WCMT 03/04/05/06/08-PG | Universal U-Drill Insert

ZANHO WCMT-PG series is a high-performance indexable drill insert designed for universal drilling in carbon steel and alloy steel. Featuring a unique array of spherical chipbreaker dots on the rake face, it significantly expands the chip-breaking window and improves evacuation of wide chips. With its reinforced negative land edges and 2-edge trigon geometry, it provides excellent reliability when drilling through rough forging surfaces and oxide scales.

Key Performance & Features

Universal Drilling Specialist: Specifically optimized for high-volume production in Carbon Steel, Alloy Steel, and Cast Iron materials.
Spherical Dot Array Technology: The rake face is covered with a dense array of spherical chipbreaking dots that force wide drilling chips to curl and fracture, preventing flute clogging.
Reinforced Impact Resistance: Controlled negative land on the cutting edge enhances toughness, allowing the insert to handle the initial shock of drilling into forging crusts or materials with light oxide scales.
Stable Chip Evacuation: Engineered to provide consistent performance even in deep-hole drilling where chip curling and smooth flow are critical for surface finish and hole accuracy.
Economic 2-Corner Logic: The trigon geometry provides two sharp and robust cutting corners, maximizing tool life and reducing the tool cost-per-hole.
