Holder includes our Power Coat nut that holds 75% tighter.<br />

NOTE: ER 11, 16 and 20 tool holders come with hex nut as standard.<br />

For slotted nuts simply add SLOTNUT to the end of the part number.<br />

For holders with coolant nut included add -C to the end of the part number.<br />

Properly torque down the nut for best tool life. See the Torque Chart on the back cover.
