Iscar 3104198 Indexable Face Mill 6.49in 45 Degree

Product Description

The ISCAR 3104198 is a 45-degree chamfer angle indexable face mill designed for precision face milling operations in metalworking and machining environments. Built in the 16Mill series, it features a 6.49-inch maximum cutting diameter, a 2-inch arbor hole, and accepts 10 ONH-compatible inserts secured by screw-type insert holding. With a maximum depth of cut of 0.217 inches and a right-hand cutting direction, this cutter is suited for high-feed roughing and finishing passes on ferrous and non-ferrous workpiece materials. It is installed by machining professionals in production and job-shop settings.

The 3104198 is used in horizontal and vertical milling machine setups where a large-diameter face mill is required for surfacing operations. The 45-degree lead angle reduces axial cutting forces and allows for lighter insert loads per pass, making it well suited for machining thin-walled parts or workpieces with limited fixturing rigidity. With 10 flutes and full ISO standards compliance, this cutter supports consistent, repeatable surface finishes in production volumes. It is a right-hand cut tool intended for arbor-mounted spindle configurations with a 2-inch bore.

Key Features

• 6.49-inch maximum cutting diameter with 6.0-inch minimum cutting diameter range
• 45-degree chamfer angle (F45NM cutter style) reduces radial and axial cutting forces
• Accepts 10 ONH-series inserts secured via screw-type clamping
• 10-flute configuration for high productivity and improved surface finish
• 2-inch arbor hole with 3.94-inch hub diameter for rigid arbor-mount setup
• Compliant with ISO standards; right-hand cut direction
• No coolant-through design; external coolant application applies

Compatibility

Compatible inserts include ONHQ-TN, ONHU 0806-N-PL, ONHU 0806AN-W, ONHU/ONMU 080608 AN-N-HP, ONHU/ONMU-08-TN-MM, and ONHU/ONMU-08-TN/HL. Maximum insert radius is 0.051 inches. This cutter is part of the ISCAR 16Mill series.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Before mounting or changing inserts, ensure the machine spindle is fully stopped, locked out, and the tool is secured in a suitable arbor fixture rated for the cutter diameter and weight. Use calibrated torque tools when seating insert screws to avoid over-torquing and insert damage. Follow the machine manufacturer and ISCAR tooling guidelines for maximum RPM and feed rate limits appropriate to this cutter diameter.
