Wrenches

Standard steel wrenches with moulded handgrip for ER and OZ slotted nuts.
In addition to the standard wrenches, torque wrenches are available for ER20, ER25, ER32 and ER40 nuts. These ensure the correct torque on the nut to maximise the clamping force on the cutter shank without overtightening, which can damage the collet. Each wrench has two settings: one for smaller cutter shanks up to 5-6mm and the other for cutter shanks over this size.
