I recently bought a young reiner and I have continued using his previous bit, but need to buy my own for him. His bit at the moment has 7inch shanks and a port with a barrel.
I don't want a 'harsh' bit but I have no idea what to use or if I should get the same as what I use now (which works fine, but I don't know if it is a harsh type?).
I want to know what bits are softer or harsher
How do the different size shanks work? Shorter vs longer?
And the port, you can get them 'rectangle' with a barrel or you can get the curved etc... how do they work differently?
I will ask my trainer but won't see him for a few weeks so I wanted to get my research in
Thanks in advance!!
