Stellram will showcase its latest cutting tools for aerospace applications, including its RSM programme for difficult-to-machine materials, at the Farnborough International Air Show.

The RSM solid-carbide end-mill tool offers a variable cutting geometry that is designed to overcome problems such as vibration and material tarnishing that are usually associated with machining titanium components.

Made from a hard-wearing, aerospace-approved micrograin carbide, it has a sharply honed cutting edge with positive primary and radial clearance angles for achieving stress-free penetration and chip evacuation.

The RSM tool features a reduced shank for greater flexibility in reach and work-holding lengths, making it suited for the profiling of walls, pockets and surfaces in 2D and 3D.

Stellram will also display a selection of programmes designed for fast metal-removal rates, including the 5230VS chevron milling cutter – a roughing tool for profiling and slotting applications – and the 7792VX high-feed milling cutter for use on high-temperature alloys and stainless steels.

ATI Stellram develops and produces high-performance cutting tools for difficult-to-machine materials used in a wide variety of industries including aerospace, power generation, medical, oil and gas production as well as automotive.


Its extensive product range comprises inserts and toolholders suitable for applications in drilling, grooving, milling, threading and turning.In addition ATI Stellram develops new grades and specialist combinations of substrates and coatings. Renowned for solving hard machining challenges, ATI Stellram has also established a reputation for developing innovative solutions designed to deliver better productivity, lower costs and higher quality, especially for the new generation of materials like nickel-, cobalt- and titanium-based alloys. ATI Stellram is a business unit of ATI Engineered Products and part of the ATI Aerospace team, a group of global businesses that produce a wide range of specialty metals and cutting tool solutions.


It has manufacturing facilities in the UK, Switzerland and the United States, and 9 sales offices around the world. ATI Stellram’s tooling engineers and metallurgists work closely with other specialists within the group to develop smarter solutions for difficult-to-machine materials.


This seamless technology transfer between the ATI companies provides an extensive knowledge base, not only of specialty metals, but also cutting tool performance.
