The mistake made, is to cut the exhaust seat at 30 degrees, instead of degrees. Because, reducing the contact point, will burn out the valve. Also, keep in mind that tool holders, do wear out. Consequently, allowing the cutter to tip, during operation. The runout requirement is generally, between .001″ and .002″.

CVD is often used to apply TiCN and Al2O3 coatings on tools. Coatings applied with a PVD process may be extremely thin (only to 5 microns thick), but leave a sharper cutting edge best suited for slower cutting speeds. PVD coatings are often used on solid carbide tools as well as positive rake inserts. PVD coatings also work well on inserts ...

The top cut on the seat (usually 30 degrees), establishes the outer edge of the seat and helps turn flow into the combustion chamber. A 60 degree bottom cut sets the width of the 45°seat. The 45° exhaust seat is deliberately kept inboard of the outer edge of the valve otherwise hot exhaust gas will eventually erode the edge of the valve.

The exhaust is also harder to cut on the clones if I am not changing the exhaust seat. With the mill and the 3 angle cutter it takes a lot of time getting the pilot in alignment with the spindle driver for the cutter. One that is done the seat comes out perfect, I still do lap with 800 grit to see where the seat is.

A simple hand tool that uses the valve guide to center the cutting tool is a terrible idea. You will never get the seat face concentric with the guide bore. Most likely you will do more harm than good. The end result of using such tooling will be poorly formed seats, out of round seating faces, and none concentric to guides.
