Niagara Cutter ST570 Cobalt Steel End Mill, General Purpose, Regular Length, TiCN Coated, 2 Flutes, Square End, 7/16" Cutting Length, 3/16" Cutting Diameter Reviews
Niagara Cutter ST570 Cobalt Steel End Mill, General Purpose, Regular Length, TiCN Coated, 2 Flutes, Square End, 7/16" Cutting Length, 3/16" Cutting Diameter Feature
- Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool's ability to remove material
- High-performance powdered-metal cobalt for toughness and resistance to heat and wear
- Titanium carbon nitride (TiCN) coating lubricates the end mill for high-temperature stability and offers better abrasion resistance than TiN coating
- Square nose end mills (also called square end) create sharp, unrounded cuts
- Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling
The Niagara Cutter ST570 TiCN-coated T15 cobalt square nose end mill has two flutes and a 30-degree helix for general-purpose milling applications in high-temperature alloys and a wide range of materials. The two flutes have better chip-carrying capacity than end mills with more flutes while offering additional support when the tool goes deep into the material in applications with a high depth of cut. The 30-degree helix angle supports general-purpose applications. It balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action.
High-performance powdered-metal cobalt (T15) is high-speed steel (HSS) alloyed with cobalt, tungsten, and vanadium, which provides better heat and wear resistance than high-speed steel, and increased toughness when compared to general-purpose cobalt. The TiCN coating lubricates the end mill for high-temperature stability, and offers increased hardness and greater abrasion resistance than uncoated or TiN-coated tools. The tool’s square end creates sharp, unrounded cuts. The center-cutting design has cutting teeth at the end of the tool, so it can be fed into the workpiece like a drill bit. Cutting diameter tolerance is +0.001" to -0.000". 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.
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.
