Iscar 3401282 Square End Mill 7/16 in 4 Flute Carbide

Product Description

The ISCAR 3401282 is a single-end square end mill designed for precision milling operations in metalworking and machining applications. Manufactured from submicron solid carbide and coated with TiAlCN, this tool delivers extended tool life and heat resistance in demanding cutting environments. The 7/16 inch diameter cutting face, 1-1/2 inch length of cut, and 4-inch overall length make it well suited for slotting, peripheral milling, and finishing passes. A 38-degree helix angle and variable index geometry reduce chatter and improve surface finish. Centercutting capability allows direct plunge entry without a pre-drilled pilot hole.

This end mill is appropriate for use in vertical and horizontal machining centers, CNC mills, and manual knee mills where tight tolerances and surface quality are required. It is used primarily by machinists and tool-and-die professionals working with ferrous alloys, stainless steels, and high-temperature alloys where a TiAlCN coating provides thermal and oxidation resistance. The right-hand cutting and right-hand flute direction suit standard spindle configurations found in most production and job-shop environments.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance
• TiAlCN coating provides high-temperature oxidation resistance and extended cutting life
• 38-degree helix angle improves chip evacuation and reduces cutting forces
• Variable index flute spacing minimizes vibration and chatter during aggressive cuts
• Centercutting design allows direct plunge milling without pilot boring
• Right-hand cut and right-hand spiral compatible with standard CNC and manual mill setups

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 7/16 inch collet or end mill holders used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank in a properly sized collet or end mill holder to the full recommended grip length to prevent pullout under load. Verify runout with a dial indicator before beginning production cuts.
