- Roughing end mills have chip-breaking cutting edges that remove material in less time than conventional end mills
- Coarse-pitch tooth design and tool geometry are suitable for high-production metal removal on cutting- steel grades and many nonferrous materials
- Long-length end mills have longer cutting edges than standard- and medium-length end mills for increased cutting length
- Number of flutes varies by diameter for optimum feed and cut rate
- Cobalt steel resists abrasion and high cutting temperatures, and has higher feed rates than high-speed steel
Description
The YG-1 E2172 uncoated cobalt steel long-length roughing square nose end mill has a coarse pitch, multiple flutes, a non-center-cutting design, and a 30-degree helix for high-production peripheral metal removal on cutting-steel grades and many nonferrous materials. The end mill has chip-breaking cutting edges that create small chips for heavy cuts and remove material in less time than conventional end mills, with minimal vibration (chatter). It produces a rough finish that can be smoothed by a second finishing cut. Long-length end mills have longer cutting edges than standard- and medium-length end mills for increased cutting length. The number of flutes varies by diameter to optimize the feed and cut rate. The tool�s square end creates sharp, unrounded cuts. The non-center-cutting design is for peripheral milling and allows the tool end to be resharpened. The 30-degree helix angle supports general-purpose roughing applications. It balances lower angles� strong cutting edge for difficult-to-machine materials with higher angles� increased cutting action. Cobalt steel can be run at faster speeds and stays sharp longer than high-speed steel tools, while offering resistance to heat and abrasion. This tool has no coating or surface treatment. Cutting diameter tolerance is + 0.0030 to - 0.0000" for up to 1" cutting diameter and + 0.0060 to - 0.0000" for over 1" cutting diameter. The tool has a Weldon shank. End mills are designed to remove material and create multi-dimensional shapes and profiles. They have cutting edges along the outside diameter and flutes that remove chips from the cutting area and allow cooling fluids to enter. If heat is not reduced effectively, the tool�s cutting edges will dull and additional material buildup can occur. The number of flutes can range from two to eight. Two-flute designs offer the most efficient chip removal, but more flutes provide a smoother finish. The shank is the end of the tool held in place by a tool holder or machine. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. Non-center-cutting end mills are for applications such as peripheral milling and finishing, but cannot make plunge cuts. YG-1 manufactures drills, taps, end mills, and rotary tooling. The company, founded in 1981, is headquartered in South Korea and has a U.S. office in Vernon Hills, IL.
