DCGT070201-FN2 WNN10 turning indexable insert by Walter Tools — coated cemented carbide, FN2 chipbreaker

The DCGT070201-FN2 WNN10 is a compact turning insert designed for productive external turning and fine finishing tasks in general workshop and industrial turning operations

• Coated carbide grade WNN10 for versatility
• Rhombus 55° geometry for secure seating
• 0.1 mm corner radius for precise contouring
• FN2 chipbreaker tuned for stable chip control

Greater process reliability from a coated carbide grade

The WNN10 grade is a coated cemented carbide designed to deliver balanced performance across a broad range of turning tasks. As a result, the insert offers improved wear resistance compared with uncoated grades while maintaining cutting-edge stability. The coating reduces flank adhesion and heat-related wear, which translates into longer effective tool life and fewer index changes in batch production. In practical terms, this means fewer interruptions on the shop floor and a more predictable production rhythm — an economic advantage when consistent component quality is required.

Geometry and chip control that support precision work

The Rhombus 55° form combined with a 0.1 mm corner radius provides a fine compromise between edge strength and finishing capability. This geometry supports narrow clearance between insert and component, enabling precise contour definition and good surface finish without sacrificing edge security. The 7° relief angle reduces rubbing at the flank and helps maintain a stable cutting edge under moderate feeds. Together with the FN2 chipbreaker, the insert promotes short, controllable chips and reduces the risk of chip entanglement — a key benefit for turning centres and lathes where machine uptime and operator safety are priorities.

Integration, specification and selection guidance

Marked as DCGT070201-FN2 in the Walter range and designated DCGT070201-FN2 WNN10, the insert follows established format conventions (size 07, thickness 02) and is manufactured to tolerance class G. It is intended for use in toolholders that accept the DCGT geometry; matching the insert to the correct holder and cutting parameters ensures optimal performance. Note that the series is Walter Schneidstoffsorte - Serie offen and that material suitability should be verified using the manufacturer’s product matrix — this step is recommended to confirm the best feed and speed window for a given workpiece material. Correct selection reduces rework and improves the cost-efficiency of machining cycles.

FAQ

What materials is this insert suited for?
The DCGT070201-FN2 WNN10 insert is a coated cemented carbide grade intended for a broad material spectrum; verify specific workpiece suitability using the Walter product matrix for the WNN10 grade.

How does the FN2 chipbreaker affect machining?
The FN2 chipbreaker promotes controlled, short chips and reduces chip stringing; this supports stable cutting and easier post-process handling when using the DCGT070201-FN2 insert.

Is the insert compatible with standard DCGT toolholders?
The insert follows the DCGT geometry (size 07, thickness 02) and is designed for holders that accept DCGT-style turning inserts; confirm holder compatibility before assembly.

What advantage does the 0.1 mm corner radius provide?
A 0.1 mm corner radius balances edge strength with the ability to produce fine surface finishes and precise contours, making it suitable for finishing passes and detailed profiles.

Are there any special recommendations before use?
Consult the Walter Tools product matrix for WNN10 to determine optimal feeds and speeds for the intended workpiece material; this ensures the best combination of tool life and surface quality.
