P4460-2R08-G88 WNN15 – Drill / reaming indexable insert by Walter Tools, coated carbide with 2R08-G88 chipbreaker

The P4460-2R08-G88 WNN15 is a coated carbide indexable insert designed for drilling and bore-enlarging tasks where reliable chip control and repeatable tool life are required; suitability for specific workpiece materials must be confirmed with the product matrix

• Coated carbide grade WNN15
• Optimised 2R08-G88 chipbreaker
• For drilling and bore enlargement
• Walter open-series cutting grade

Consistent holemaking through a robust cutting grade

The core advantage of this insert is its WNN15 cutting grade, a coated carbide class engineered for general-purpose performance within Walter's open series. The coating and substrate combination prioritises wear resistance and stable edge geometry, which together reduce the frequency of index changes and support predictable tool life. As a result, machining cycles benefit from fewer interruptions and improved process repeatability. For integrators and production engineers this means a more reliable cutting tool package that fits into established drilling and reaming toolholders.

Precise chip control and reduced rework

The 2R08-G88 chipbreaker is specifically shaped to control swarf formation during drilling and bore enlargement, improving evacuation from the cutting zone and lowering the risk of built-up edge. Effective chip control helps maintain hole quality and surface finish while reducing the likelihood of tool-induced damage to the workpiece. In practical terms, this leads to fewer secondary operations and higher first-pass yields, supporting a more economical manufacturing flow without sacrificing component tolerances.

Practical selection and application guidance

Selection must be guided by the product matrix: the WNN15 grade is a coated carbide class intended for a variety of applications, but exact material suitability depends on the specific workpiece and cutting parameters. The insert is supplied under Walter’s open series philosophy, enabling flexible application across different tool systems. When assessing the insert for a job, note the chipbreaker geometry and intended cutting data; these determine achievable feeds and speeds as well as the optimal coolant strategy. For questions about compatibility with a particular toolholder or workpiece material, consult the technical documentation or the product matrix.
