Kyocera TLB09310 Milling Insert WNMU080608EN-GM PR1525

Product Description

The KYOCERA TLB09310 is a solid carbide trigon milling insert carrying grade PR1525 with MEGACOAT NANO PVD coating. It belongs to the MFWN series and is designed for face and shoulder milling operations where consistent edge life and surface finish on steel workpieces are required. The insert features an 80-degree included angle, six cutting edges on a double-sided body, and a honed cutting edge style. A negative rake geometry and EN-GM chip breaker work together to control chip flow and reduce built-up edge during interrupted or continuous cuts. Screw clamping secures the insert in compatible MFWN-series toolholders.

This insert is rated for primary use on steel (ISO P materials) and secondary use on stainless steel (ISO M materials), making it a practical choice for general machining shops, aerospace component work, and production turning cells that handle both material groups. The double-sided configuration delivers six usable cutting edges per insert, reducing per-edge tooling cost in high-volume milling programs. Neutral hand orientation allows use in standard right-hand and left-hand cutter bodies without stocking separate insert hands.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or indexing inserts. Secure the insert using the designated clamping screw; use the correct torx or hex key specified for the toolholder — do not overtighten. Inspect the insert pocket for chips or damage before seating a fresh edge to ensure proper seating and runout.
