• UPC   816550028445
• Complete Package: This all-inclusive kit features 5 pieces, each with a 1/4 inch shank size. It provides a range of cutting lengths from 12.7 - 25.4 mm (12.7/12.7/25.4/25.4/25.4), ensuring it meets your diverse requirements. Distinct Down Cut Design: This design pushes the material downward during the cutting process, providing a cleaner edge and leaving a finely finished top surface on the workpiece. It’s particularly effective when working with thinner materials that are better suited to being pushed into the machine bed, as opposed to being lifted by an up-cut spiral. Long-lasting Durability: The end mills in our set are coated with a nano blue coating. This coating is a thin layer that enhances the hardness of the end mills, making them more resistant to wear and tear. This means they can withstand extended use without losing their cutting edge, ensuring you get a consistent performance throughout their lifespan. The nano blue coating also provides heat resistance, which is crucial when milling at high speeds or working with hard materials. Superior Craftsmanship: Using 90 percent tungsten and 10 percent cobalt, we have re-proportioned the material for aluminum usage. Unlike other flute styles with a typical hardness (HRA) around 45-50, our end mills boast an impressive HRA of 91.5, providing cleaner cuts and allowing for deeper plunges Wide range of applications: The ultra-hardness of our cutter heads makes them highly effective when working with aluminium. They're also perfect for tasks such as pocketing, lettering, working with thin workpieces, vacuum clamping and more. Plus, the down-cut design is perfect for a smooth, professional finish on the top of your workpiece in the final pass.
