LNMU0303ZER-ML Milling Inserts

Taizhou OYT’s milling insert is as versatile as it is reliable—perfect for tackling everything from carbon and alloy steels to stainless varieties like 304 and 316, even cast iron. It holds up beautifully against tough materials and abrasive surfaces, meaning fewer tool changes, less downtime, and smoother productivity day in, day out.  

When you choose to purchase OYT Machining’s LNMU0303ZER-ML milling inserts, you’re investing in a tool designed to boost productivity and reduce costs. The reinforced rake face and optimized clearance angles lower cutting forces and manage heat more effectively, allowing for higher feed rates without compromising surface quality or precision. As a direct replacement for the 1135 series, this double-sided insert doubles tool life by offering two cutting edges, delivering excellent value and efficiency. Additionally, the built-in chip breaker ensures clean, easy chip evacuation, preventing jamming and recutting even in challenging materials. For manufacturers seeking a smarter, faster, and more cost-effective milling solution, OYT Machining’s LNMU0303ZER-ML is the clear choice.

LNMU0303ZER-ML Milling Inserts

So what’s behind LNMU0303ZER-ML Milling Insert’s strength? It all comes down to the high-grade carbide substrate, shaped by OYT’s own sintering process. By fusing ultra-fine particles under intense heat and pressure, they create a incredibly dense and uniform structure. That gives the insert serious resistance to wear, chipping, and thermal shock—even under high-speed or heavy-duty conditions. You end up with a tool that lasts longer and performs consistently, cut after cut.

Rated for materials up to HRC 45, The LNMU0303ZER-ML Milling Insert is built for the tough stuff. Its clever edge design—with a reinforced rake face and tuned clearance angles—lowers cutting forces and manages heat better. That lets you ramp up feed rates beyond what standard inserts can handle, so you remove more material faster without sacrificing surface quality or precision. Bottom line: you work smarter, finish faster, and save on cost per part.

As a direct replacement for the 1135 series, this double-sided insert gives you two edges instead of one—effectively doubling tool life and boosting value. Plus, the built-in chip breaker keeps things tidy by breaking chips into small, easy-to-clear pieces. No more jamming or recutting, even in stringy, chip-prone materials. Everything runs cleaner, longer, and with less hassle.
