Iscar 3401315 Square End Mill 5/8 in 4 Flute Solid Carbide

Product Description

The ISCAR 3401315 is a single-end square end mill designed for milling operations in metal and alloy workpieces. Manufactured from submicron-grade solid carbide and coated with TiAlCN, it handles demanding cutting conditions where heat resistance and wear life are priorities. The 38-degree helix angle promotes efficient chip evacuation, and the variable index design reduces harmonic vibration during cut. At 5/8 inches in diameter with a 1-1/4 inch length of cut and 3-1/2 inch overall length, this tool is suited for slotting, profiling, and peripheral milling where a short-to-medium reach is appropriate. Machinists and tool-and-die professionals are the primary users.

This end mill is built for use in CNC machining centers and manual mills operating on ferrous and non-ferrous materials. The right-hand cutting and right-hand flute direction make it compatible with standard spindle rotation. The centercutting capability allows plunge entry without a pre-drilled hole, adding flexibility in 3D contouring and pocket milling applications. Four flutes provide a balance between chip clearance and surface finish, making it appropriate for both roughing passes at moderate depths and light finishing cuts.

Key Features

• Submicron-grade solid carbide construction for extended tool life in hard and abrasive materials
• TiAlCN coating provides heat and oxidation resistance at elevated cutting temperatures
• 38-degree helix angle promotes smooth chip flow and reduces cutting forces
• Variable index flute spacing dampens vibration and chatter during aggressive passes
• Centercutting design enables direct plunge entry without pilot drilling
• Right-hand cut and right-hand spiral for use with standard CNC and manual mill spindles

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual knee mills accepting a 5/8 inch straight shank end mill.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Use a calibrated torque wrench and appropriate collet or end mill holder rated for the 5/8 inch shank diameter. Verify runout with a dial indicator after seating to maintain dimensional accuracy and prevent premature tool wear.
