End Mill Geometry Enables Doubled Feed Rates

Niagara Cutter, a subsidiary of Seco Tools, recently launched its Stabilizer 2.0 next-generation family of end mills. The cutters in this series incorporate continuous, variable, asymmetrical geometries and provide smooth and chatter-free performance that can enable doubled feed rates compared with previous models, the company says. Because they handle twice the chip load, the new versions are said to substantially shorten part machining cycle times and further boost productivity.

The family includes the ST430.2 series designed for steels, alloy steels and cast iron as well as the ST440.2 HT series for ISO-M and ISO-S materials such as stainless steel, titanium and high-temp alloys. In addition to the performance boost provided by the new geometry, an advanced AlTiN coating offers resistance to heat and abrasion to optimize tool life.

The end mills come in diameters ranging from 0.125" to 1.0" and 3 to 25 mm, with square corner and corner radii ranging from 0.010" to 0.120", depending on series and diameter. Lengths are available in 1×D, 2×D and 3×D. Tools come with cylindrical shanks or, for diameters exceeding 0.375", with Weldon flats.

As with all Niagara solid end mills, Seco offers its Modification Program for quick turnarounds on modifications of the new tool. 


  • Inserts For Difficult Materials

    Economic efficiency is an important consideration when choosing tools for challenging metals.

  • Threading On A Lathe

    The right choices in tooling and technique can optimize the thread turning process.

  • Taking The Fear Out Of Hard Turning

    To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
