Engine mount bearing outer rings are typically made from Inconel 718 which is very tough and wear cutter teeth comparatively quickly. Unasis has developed an innovative design to specifically target this issue. Unasis Inconel Bearing Cutting Tools are coated with a specialist PVD material which is harder than Carbide. The novel teeth design targets tough materials and drastically improves performance.


Originally designed to support the Leap 1-B Engine Mount program, this tool style has since been retrofit to support CFM56-5B, CFM56-7B, V2500, CF6-80 along with many other popular engines.



Tools In Stock

Access to hundreds of tools from stock for the entire bearing swaging, cutting and testing process. Lead time may be extended for coating and sharpening process for upgraded tools.

Specialist Tool Coating and Performance

Only commercially available bearing cutting tool upgraded for us with Inconel 718 and other specialist high temperature steels. Specialist material and titanium coating specifically designed to perform better with exotic steel bearings. Proven to stay sharper for longer than the standard cutting tools.

Sprung Loaded Cutter Head

For portable options there is a sprung loaded cutter head which controls process to reduce wear on teeth. This eliminates the operator error with overloading the cutter teeth which could provide damage. This spring is stronger than normal to cut through tough materials.

Product Details

These specialist bearing cutter tools are available in both drill press and portable styles. The portable design also incorporates a stronger spring to provide optimum consistent force on the cutter teeth. This spring eliminates the operator’s determination of this force thus making the cuts repeatable over all operations.


These upgraded bearing cutting tools are not only for specialist bearings and can be used for the full range of bearing configurations. Your specialist Inconel bearing cutting tool will stay sharper for longer when used on standard MS or BACB bearings.


Just like our other cutters, this tool used to cut either the v-groove of a bearing, retention sleeve or v-groove of a housing. The process cuts a relief on the lip so it is able to be pressed out without damaging the housing. The design is carefully engineered with the outside diameter of the teeth smaller than the housing bore so it is impossible to cut the housing in operation. Please review our detailed instruction manual and instructional video for both training and process control for customer audit purposes noting these are for standard tools.
