Sandvik Coromant 7101033 Milling Insert N331.1A Grade 1130

Product Description

The SANDVIK COROMANT 7101033 is a solid carbide milling insert carrying the ANSI and ISO designation N331.1A-08 45 08H-WL1130. It belongs to the N331.1A series and is designed for shoulder and face milling operations across a broad range of workpiece materials. The insert features a rectangular shape with a 90-degree included angle, four cutting edges, and a positive rake geometry that reduces cutting forces. The AlTiCrN coating is applied via PVD process, providing thermal resistance and wear protection during demanding cuts. Thickness measures 4.45 mm (0.1752 inches) and width measures 9.5 mm (0.3740 inches). The WL chip breaker geometry supports stable chip control in general and finishing milling applications.

This insert is suited for milling steel, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials, covering material grades P30, M15, and N15. Typical applications include shoulder milling, slot milling, and ramping operations on machining centers and CNC mills in both production shop and job-shop environments. The neutral hand orientation allows use in standard toolholder setups without left- or right-hand restrictions. The WL chip breaker is optimized for light to medium depths of cut, making this insert a practical choice for finishing and semi-finishing passes on a variety of part geometries.

Key Features

• Solid carbide substrate with AlTiCrN PVD coating for extended tool life in abrasive and high-temperature cuts
• Four cutting edges per insert maximizes usage before replacement
• Positive rake geometry reduces cutting forces and heat generation at the edge
• WL chip breaker supports controlled chip evacuation in light to medium milling passes
• Corner radius of 1/32 inch (0.0315 inches) reduces edge chipping and improves surface finish
• Neutral hand designation allows fitment in standard right- and left-hand toolholders
• Screw-clamp holding method provides secure, repeatable insert indexing

Compatibility

Compatible with the SANDVIK COROMANT L331.52C cutter series. The insert uses screw-type holding and is sized to the 084508 insert size code per ANSI and ISO standards.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key for the clamping screw as specified by the toolholder manufacturer, and inspect the insert seat and screw threads for debris or damage before seating a new insert. Do not exceed the maximum depth of cut of 0.3031 inches to avoid insert overload or premature failure.
