    Grades

    WU25PD

    WU25PD

    Composition: With a multilayered PVD TiN-TiAlN coating and a high-quality, sub-micron, carbide substrate, this grade gives a high level of wear resistance at medium to high cutting speeds.
    Application: First choice for high reliability in all materials. This grade should be used at medium to high speeds and feeds. It is a general-purpose grade that performs very well for alloyed and high-alloy steel and cast iron, but can also be used with excellent performance in all other material groups.

    Features and benefits

    • Advanced-point geometry design offers the ultimate solution for multipurpose drilling operations. It offers dependable tool life in all materials due to less chipping on the cutting edge.• VariDrill core design offers free chip flow and chip evacuation.• Geometry design offers strength and versatility.• Delivers proper surface finish across multiple materials: steel, stainless steel, cast iron, aluminium, and high-temp alloys.• WIDIA WU25PD™ drilling grade: extremely high wear resistance and longer tool life.• Precision shank and marginless design for low runout.

    Create Solution to calculate Feeds and Speeds

    After creating a solution just choose the Feeds & Speeds icon and our system will provide recommendations. You can customize the information by adding your machine and specifications or make adjustments using the sliders.
