Take metal cutting to the next level with the Lenox MetalMax 3 in. Diamond/Metal Metal Cut-Off Blade. Designed for die grinders, this blade blends industrial diamond action with metal-cutting precision to deliver fast, clean cuts on metal stock while standing up to repeated use in demanding shop environments.
Why this blade stands out
-
Diamond/Metal construction targets tough metal surfaces with exceptional wear resistance, helping the blade stay sharper longer and deliver consistent cuts through steel, stainless steel, and other hard alloys.
-
3 in. diameter with a 3/8 in. arbor provides compatibility with a wide range of standard die grinders, making it a versatile addition to your toolkit.
-
0.050 in. thickness strikes a balance between aggressive cutting and control, producing precise profiles with reduced burrs.
-
Maximum speed 20,300 rpm ensures the blade performs at high revs for quick cuts while maintaining durability under load.
-
Single blade in bulk packaging makes it ideal for workshop stocking and replacing worn blades without overpaying for packaging.
-
Brand and lineage—Lenox MetalMax blends trusted LENOX engineering with a specialized metal-cutting profile for professional results.
Ideal use cases
Perfect for fabrication shops, automotive work, and maintenance tasks where metal must be cut efficiently. Use it to trim brackets, channels, tubing, and other metal stock on a die grinder, where precise, fast cuts save time and reduce secondary finishing. Its diamond/metal formulation helps maintain edge integrity during repeated cuts, so you aren’t stuck swapping blades mid-project.
How to get the best results
- Operate your die grinder at or below the blade’s maximum speed of 20,300 rpm to preserve edge life and cut quality.
- Secure the workpiece and use steady, moderate feed pressure—let the blade do the work to minimize heat and edge glazing.
- Ensure the arbor size matches your tool (3/8 in. arbor) and use proper guards and PPE for metal-cutting applications.
- Inspect the blade for wear and replace when cutting performance declines to maintain clean, safe cuts.
