Product Feature

• Extended-reach neck style provides access to recessed areas of the workpiece
• Four flutes produce a better finish than fewer flutes
• Square nose end mills (also called square end) create sharp, unrounded cuts
• Aluminum titanium nitride (AlTiN) coating lubricates the end mill for high-temperature stability and abrasion resistance, offering better heat resistance than TiN, TiAlN, and TiCN coatings
• Carbide can run at higher speeds than high-speed steel, resisting abrasion and high cutting temperatures

Product Description

The Niagara Cutter CN430M metric AlTiN-coated carbide square nose end mill with extended-reach neck style has four flutes and a 30-degree helix angle for general-purpose machining on a range of materials. The extended-reach neck style provides greater access to recessed areas of the workpiece than tools with a standard neck style. Four flutes produce a better finish than fewer flutes. The tool’s square end has straight cutting edges that create sharp, unrounded cuts, and 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. 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.

The AlTiN coating resists heat better than TiN, TiAlN, and TiCN coatings, increasing tool life and performance. It also offers increased hardness compared to TiN and may reduce the need for lubricants based on the application. (AlTiN is suitable for a range of materials, but TiCN or uncoated end mills are recommended for machining aluminum.) The carbide substrate is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. Cutting diameter tolerance is +0.000 mm to -0.050 mm. The round shank accommodates a variety of holders.

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.

The best value for you money! Great cutting I am surprised how precise the cuts where and how easy it devoured my stainless steel. I am a hobbyist and have a rather low performance CNC mill but the Niagara cutters more than compensated for my lack of power. However the metric documentaion is somewhat lacking. The charts on cutting feeds and speeds are based on 6 -10-12 mm so if you have a 8mm end mill you will have to figure it out your self. Also documentation is lacking on the metric ones when it comes to different coatings.
