The hammer is side airflow but airflow comes from the bottom, the path that the airflow goes makes the inserts to a new “logic”, not like the inner diameter of classic airflow pins, so here we will post our recommendation for different types of drags.
FOR DL – 2 short inserts for full airflow
– 1 short insert and 1 of the others
FOR RDL – 2 inserts with 2 holes
– 1 insert with 2 holes and 1 insert with one hole
FOR MTL- 2 inserts with 1 hole
– 1 insert with 2 holes and 1 insert without holes
– 1 insert with 1 hole and 1 insert without holes
TO CHANGE INSERTS
Inserts are made out of Peek, and they go by press fit, first times are hard to take out and to put in (also when are dry), but those MF are well made with quality material, so you can make pressure from the inside to outside to take them out without fear.
