3+1 and Axis Substitution will be your friend here. Take the two section in between the two bosses and xform unroll the shape and then can use what ever 3 Axis toolpath you would want in a 4 Axis output to rough and finish them in. They will not be normal to the walls they will be normal to the floor. Then you use a Stock model to see the left over stock and finish the vertical walls at A0 and A180. Using a 3/8 ball endmill will eliminate any transition between both areas and the rest is just rotated planes.

Sorry, I just reread it. I'll figure it out. Thanks though

Ok, now I get it, f or me, gauge length is from spindle to tool tip (as in image) that's why I was confused.

This. Drill to nearly break through, then spiral ramp with an 8mm cutter so you have plenty of tool movement through the cross hole to the solid, then continue drilling.

We use a ton of dampened holders here. Most are super long dampened bars from Sandvik. It's their silent tool line. In our case they accomplished what non dampened holders couldn't do.

This error message is directly related to the DLL file, when the VCRUNTIME140.DLL file is misplaced or deleted from the Windows system and you will face this error message. This error indicates a problem with the 2015 version of the Visual C++ Redistributable because there is a known conflict between the 2017 version and the 2015 version. Please follow these steps: Open Programs and Features form Control Panel Uninstall the 2017 version of the C++ Redistributalbe, if that is installed on your System. Then from the link below, download and install the 2015 version, then once that is installed, download and install the 2017 version. https://docs.microsoft.com/en-GB/cpp/windows/latest-supported-vc-redist?view=msvc-170 Please Note, regardless of whether your version of Windows 10 is 32bit or 64bit, you must download and install both the x86 and x64 versions, do not try to install the ARM64 version. DLL or Dynamic Link Libraries are external parts of applications and services that run on the Windows system. DLL files are the important part of any computer / laptop and we cannot imagine an operating system without DLL files. A single DLL file can be shared by more than one application and services. That is why, when a dll file gets corrupted / deleted / moved from the system, all linked applications start launching DLL errors. Sometimes, this error message also starts to appear after installing a Windows update or an incorrect installation of any program. This is for the reason that, in all the latest updates or patches released by Microsoft, there may be a missing system file or dll file.
