Seco 00041523 Turning Insert VNMP331-M1-36 Carbide

Product Description

The SECO 00041523 is a solid carbide, uncoated turning insert in the VNMP-M1 series, designed for precision metal cutting in demanding machining environments. It features a 35-degree diamond shape (V-style insert) with a negative rake geometry and a sharp cutting edge, making it well-suited for interrupted cuts and high-strength workpiece materials. The inscribed circle measures 3/8 inches (0.3750 inches), the corner radius is 1/64 inches (0.0157 inches), and the insert thickness is 3/16 inches (0.1874 inches). The M1 chip breaker geometry supports controlled chip formation across a range of cutting conditions. This insert is installed by CNC machinists and toolroom technicians working on lathe and turning center setups.

The 00041523 is engineered primarily for superalloys and titanium (ISO material code S), with secondary applicability to steel, cast iron, non-ferrous materials, and hardened materials (ISO codes M, K, N, H). Typical applications include back turning, facing, profiling, and general turning operations. The insert accommodates a maximum depth of cut of 0.6142 inches and is compatible with insert lengths in the range of 0.7000 to 10.0000 inches, providing flexibility across a variety of part geometries and toolholder configurations. Its neutral hand orientation suits standard right-hand and left-hand toolholder arrangements.

Key Features

• Solid carbide construction, uncoated (bright finish) — suited for superalloys and titanium where coating adhesion or heat generation is a concern
• 35-degree diamond insert shape with negative rake for edge strength and stability under load
• M1 chip breaker geometry for controlled chip evacuation during facing, profiling, and turning
• Sharp cutting edge style optimized for clean entry into difficult-to-machine materials
• Two cutting edges per insert; neutral hand for versatile toolholder compatibility
• Clamp, pin, and lever-lock holding methods supported
• Meets ANSI and ISO standards; ISO equivalent: VNMG160404-M1

Compatibility

Designed for use in VNMP-style toolholders that accept a 35-degree diamond insert with clamp, pin, or lever-lock holding. ISO equivalent designation is VNMG160404-M1. Compatible with toolholder systems specifying insert size code 331 and clearance code N. Suitable for material grades S10, S20, and S30.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before seating or replacing inserts. Ensure the insert pocket and seating surface are clean and free of debris before clamping to prevent rocking or improper seating. Verify the correct clamping method — clamp, pin, or lever lock — matches the toolholder design before applying holding force.
