SANDVIK COROMANT

Sandvik Coromant is a brand within Sandvik Machining Solutions, a division of the Swedish engineering group Sandvik AB. The brand's history in metal cutting extends back to the mid-20th century, when Sandvik developed cemented-carbide tooling for industrial machining. Today, Sandvik Coromant supplies indexable inserts, tool holders, and modular tooling systems used in turning, milling, drilling, and threading operations. The product range covers common ISO insert geometries and grades designed for specific workpiece materials and machining conditions. Grades such as 1025, 1125, 1145, and 4325 appear across the line, each formulated for a balance of wear resistance and toughness in steel, stainless steel, and cast iron. Coatings are applied to extend tool life in continuous and interrupted cuts. Insert geometries include -GM for medium machining and specialized forms for parting, grooving, and threading. The catalog includes external and internal grooving inserts, face grooving tools, cut-off inserts, and threading inserts for CNC lathes, turning centers, and automatic screw machines. Many inserts are indexable, allowing multiple cutting edges per insert before replacement. Tool holders and clamping systems are designed to match insert geometries and machine interfaces. 3G Electric supplies Sandvik Coromant tooling as part of its industrial equipment distribution. The current catalog includes 568 SKUs spanning turning, milling, threading, and grooving applications. Products are available for global shipment. Technical buyers can reference manufacturer part numbers such as 328R13-400 VM-TH 1025, N151.2-250-5E 1125, and N123K2-0635-0003-GM 4325 when specifying replacements or new tooling. 3G Electric provides access to these items without regional restrictions, supporting maintenance, procurement, and production teams that require specific insert grades and geometries. The line is relevant to industries including general machining, automotive component production, aerospace part manufacturing, and energy equipment fabrication, where consistent chip control and dimensional repeatability are required. For engineers selecting tooling, the key variables are workpiece material, operation type (turning, grooving, threading, parting), machine interface, and desired balance of productivity and tool life. Sandvik Coromant organizes its inserts around these variables, and 3G Electric maintains inventory across the common grades and geometries. This allows buyers to source items such as N151.2-300-5E 1125 for parting and grooving, or TLG-2047R 1125 for external and internal grooving, alongside threading inserts like 328R13-400 VM-TH 1025. The catalog also includes right-hand and neutral designs, and inserts for automatic screw machines where small-part machining demands precise groove dimensions and clean part separation. 3G Electric's role is to make these items available to industrial buyers worldwide, with part-number-level identification and specification data to support procurement decisions.

Frequently asked questions

Common questions about SANDVIK COROMANT from 3G Electric.

What Sandvik Coromant insert grades are available through 3G Electric?

The catalog includes grades such as 1025, 1125, 1145, and 4325. Grade 1025 is used in threading and grooving inserts for medium-duty steel machining. Grade 1125 appears in parting and grooving inserts for steel, stainless steel, and cast iron. Grade 1145 is used in cut-off and grooving inserts. Grade 4325 is a carbide grade with GM geometry for medium machining, offering a balance of wear resistance and toughness. Availability depends on the specific part number and insert geometry.

What is the difference between Sandvik Coromant N151.2 and N123K2 inserts?

N151.2 inserts are parting and grooving inserts used in CNC lathes and automatic screw machines. Examples include N151.2-250-5E 1125 and N151.2-300-5E 1125, both in grade 1125 for steel, stainless steel, and cast iron. N123K2 inserts, such as N123K2-0635-0003-GM 4325, are carbide inserts with GM geometry for medium machining in grooving, parting, and turning. The N123K2 uses grade 4325, which provides a different balance of wear resistance and toughness compared to grade 1125.

Can Sandvik Coromant threading inserts be used on CNC lathes?

Yes. Sandvik Coromant threading inserts such as 328R13-400 VM-TH 1025 are designed for precision thread cutting on CNC lathes and turning centers. They create internal or external threads in metal workpieces. The insert is intended for medium-duty steel machining. When selecting a threading insert, confirm the thread pitch, insert size, and holder compatibility for your machine. The 328R13-400 VM-TH 1025 is one example in the catalog; other threading geometries may be available depending on the application.

What Sandvik Coromant inserts are used for cut-off operations?

Cut-off operations use parting and grooving inserts such as N151.2-250-5E 1125, N151.2-300-5E 1125, and QD-NF-0250-0001-CO 1145. These inserts are used in CNC lathes and turning centers for clean part separation and consistent groove dimensions. The N151.2 series is suited to steel, stainless steel, and cast iron. The QD-NF-0250-0001-CO 1145 is another option for cut-off and grooving. Selection depends on workpiece material, machine type, and the required groove width and depth.

Are Sandvik Coromant grooving inserts available for external and internal grooving?

Yes. The catalog includes inserts for external and internal grooving, face grooving, and parting-off. One example is TLG-2047R 1125, an indexable grooving insert used in turning centers and lathes for producing grooves in metal components. Another is MB-09FB150-02-14R 1025, a right-hand parting and grooving insert with grade 1025 coating for wear resistance. These inserts are used in precision grooving and parting-off applications. Confirm the insert width, depth capacity, and holder interface for your specific operation.

How do I identify the correct Sandvik Coromant insert for my machining operation?

Start with the operation type: turning, milling, threading, parting, or grooving. Then match the workpiece material to the insert grade. For steel, stainless steel, and cast iron, grades 1125 and 1145 are common in parting and grooving. For medium machining with a balance of wear resistance and toughness, grade 4325 with GM geometry is used. Next, confirm the insert geometry and size against your tool holder. Manufacturer part numbers such as N151.2-250-5E 1125 or 328R13-400 VM-TH 1025 provide the specific grade, geometry, and size. 3G Electric lists these part numbers to support accurate ordering.
