Seco 74016055 Milling Insert 335.19-1205T-MD09 T25M Carbide

Product Description

The SECO 74016055 is a solid carbide milling insert carrying ANSI and ISO designation 335.19-1205T-MD09, designed for use in SECO 335.19-12 series milling cutters. The insert features a square shape with a 90-degree included angle, a negative rake angle of 15 degrees, and a T-Land cutting edge style with MD09 chip breaker geometry. The T25M grade CVD-applied TiCN coating provides wear resistance suited for machining steel, stainless steel, superalloys, and titanium. With four usable cutting edges on a single-sided insert, it delivers extended service life per unit. A screw-holding method secures the insert in the cutter body. This insert is installed by machinists and tooling technicians in CNC milling operations.

This insert is intended for medium-grain solid carbide milling applications across a range of ferrous and high-temperature alloy workpiece materials. Typical applications include face milling, shoulder milling, and general-purpose milling of steel, stainless steel, superalloys, and titanium in both production and job-shop environments. The MD09 chip breaker geometry is suited for moderate cutting conditions on these material groups. The insert fits SECO 335.19-12 series cutter bodies and is positioned as a standard indexable insert for medium-duty milling operations.

Key Features

• Solid carbide medium-grain substrate with CVD-applied TiCN coating for wear resistance in steel and high-temp alloys
• Square insert shape with 90-degree included angle and neutral hand orientation
• Four cutting edges per insert for extended tooling economy
• MD09 chip breaker geometry optimized for steel, stainless steel, superalloys, and titanium
• Negative rake angle of 15 degrees with T-Land cutting edge style for edge strength
• Screw-held mounting for positive insert location in compatible cutter bodies

Compatibility

Designed for use with SECO 335.19-12 series milling cutter bodies. ANSI and ISO code 335.19-1205T-MD09 identifies the insert geometry and size for cross-reference with compatible tooling systems. Verify cutter pocket geometry and insert seat dimensions before installation.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key specified by the cutter body manufacturer to seat the clamping screw to the correct engagement without over-torquing. Inspect the insert pocket seat for chips or debris before seating the new insert to ensure proper contact and runout.
