This Link is for the 22° ID chamfer cutter only (buy Shoulder Referenced Trimmer separately)
 
This chamfer cutter is designed to cut a 22-degree chamfer on the inner diameter (ID) of the brass case mouth.
 
It has 6 blades with a minimum cutting diameter of 4.5mm( .17 ).
 
The shank is centerless ground to slide-fit the shank hole with approximately a 0.01mm gap, therefore, the trimmer won’t wobble when rotating due to the high levels of concentricity.
 
This cutter is made of M2AL-HSS, making it extraordinarily sharp and durable.
