Kyocera TLB04350 Milling Insert LOMU100408ER-GM PR1525

Product Description

The KYOCERA TLB04350 is a solid carbide milling insert carrying grade PR1525 with a MEGACOAT NANO PVD coating. Designated by ISO code LOMU100408ER-GM, it is a rectangular, right-hand, single-sided insert sized 10.90 mm in length, 6.60 mm wide, and 4.00 mm thick. The insert features four cutting edges with a honed edge style and a positive rake geometry. An ER-GM chip breaker controls chip flow during milling operations. Corner radius measures 0.80 mm (approximately 1/32 inch). This insert is installed by machinists and CNC tooling technicians performing milling operations on steel and stainless steel workpieces in production and job-shop environments.

This insert is engineered for milling applications on steel and stainless steel workpieces. It is compatible with the MEW and MEWH cutter series. The positive rake geometry and MEGACOAT NANO PVD coating are suited for demanding cutting conditions where edge wear resistance and surface finish quality are critical. Maximum depth of cut reaches 0.4291 inches, making it applicable to moderate-to-aggressive milling passes on ferrous materials in both light manufacturing and heavy production settings.

Key Features

• PR1525 grade with MEGACOAT NANO PVD coating for wear resistance on steel and stainless steel
• Four cutting edges per insert for extended tool life and lower per-edge cost
• ER-GM chip breaker geometry promotes controlled chip evacuation
• Positive rake design reduces cutting forces on workpiece material
• Honed cutting edge style for consistent edge integrity
• Screw-on insert holding method for secure, repeatable seating in compatible toolholders

Compatibility

Compatible with the MEW and MEWH cutter series. Fits toolholders designed for LOMU100408ER-GM insert geometry per ANSI and ISO standards.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before inserting or removing cutting inserts. Use the correct torx or hex key specified for the clamping screw of the toolholder to avoid stripping the screw seat. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
