resistant coatings are suitable for steel and alloy steel, while low-friction coatings help reduce built-up edge in stainless steel and difficult materials.
Cost-Effective Insert Use
Many grooving inserts use double-ended or multi-edge designs. After one cutting edge wears out, the insert can be rotated or indexed, helping reduce tooling cost per part and improve insert utilization.

How to Choose the Right Grooving Insert
When selecting a grooving insert, buyers should consider groove width, groove depth, workpiece material, cutting speed, feed rate, tool holder compatibility and machining stability.
For general grooving and parting, MGMN inserts are commonly selected. For R-grooves and seal grooves, MRMN round inserts are more suitable. For internal grooves or small bore applications, small-hole grooving tools should be considered. For hard materials, stainless steel or titanium alloy, coating and carbide grade selection become more important.

FAQ
Q1: What are Grooving Inserts used for?
A1: Grooving Inserts are used for CNC grooving, parting-off, slotting, seal grooves, retaining ring grooves, R-grooves and shaft groove machining.
Q2: What is the difference between MGMN and MRMN grooving inserts?
A2: MGMN inserts are commonly used for straight grooving, parting and slotting, while MRMN inserts have a round cutting edge for R-grooves, seal grooves and arc-profile machining.
Q3: Can Grooving Inserts be used for stainless steel?
A3: Yes. For stainless steel machining, suitable carbide grades and low-friction coating options help reduce built-up edge, improve chip evacuation and extend tool life.
Q4: How do I choose the correct grooving insert?
A4: Choose according to groove width, groove depth, cutting direction, workpiece material, tool holder type, cutting condition and required groove accuracy.
Q5: Why is chip control important in grooving?
