LNHU130625R-L55T WSP45G milling insert by Walter Tools — Tiger·tec Gold, negative 0° free angle

LNHU130625R-L55T WSP45G is a rectangular indexable milling insert designed for heavy-duty and versatile milling applications in steels, stainless steels and heat-resistant alloys

• Tiger·tec Gold PVD coating
• WSP45G: versatile P/M/S grade
• Rectangular shape, 2.5 mm corner radius
• Negative 0° free angle for heavy cuts

Faster cycle times through robust coating and grade

The combination of the Tiger·tec Gold coating and the WSP45G grade provides a measurable advantage in productivity: the PVD-coated, wear-resistant cutting surface reduces flank wear and extends edge life, allowing for longer uninterrupted runs. The chemistry and layer design of the coating improve heat resistance and adhesion, which is particularly beneficial when machining steel and stainless steel where temperatures rise quickly. As a result, milling operations can run more consistently, with fewer insert changes and less unplanned downtime, supporting a more economical production flow.

Consistent chip control and stable cutting performance

Built with a dedicated chipbreaker L55T and a rectangular geometry, this insert promotes reliable chip formation across a range of cutting conditions. The 2.5 mm corner radius increases edge strength for interrupted cuts and roughing passes, while the negative 0° free angle gives a robust cutting edge suitable for higher engagement and material removal. Together, these features reduce the risk of built-up edge and brittle chipping, delivering improved surface quality and repeatable component tolerances—advantages that matter for batch production and tight machining windows.

Precision fit and straightforward integration into existing toolholders

Manufactured to tolerance class H, the insert meets high positional and dimensional standards, ensuring predictable seating and repeatable results in standard rectangular cutters. The designation and dimensions align with common ISO-compatible holders, simplifying tool management and inventory. Given the insert’s suitability for the ISO material groups P, M and S, it is a practical choice for shops handling mixed production—ranging from general structural steel components to corrosion-resistant and high-temperature alloy parts.

Application guidance and selection advice for reliable results

For roughing and semi-finishing on unalloyed or alloyed steel and stainless steel, the combination of WSP45G and Tiger·tec Gold delivers a balance of toughness and wear resistance. When machining titanium or nickel-based superalloys, moderate cutting parameters with active coolant and conservative feed per tooth help to maintain edge life and thermal stability. The insert’s chip control geometry supports a wider range of cutting depths; however, for critical component tolerances or unfamiliar alloys, a short trial under representative conditions is recommended to fine-tune spindle speed and feeds.

If further specification data or cutting-parameter recommendations are required, our technical team can provide tailored guidance based on the specific machine, holder and workpiece material. Contact details and assistance are available to ensure the insert integrates smoothly into existing processes.

FAQ

What materials is this insert suitable for?
The insert is formulated in the WSP45G grade and the Tiger·tec Gold coating, making it suitable for steel, stainless steel and heat-resistant superalloys/titanium in accordance with ISO 513 group assignments.

How does the negative 0° free angle affect machining?
A negative 0° free angle produces a stronger cutting edge and higher radial stability, which is advantageous for heavy cuts and interrupted milling where edge robustness is required.

Which chipbreaker should be used for general roughing?
The integrated chipbreaker L55T is optimised for consistent chip formation during roughing and semi-finishing, helping to avoid long stringy chips and improving evacuation in typical milling operations.

Is the insert compatible with standard toolholders?
Yes, the dimensions and tolerance class H ensure compatibility with ISO-standard rectangular milling holders that accept the stated insert size and thickness.

Can this insert be used for finishing operations?
While primarily designed for robustness and productivity, the insert can perform light finishing when combined with conservative feeds and fine depth of cut; for high-precision finishes, a dedicated finishing grade may be preferable.
