Widia 3552619 Square End Mill 1/2 in 5 Flute Carbide

Product Description

The WIDIA 3552619 is a 5-flute solid carbide square end mill engineered for high-performance milling in demanding materials. It carries a 1/2 inch cutting diameter and a 1-1/4 inch length of cut, with a 3 inch overall length and a 38-degree helix angle. The WP15PE coating is designed to extend tool life and reduce heat buildup when cutting steel, stainless steel, superalloys, titanium, and hard materials. Right-hand cutting and right-hand flute geometry make this a standard orientation for conventional CNC milling setups. This tool is selected by machinists and tooling specialists working in production and job-shop environments.

The 3552619 belongs to WIDIA Series 5V0S and is suited for milling operations on steel, stainless steel, superalloys, titanium, and hard materials. The 5-flute configuration increases feed rates compared to 4-flute tooling while maintaining strong chip evacuation in medium-to-long cuts. The straight cylindrical shank at 1/2 inch diameter fits standard ER and side-lock toolholders. Center-cutting capability allows for direct plunge entry, adding versatility in slotting and pocket milling applications.

Key Features

• 5-flute solid carbide construction for rigidity and wear resistance in tough alloys
• WP15PE coating provides heat resistance and extended tool life on steel, stainless, superalloys, and hard materials
• 38-degree helix angle optimized for smooth cutting action and reduced vibration
• Center-cutting design allows direct plunge milling without a pre-drilled entry point
• Right-hand cut, right-hand flute orientation for standard CNC milling spindles
• Series 5V0S regular-length profile for consistent reach in standard milling fixtures

Compatibility

Designed for use on steel, stainless steel, superalloys, titanium, and hard materials as noted in WIDIA Series 5V0S tooling. The 1/2 inch straight cylindrical shank is compatible with standard ER collet chucks, Weldon side-lock holders, and hydraulic toolholders sized for 1/2 inch shank diameters.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the toolholder is clean and free of chips before loading the end mill. Confirm runout at the toolholder before cutting to avoid premature tool wear. Follow the machine tool manufacturer and toolholder manufacturer specifications for drawbar torque and clamping force.
