Performance Advantages of WNMG080404-PV/43 Inserts
High Wear Resistance
Manufactured from advanced carbide substrates with optimized grain size and cobalt content.
Special coatings (TiN, TiAlN, or PVD/CVD multilayers) extend tool life under high-speed and dry-cutting conditions.
Stable Cutting Action
Neutral 0° relief angle ensures edge robustness, making it ideal for continuous and interrupted cuts.
Strong 80° trigon design provides resistance against tool breakage.
Superior Chip Control
PV chipbreaker allows smooth chip flow, preventing entanglement and improving surface finish.
43 geometry supports consistent chip formation in medium and fine turning.
Versatile Machining Capability
Suitable for steel, stainless steel, cast iron, and high-temperature alloys.
Works in both roughing and finishing operations.
Cost-Effectiveness
Double-sided design offers six cutting edges, reducing tooling cost per part.
Applications of WNMG080404-PV/43 Inserts
These carbide turning inserts are widely used across industries that demand high productivity and reliability:
Automotive Industry – Machining of engine components, shafts, gears, and brake systems.

What types of end mills are there?
Materials can be processed according to different types of end mills, categorized by the types of milling tools, including flat end mills, ball end mills, radius end mills, chamfer end mills, and end mills with chip breakers.
2025-05-23
PCD milling cutter is a polycrystalline diamond (PCD) milling cutter, which has a wide range of applications in the field of machining.

End mill for machining aluminum materials
Many customers have told us that ordinary end mills frequently stick when machining aluminum, and the accumulation of chips affects the accuracy, so they always change the tools. LIZHOU editor suggests that coated end mills are not recommended for aluminum materials, because some coatings contain aluminum elements. Therefore, it is better to choose uncoated end mills when selecting end mills for machining aluminum materials.
