1-1/4" Diam 4-Flute 30&deg MPN:66138-00-W

The 1 inch diameter 4-flute 30-degree end mill is an excellent choice for machinists who require precision cutting tools that can handle complex designs. Its unique helix angle allows for faster, smoother plunge cuts and better chip evacuation during rapid movement, making it ideal for applications requiring high feed rates without compromising precision. The flute design minimizes chipping and eliminates built-up edge formation on the cutting edge, resulting in longer tool life compared to traditional 90-degree end mills. Made from high-quality materials, this end mill offers increased durability and resilience while maintaining accuracy and providing superior surface finishes. Overall, its versatility and precision make it a must-have for any professional machinist's toolkit.
