Product Features

  • Four flutes produce a better finish than fewer flutes
  • Square nose end mills (also called square end) create sharp, unrounded cuts
  • Titanium aluminum nitride (TiAlN) coating lubricates the end mill for high-temperature stability and abrasion resistance at high cutting speeds, offering better heat resistance than TiN and TiCN coatings
  • Carbide can run at higher speeds than high-speed steel, resisting abrasion and high cutting temperatures
  • Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling

Product Description

The Niagara Cutter C430 TiAlN-coated carbide square nose end mill has four flutes and a 30-degree helix angle for general-purpose machining on a range of materials. The tool’s square end creates 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. Four flutes produce a better finish than fewer flutes. 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 TiAlN coating resists heat better than TiN and TiCN coatings, increasing tool life and performance. It also offers increased hardness for abrasion resistance and may reduce the need for lubricants based on the application. (TiAlN 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” to -0.002”. 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.

I use the 1/4 inch 4 flute bit for cutting gator board and ultra board on a cnc. Running 250 inches per minute+ with a perfect cut. More than twice as fast as the 2 flute bits we use.

This cutter chews through aluminium at 10k RPM and 0.1" DOC. Great finish and no immediate edge chipping. The cutting diameter is accurate

Very good product. This cutter is sharp. Seems to be durable but as always, this is solid carbide so do not let it chatter.

Not much to say about a drill bit other than it performs as required. It puts holes in stuff and everything.

I haven't tried it on any other substances, but if you need a 1/8" end mill, this one works perfectly!

This is for the (Niagara Cutter N55800 Carbide Square Nose End Mill, Inch, TiAlN Finish, Roughing and Finishing Cut, 30 Degree Helix, 4 Flutes, 4" Overall Length, 0.094" Cutting Diameter, 0.125" Shank Diameter). Huge length/diameter ratio makes this a little difficult to use without vibration but it's great for those hard to reach places!

SUPERLATIVE QUALITY!!! But (laugh at me):
SADLY (just testing the idea), this is NOT a drill bit, I.E., it doesn't have a conical POINT to hold it steady. It is meant for a MILL.
The idea of a precision carbide drill bit that could cut metal drew me to the flame with its allure.
It has 4 points around the tip to cut with.
So cool. So close. Sigh...

Worked well for a week, but broke as soon as I accidentally applied slight pressure at an angle. Not unexpected in a bit this tiny, but so far my set from Seaboltd is outlasting this one, and they're longer.
