Porting bits

[mad_mat222]

Can anyone recommend carbide burrs etc for porting in particular certain Drexel bits. They have are big range. The cheap Chinese stuff is garbage unless someone wants to make a recommendations. Would like to see a list eg
-194
-125
-9904
etc
I do use some larger 1/4 shank carbide burrs but you can’t really go wrong with those if buying name brand and a shape you like. Thses mini burrs seem to dull really quickly.

Cheap Chinese ones off amazon work great. Been through several sets over the last few years.

The 1/8” shank drum sanding bits smooth out the carbide roughness.

I used the the China ones and had good luck, I’ve noticed I have to go slow or I destroy them. Then I use a split mandrel with 60grit to 1000 grit to smooth my exhaust ports
