Seco 00030452 Ball Nose Milling Insert F25M Tialn

Product Description

The SECO 00030452 is a solid carbide ball nose milling insert designed for use in indexable end mills and milling cutters requiring precision profile cutting. Manufactured to the 218.20-125ER-M07 ANSI and ISO standard, this right-hand insert features a TiAlN and TiN PVD coating applied over a medium grain solid carbide substrate in manufacturer grade F25M. With a corner radius of 0.4921 inches, a thickness of 0.1988 inches, and an inscribed circle diameter of 0.4228 inches, it is built for consistent performance across a wide range of metalworking applications. It is held in place by a screw-type insert holding method.

This insert is suited for milling operations on steel, stainless steel, and cast iron in both general-purpose and demanding production environments. The M07 chip breaker geometry and positive rake angle support efficient chip evacuation and reduced cutting forces. It is compatible with the R218.20-25 and R218.20-01.00 cutter series. The insert accommodates a maximum depth of cut of 0.8660 inches and delivers two cutting edges per insert, making it a practical choice for CNC machining centers running medium-grain carbide tooling setups.

Key Features

• Ball nose insert shape for accurate profile and contour milling
• TiAlN and TiN PVD coating for wear resistance across universal workpiece materials
• F25M grade solid carbide with medium grain substrate for toughness and edge retention
• M07 chip breaker geometry supports positive rake cutting on steel and cast iron
• Two cutting edges per insert in a single-sided configuration
• Screw-type insert holding for secure, repeatable seating in compatible cutter bodies

Compatibility

Compatible with the R218.20-25 and R218.20-01.00 cutter series. ANSI and ISO code 218.20-125ER-M07. Suitable for use on steel, stainless steel, and cast iron workpiece materials per the manufacturer primary and secondary material designations H, P, M, and K.

Installation Notes

This insert is installed and replaced by a machinist or CNC tooling technician. Power down and de-energize the machine tool completely before changing inserts. Use the appropriate torx or hex key to seat the clamping screw to the cutter body manufacturer specification. Inspect the insert pocket and seating surface for debris or damage before installing a new insert to ensure proper seating and runout control.
