Lower your costs and improve your productivity with Seco Tool's newly expanded Niagara Cutter™ family of multipurpose 5-flute solid end mills.

Big tooling inventories cost you big money, and having to always use multiple end mills increases part costs and reduces your overall productivity.

Eliminate these problems with Seco Tools newly expanded Niagara Cutter™ ST540 family of easy-to-apply, multi-purpose 5-flute solid end mills.

The new end mills are part of Seco Tools Niagara Cutter™ Stabilizer™ product family, and their signature variable geometries bridge the gap between the Stabilizer™ 2.0 product family of Seco Tools and the S638, S738, S938 Multi-Flute product family.

The ST540 product family will help extend tool life and provide unsurpassed stability in a wide range of applications from slot milling to advanced roughing, side mill finishing and everything in between.

More on Milling

With more powerful milling tools available today than ever before, the big question facing machinists is how best to combine them to increase productivity, reduce cycle times, and improve tool life and surface finish.

There’s more to choosing the best end mill than its price tag and availability.

Climb milling is the most common method of milling a part whether it's the surface or periphery of a part. Climb milling as the name would indicate attempts to pull itself through the cut.
