Seco 02526639 Milling Insert SNHQ120516TR4-M07 F40M Carbide

Product Description

The SECO 02526639 is a solid carbide milling insert carrying the ANSI/ISO designation SNHQ120516TR4-M07 and manufactured to grade F40M with a fine-grain carbide substrate. It features a square shape with a 90-degree included angle, four usable cutting edges, and a right-hand orientation. The insert is PVD-coated with a TiAlN and TiN multilayer finish to extend tool life in demanding milling operations. Cutting edge style is T-Land with a negative rake angle of 20 degrees, providing edge strength when engaging hard and abrasive workpiece materials. The M07 chip breaker geometry supports a wide range of cutting conditions across steel, stainless steel, cast iron, superalloys, and titanium.

This insert is intended for use in milling applications on CNC machining centers and manual knee mills where square inserts in the SNHQ-12 series are required. Compatible cutter series is 335.19-12. Primary workpiece materials include steel, cast iron, superalloys, and titanium. Secondary workpiece materials include cast iron and non-ferrous metals. The insert is held in the cutter body by a screw-clamp method and is single-sided, meaning all four cutting edges are on one face. Typical users are machinists and tooling technicians in job shops, aerospace, and general manufacturing environments.

Key Features

• Four cutting edges per insert, right-hand orientation, single-sided
• T-Land cutting edge style with negative 20-degree rake for improved edge strength on hard materials
• M07 chip breaker geometry suited for steel, stainless steel, cast iron, superalloys, and titanium
• Meets ISO standards; compatible with cutter series 335.19-12 via screw-clamp holding method

Compatibility

Designed for use with cutter series 335.19-12. ANSI and ISO code SNHQ120516TR4-M07. Suitable for machining steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium workpiece materials.

Installation Notes

Installation is performed by machining technicians using the screw-clamp insert holding method specified for the 335.19-12 cutter body. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key for the insert screw as specified by the cutter body manufacturer. Inspect the insert pocket and seating surface for chips or damage before seating the new insert to ensure proper edge engagement and runout.
