## Description

The Niagara Cutter RFM440 uncoated (bright) cobalt steel rougher-finisher end mill has a non-center-cutting design and removes material in less time than conventional end mills while producing a finer finish than fine- or coarse-pitch roughers. The number of flutes varies by diameter to optimize the feed and cut rate. The cobalt steel substrate can be run at faster speeds and stays sharp longer than high-speed steel tools, while offering resistance to heat and abrasion. With no coating or surface treatment, this uncoated tool can be used on a broad range of materials.   Truncated rougher-finisher end mills are special-purpose tools whose chip-breaking cutting edges create small chips for heavy cuts and remove more material in less time than conventional end mills. They produce a finer finish than fine- or coarse-pitch roughers, reducing the need for a second finishing cut in some applications. The 30-degree helix angle balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. The tool’s square end creates sharp, unrounded cuts and has a corner chamfer on the cutting edges to provide more strength than standard square end tools in applications where cutting forces are high. The non-center-cutting design is for applications such as peripheral milling and finishing. Cutting diameter tolerance is +0.001” to -0.000". The end mill 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.   Niagara Cutter has been designing and manufacturing precision cutting tools since 1954. Specializing in end mills, cutting mills, and saws, the company is based in New York and manufactures its tools at facilities in Pennsylvania and Massachusetts. This allows the company control over production, from substrate to coating, which is essential for customers in a variety of industries, especially aerospace and automotive.

## Features

- Truncated rougher-finisher removes material in less time than conventional end mills while producing a finer finish than fine- or coarse-pitch roughers
- 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
- Uncoated (bright) tools have no additional surface treatment or coating for use on a broad range of materials
- Square nose end mills (also called square end) create sharp, unrounded cuts
