Seco 02526685 Milling Insert SNHQ120404TL4-M07 F30M Carbide

Product Description

The SECO 02526685 is a solid carbide milling insert carrying the ANSI and ISO designation SNHQ120404TL4-M07. It features a square shape with four cutting edges, a left-hand insert orientation, and a negative rake geometry with a T-Land cutting edge style. The insert is coated with TiAlN and TiN via a PVD process, targeting wear resistance across a broad range of workpiece materials. At 0.1575 inches thick and 0.5000 inches inscribed circle diameter, it is sized to the SNHQ-12 series and fits the 335.19-12 cutter series. The micrograin carbide substrate supports the F30M manufacturer grade. This insert is installed by machinists and tooling technicians in milling operations on CNC and manual machining centers.

This insert is suited for universal material applications with primary compatibility across steel, stainless steel, cast iron, and hard materials, corresponding to ISO material codes H, K, M, N, and P. It is appropriate for both roughing and semi-finishing milling passes where a T-Land edge preparation and M07 chip breaker geometry are called for. The maximum depth of cut reaches 0.1437 inches, and the cutting edge effective length measures 0.1575 inches. Typical install scenarios include face milling and shoulder milling operations in job shop and production environments where consistent chip control across mixed workpiece materials is required.

Key Features

• Solid micrograin carbide substrate in manufacturer grade F30M for wear resistance in demanding cuts
• TiAlN and TiN PVD coating supports dry and semi-dry cutting across steel, stainless steel, cast iron, and hard materials
• Four cutting edges with left-hand orientation maximizes insert utilization per tool change
• Negative rake angle with T-Land cutting edge style provides edge strength on difficult materials
• M07 chip breaker geometry promotes reliable chip evacuation across universal material grades
• Screw-held mounting method with 90-degree included angle fits standard SNHQ-12 series pocket geometry

Compatibility

Designed for use in the SNHQ-12 series and confirmed compatible with the 335.19-12 cutter series. Insert style code is SNHQ120404TL4-M07 per both ANSI and ISO standards.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the spindle before seating or removing inserts. Use the correct torx or hex key torque driver specified by the cutter body manufacturer for the screw-held pocket — do not overtighten or use impact tools on insert screws. Inspect the pocket seat and clamp screw for damage before installing a new insert.
