Drillco 1 4FL Single End End Mill 1 Shank (51A164F)
Drillco 51A164F 1" 4-Flute Single End End Mill with 1" Shank is engineered for precision machining, durability, and superior surface finishes. Unlike 2-flute end mills, the 4-flute design ensures that at least one—often two—cutting edges are engaged at any given time, resulting in smoother cutting action, reduced chatter, and improved dimensional accuracy. This makes it ideal for slotting, profiling, and finishing applications where a fine surface finish is required. Built with high-speed steel (HSS) construction, this end mill offers excellent wear resistance and long tool life, even in demanding milling operations. The single-end design allows for efficient cutting while maintaining rigidity and stability in use.
