Running this tool inside a cavity smaller than 40mm will cause the tool holder's heel or clamping screw area to rub against the internal wall of the component, resulting in friction heat and tool failure.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"beyond-faq-item\"\u003e\n\u003cdiv class=\"beyond-faq-q\"\u003eQ: Can I use TCMT 1604xx series inserts on this holder instead of TCMT 16T3xx?\u003c\/div\u003e\n\u003cdiv class=\"beyond-faq-a\"\u003eA: No, you must use the standard 16T3 dimensions (thickness 3.97mm). An ISO 1604xx insert is thicker (4.76mm), meaning it will sit too high in the pocket, altering the tool's true center-height alignment and destabilizing your cutting geometry.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"beyond-faq-item\"\u003e\n\u003cdiv class=\"beyond-faq-q\"\u003eQ: What is the maximum stable overhang limit for this 32mm steel boring bar?\u003c\/div\u003e\n\u003cdiv class=\"beyond-faq-a\"\u003eA: For standard steel-shank holders, the recommended maximum overhang ratio is up to 3x to 4x the shank diameter.
