Description

The SECO 00094730 is a solid carbide milling insert carrying the ANSI and ISO designation OFER070405TN-M16, manufactured in grade F40M with a fine-grain carbide substrate. The insert features a PVD-applied dual coating of TiAlN and TiN for extended tool life in demanding milling operations. Octagon in shape with a neutral rake angle and T-Land cutting edge style, it delivers 8 usable cutting edges per insert. The wedge-clamp holding method provides secure seating in compatible cutter bodies. The corner radius is 0.0197 inches, and the maximum depth of cut reaches 0.2795 inches, making it well suited for moderate-to-aggressive face and shoulder milling passes.

This insert is designed for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium alloys. It is sized to fit the SECO R220.43-07 cutter series and any holder conforming to the OFER-07 series interface. Typical applications include face milling, shoulder milling, and high-feed profiling on machining centers and mill-turn platforms in job shop and production environments. The M16 chip breaker geometry is optimized for medium cutting conditions across the listed workpiece materials.

Key Features

Octagon insert shape with 8 cutting edges maximizes cost-per-edge efficiency
PVD dual coating (TiAlN and TiN) provides heat and wear resistance for steel and superalloy milling
Fine-grain F40M carbide grade balances toughness and hardness for interrupted and continuous cuts
T-Land cutting edge style improves edge strength and reduces chipping on hard or abrasive materials
Neutral rake and neutral insert hand allow use in a wide range of cutter orientations
Compatible with SECO R220.43-07 cutter series via wedge-clamp holding method

Compatibility

Designed for use with the SECO R220.43-07 cutter series. Conforms to OFER-07 series geometry per ISO standards with ANSI and ISO code OFER070405TN-M16.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the cutter body is de-energized and the spindle is fully stopped before seating or removing inserts. Use the correct wedge-clamp torque tool as specified by the cutter body manufacturer do not overtighten or substitute fasteners. Inspect the insert pocket and wedge for chips or debris before seating a new insert to ensure proper clamping force and runout.
