Geometry Inserts Target Difficult-to-Machine Material Groups

Allied Machine and Engineering displays its newest addition to the T-A Pro high-penetration drilling system — the M geometry insert — at IMTS in booth #431436 in the West Hall. With the release of the ISO-material class M geometry, targeting stainless steel and high-temp super alloy (HRSA) materials, and proprietary margin design paired with the development of the new AM460 coating, Allied Machine says it is able to provide a tool that offers low cutting forces, excellent penetration rates and long tool life in challenging stainless high-temp super alloys. The new insert geometry produces ideal results with the newly designed T-A Pro holders, the company notes, but is also compatible with T-A holders.

When asked for the single most important feature of this technology for a mold builder, Allied Machine points to the insert’s geometry with proprietary margin reliefs, which is said to significantly reduce the amount of heat around the outside diameter of the cut. It also provides a simple drilling solution for an otherwise difficult-to-machine material group like stainless steel, which moldmakers often use for either corrosion resistance or for medical-grade use.

In addition, the T-A Pro M geometry’s design elements enable for larger diameters — 1" and above — to be used on smaller or under-powered machines where additional setups on other machine tools would be needed, or where parts would need to be contracted out. The ability to run high speeds and light feeds gives additional flexibility.
