Description of Niagara Cutter N88621 Finishing Diameter

4 Flute design for creating finer finishes and creating a higher metal removal rate. General purpose end mill for working on all types of materials. Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys. Titanium Carbonitride(TiCN) allows for optimal end mill and machine tool performance with it's ability to increase material removal rates 3 to 5 times that of uncoated tools. Center Cutting End Mills are designed with "End Teeth" making these ideal for applications such as profiling and slotting.

Not Long - End Mill

The first beginning cuts were good. Combustion did not last long even with constant use of cooling lubricant. Milled the shutter at 870 rpm.

Pros
  • Industry and Science
Cons
  • No Automatic

Not worth the money.

The worst end mill rattle I've ever seen. Suitable for roughing, but useless for finishing. I put in a .600 and hit a 2x3 pocket and it didn't break so that's good. But finishing the .005 around the 2500 inch circumference left a lot of vibration marks, which isn't great. I will not buy another end mill from this company.

Pros
  • Milling Machine Accessories
Cons
  • Disappear

I gotta remember you can't go wrong with Niagara Mills

. First a simple phone call to ask questions about each review to make sure they know what they are talking about before taking their opinion seriously. One person says that at the *FULL DIAMETER* depth of cut it will vibrate in the axial direction and 0.005 inch in the radial direction. Another states that it burned out when running a half-inch end mill against hardened steel (actually very hard) at 870 rpm. This is high-speed steel. Guys, no carbide. Personally, I don't take HSS above 300-400

Pros
  • End Mills
Cons
  • Not sure
