Every machining application is different. If this tool is close to what you need but not an exact fit, General Cutting Tools can help customize it for your specific job, machine, material, or production requirement.
We work with CNC shops, industrial manufacturers, tool rooms, and production facilities to provide tool modifications that help improve fit, function, performance, and efficiency. Whether you need a small adjustment or a more specialized cutting tool solution, our team can review your requirements and help determine the best way to modify the tool.
Custom tooling can help reduce setup time, improve accuracy, extend tool life, solve clearance issues, and support more consistent production results.
We can modify tool diameters to better match your application requirements, including cutting diameter changes, pilot diameter adjustments, step diameters, and shank diameter modifications.
Tools can be modified for specific reach, clearance, or setup needs. This may include overall length changes, flute length adjustments, reduced neck sections, extended reach designs, or shortened tools for improved rigidity.
Shank modifications can help ensure the tool fits properly in your holder, spindle, or machine setup. Common options include shank diameter changes, flats, weldon flats, reduced shanks, and custom holding requirements.
For applications that require multiple diameters or operations in a single tool, we can create or modify step tools to help reduce tool changes and improve production efficiency.
We can customize corner radius, chamfer angles, edge breaks, and other profile details to meet part print requirements or improve cutting performance.
Depending on the tool and application, flute length, cutting edge geometry, end cutting features, and relief angles may be modified to improve chip evacuation, cutting action, and tool performance.
Tool coatings can be selected or added to improve wear resistance, heat resistance, lubricity, and performance in specific materials such as steel, stainless steel, aluminum, cast iron, and high-temperature alloys.
Many cutting tools can be reground or resharpened to restore performance, extend usable tool life, and reduce replacement costs.
For unique part features, we can help provide special forms, custom profiles, custom radii, counterbores, countersinks, keyseat cutters, form tools, and other application-specific tooling solutions.
We can help modify or recommend tooling based on the material being machined, including aluminum, brass, bronze, plastics, stainless steel, hardened steel, cast iron, composites, and other industrial materials.
Send us your print, sketch, tool number, or application details. Our team can review your requirements and help determine whether this tool can be modified or if a custom tool would be a better solution.
