Iscar 3105094 Square-shoulder Face Mill 2.5in Helitang

Product Description

The ISCAR 3105094 is an indexable square-shoulder face mill designed for precision milling operations in metalworking environments. Built in the Helitang series, this cutter holds 12 inserts and operates at a 0/90 degree lead angle, delivering clean, square shoulders in a single pass. It accepts T490 LN 1306 insert style inserts secured by clamp and screw, and features through-coolant capability to manage heat and chip evacuation during high-demand cuts. With a maximum cutting diameter of 2.5 inches and a maximum depth of cut of 1.41 inches, it suits medium-duty face milling on machining centers and mill-turn platforms. Licensed machinists and CNC operators are the primary users.

This face mill is suited for use on vertical and horizontal machining centers where square-shoulder profiling and face milling are required. The 4-flute configuration and Helitang geometry support consistent chip flow and reduced vibration across a range of ferrous and non-ferrous workpiece materials. The through-coolant feature makes it practical for deep shoulder cuts where flood coolant cannot reach the cutting zone effectively. It conforms to ISO standards, making it compatible with ISO-compliant tooling setups common in production machine shops.

Key Features

• 12-insert capacity at 0/90 degree lead angle for true square-shoulder milling
• Through-coolant support for effective heat management and chip removal in deep cuts
• Accepts T490 LN 1306, T490 LNAR 1306, and T490 LNMT/LNHT 1306 insert styles
• Clamp and screw insert holding for secure, repeatable insert positioning
• 4-flute Helitang series design for reduced cutting forces and smooth surface finish
• ISO-standard construction for broad toolholder compatibility

Compatibility

Compatible insert styles include T490 LNAR 1306 and T490 LNMT/LNHT 1306. Manufacturer catalog reference number is T490 SM-D2.5-14-4-1.0-13. This mill is designed for use with a 1 inch arbor hole and conforms to ISO tooling standards.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and machine power is locked out before mounting or removing the cutter. Verify insert seating and torque all clamping screws to the tool manufacturer specification using the appropriate Torx or hex key before running the cutter. Confirm coolant line connection and flow rate before initiating through-coolant operation.
