The above toolholders have a 1.5º helix angle. For other helix angles, see page 122. Toolholders with prefix “N” cannot be used<br />
with an anvil. Holders with coolant channel available as standard. For ordering code, see page 95.<br />
The above toolholders are for RH inserts. For LH inserts, add LH to the toolholder’s ordering code.<br />
