Iscar 3181022 Square-shoulder Face Mill 1.5in 6 Insert

Product Description

The ISCAR 3181022 is an indexable square-shoulder face mill designed for precision milling operations requiring a true 90-degree shoulder. Built to Helitang series standards, this cutter accepts six T490 LN 1306 style inserts and delivers a maximum cutting diameter of 1.5 inches with a maximum depth of cut of 1.43 inches. The 0/90 lead angle geometry supports clean, square-wall milling passes. Through-coolant capability keeps cutting temperatures in check during sustained metal removal. Licensed machinists and CNC programmers typically spec this tool for face milling and shoulder milling applications on machining centers where insert changeability and repeatability are priorities.

This face mill is suited for use on vertical and horizontal machining centers in job shop and production environments. The 0.75-inch arbor hole diameter fits standard arbor mounting configurations common to light-to-mid-range spindles. With a hub diameter of 1.4 inches and an overall height of 2.44 inches, the body fits compact tooling setups. The Helitang series designation indicates helical cutting geometry, which distributes cutting forces progressively and reduces chatter on interrupted cuts or harder workpiece materials.

Key Features

• 1.5-inch maximum cutting diameter with 0/90 lead angle for true square-shoulder milling
• Accepts 6 inserts in T490 LN 1306 style, including T490 LNAR 1306 and T490 LNMT/LNHT 1306 variants
• Maximum depth of cut: 1.43 inches
• Through-coolant ports for active chip and heat management
• Insert holding via clamp and screw for secure, repeatable seating
• ISO-standard tooling geometry; Helitang series helical flute design reduces cutting forces

Compatibility

Compatible inserts include T490 LNAR 1306 and T490 LNMT/LNHT 1306. Cutter style designation is T490 SM-13. Designed as an OEM-style fit for machining center arbors with a 0.75-inch arbor hole diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle and machine are powered down and the tool changer is in a safe state before mounting or removing the cutter body. Verify arbor fit and torque the retention hardware according to the machine tool manufacturer specifications before running. Confirm through-coolant lines are connected and unobstructed before initiating a cutting cycle.
