VIERDWIN 3-Flute Carbide Roughing End Mill 2-Pack - 1/4 Shank For Aluminum & Alloys

About This Product

Alright CNC folks, listen up - these VIERDWIN roughing end mills are absolute workhorses for aluminum and soft alloys! The 3-flute design with that DLC (Diamond-Like Carbon) coating just tears through material while lasting way longer than standard bits. We're talking 1/4-inch shank that fits most CNC routers, with 1/2-inch cutting diameter and 3/4-inch cutting length - perfect for serious material removal without breaking a sweat. The DLC coating isn't just marketing fluff either - it genuinely reduces friction and prevents built-up edge that can ruin your finish. I've used these on everything from aluminum panels to copper parts and the finish comes out clean with minimal cleanup needed. The two-pack is smart because let's be real, having a backup when you're in the middle of a job is priceless. They handle high-speed machining like champs while maintaining stability that cheaper bits just can't match. Whether you're running production work or hobby projects, the cut quality is consistently impressive with less vibration than I expected from roughing end mills. The specs are solid too - 2.5-inch overall length gives you good clearance, and the carbide construction handles the heat without losing hardness. For the price, getting two professional-grade end mills that perform this well on aluminum, copper, magnesium, and composites is honestly a steal. They've become my go-to for initial roughing passes before finishing operations - reliable, predictable, and they just keep going through material after material.
