The aggressive milling grade
The MS3501 milling grade is engineered to dominate in ferritic and martensitic stainless steels, precipitation‑hardened steels, superalloys, high‑alloy steels and stainless steels.MS3501 is our latest milling grade engineered to dominate. Its micro‑alloyed, heat‑resistant carbide core and CVD coating deliver exceptional stability in materials with low thermal conductivity, superalloys, precipitation hardened steels, and high alloy steel and lets you push cutting speeds without fear of thermal breakdown.
At the same time, advanced pre‑ and post‑treatment processes shut down built‑up edge, chip‑welding, and chatter in materials with high adhesiveness. The result is a grade that runs cooler, cuts cleaner, and stays sharper across the most demanding combinations of heat, stickiness, and stress.
Your Challenge:
Heat‑resistant and adhesive materials overload inserts with extreme temperature, chip‑welding, and unstable cutting forces. This forces slower feeds, unpredictable tool life, and higher risk of scrap.
Our Solution:
The heat‑resistant substrate, robust CVD coating, and friction‑reducing surface treatments of the MS3501 work together to deliver stable, controlled cutting in both high‑heat and high‑adhesion applications. It unlocks higher speeds, longer tool life, and consistently clean results.
Built to withstand machine instabilities
Not every setup is perfect and MS3501 is designed for that reality. The coarse‑grained carbide substrate, strengthened binder phase, and tough Ti(C,N)–Al₂O₃ CVD coating combine to deliver exceptional resistance to chipping, thermal shock, and cracking. Whether you’re deep in a pocket, pushing through a long roughing pass, or dealing with a machine that’s seen better days, MS3501 stays intact and on track.
Your Challenge:
Unstable fixturing, older machines, or varying loads trigger fractures and inconsistent results with conventional grades.
Our Solution:
MS3501 absorbs impact and resists thermal cycling thanks to its engineered substrate and robust CVD coating. It keeps edges alive even when the environment isn’t ideal.
Zero waste means maximum value
Wasting insert edges is money lost – it’s as simple as that. MS3501 ends the guessing game with Used Edge Detection technology, giving operators instant clarity on remaining edges. No missed corners. No premature discard. Just full utilization, lower tooling costs, and a more sustainable process. It’s intelligent, intuitive, and built for shops where efficiency is expected.
Your Challenge:
Operators unintentionally scrap inserts with unused edges, driving up tooling cost per component and creating unnecessary waste.
Our Solution:
Used Edge Detection makes edge status unmistakable and ensures every edge is used to its full potential before the insert is replaced.
Versatility that simplifies your entire workflow
The wide application window of the MS3501 dramatically reduces grade changes and simplifies tool logistics. Whether you’re running mixed batches or switching materials shift‑to‑shift, MS3501 maintains the same aggressive performance profile. More uptime. Less complexity. Stronger output.
Your Challenge:
Switching materials often means switching grades resulting in interrupted production, increased inventory, and complicating planning.
Our Solution:
MS3501 delivers reliable performance across a wide spectrum of ISO P and ISO S materials, enabling you to run more jobs with fewer grades and more confidence.
Application area
MS3501, together with MP2051, represents the latest generation of grades built on our new micro‑alloyed, coarse‑grained cemented carbide platform. Engineered for medium to rough machining, these grades excel in ferritic and martensitic stainless steels, precipitation‑hardened steels, superalloys, high‑alloy steels and stainless steels.
MS3501 is the high‑productivity solution in this range. Its cemented carbide substrate is paired with a robust CVD coating, significantly enhancing heat resistance and enabling aggressive cutting parameters. Advanced pre‑ and post‑treatment processes further reinforce toughness and surface smoothness, delivering superior performance in applications involving adhesive materials.
